Info on python SDK variable definition
by Gianluca Cecchi 27 Feb '20

27 Feb '20

Hello, suppose in a .py using sdk I have my_var1 = 'prefix' then in the workflow I get at runtime another my_var2 that for example has the attribute my_var2.name that equals "suffix" Then I want to define a new variable my_var3 with value "prefix_suffix", where the string "suffix" is known only at runtime, how can I get it? my_var3 = ??? Can I use something similar to what I do when using the print function? print ("My storage domain is %s..." % sd.name) ? Thanks, Gianluca

oVirt Python SDK and monitor export as OVA task
by Gianluca Cecchi 27 Feb '20

27 Feb '20

Hello, sometimes I have environments (typically with Oracle RDBMS on virtual machines) where there is one boot disk and one (often big, such as 500Gb or more) data disk. The data disk has already its application backup (typically RMAN) and I want to complement it with a backup of only the boot disk of the operating system and VM configuration. I'm almost done completing a script using oVirt Python SDK and sharing for comments. I could be wrong, but I didn't find any ansible module to do this with Ansible playbooks: I can only save all the VM, that in my case wouldn't be necessary and instead time and storage wasting. The basic steps are: - make a snapshot of the target vm, composed only by the boot disk - clone the snapshot - export the clone as OVA - delete clone - delete snapshot There are some things to discuss about, probably when I will share the overall job (such as the name to give to the boot disk, if not using the bootable flag, the way to import the OVA in case of actual need, where you will have to comment out some fs entries related to missing disks, ecc.). The only thing missing is how to monitor the export to ova task that, as with Ansible, it completes almost immediately, while the export is actually altready running. I need to monitor it, so only at its real end I can run the last 2 steps of the above list of tasks. Can you give me any hint? Not found very much in guide or docs on the web. I'm currently using a sleep because my boot disk is about 20Gb in size and I know that in less than 2 minutes it normally completes. The export as ova is very similar to what found in the examples and they don't contain a monitor for it but only the connection.close() call: cloned_vm_service.export_to_path_on_host( host=types.Host(id=host.id), directory = export_as_ova_dir, filename = cloned_vm.name + '.ova' ) Thanks in advance, Gianluca

EqualLogic SAN controller switchover
by Chris Adams 27 Feb '20

27 Feb '20

How well does oVirt handle an EqualLogic SAN controller switchover event? IIRC that can result in a short iSCSI "pause" (can't remember how long it takes) - I'm not sure what oVirt's threshold before VMs (including the hosted engine) get paused for storage timeouts. I've got a small setup where the active SAN controller's battery has gone bad, so I need to switch to the other controller, and I'm trying to figure out the impact - do I need to shut all VMs (including the engine) down first, will they just briefly pause and then continue, etc. -- Chris Adams <cma(a)cmadams.net>

oVirt 4.3.8 ovn vms doesn't ping
by Gianluca Cecchi 27 Feb '20

27 Feb '20

Hello, I have an environment with oVirt 4.3.8. All seems ok from a configuration point of view, but if I use OVN based interfaces on two VMs, they are not able to ping, both if I put them on the same host and if I put on different hosts. At this point they are both running on the same host and their only vnic is on ovn172 network (defined as 192.168.172.0/24). I have this manager # ovn-nbctl show switch fc2fc4e8-ff71-4ec3-ba03-536a870cd483 (ovirt-ovn192-1e252228-ade7-47c8-acda-5209be358fcf) switch 87012fa6-ffaa-4fb0-bd91-b3eb7c0a2fc1 (ovirt-ovn193-d43a7928-0dc8-49d3-8755-5d766dff821a) port 8141047d-10c0-41f6-bedc-130552a115ef addresses: ["00:1a:4a:17:01:54 dynamic"] port 90559419-cb8e-45ae-ad61-6c16c4aff598 addresses: ["00:1a:4a:17:01:52 dynamic"] port b3db190f-086a-4c79-99a0-77f811f66c80 addresses: ["00:1a:4a:17:01:53 dynamic"] switch 9e77163a-c4e4-4abf-a554-0388e6b5e4ce (ovirt-ovn172-4ac7ba24-aad5-432d-b1d2-672eaeea7d63) port 3641cae4-18df-4fba-a2bd-7b0c60a87162 addresses: ["00:1a:4a:19:01:59 dynamic"] port aaddc425-3a38-49bf-bfc7-9eaeab82906e addresses: ["00:1a:4a:19:01:58 dynamic"] The two macs correspond to what I see for VMs in web admin gui and at os level of the two VMs. On the host where VMs are running I have: # ovs-vsctl show f1a41e9c-16fb-4aa2-a386-2f366ade4d3c Bridge br-int fail_mode: secure Port "ovn-b8872a-0" Interface "ovn-b8872a-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.34"} Port br-int Interface br-int type: internal Port "vnet0" Interface "vnet0" Port "ovn-1dce5b-0" Interface "ovn-1dce5b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.32"} Port "vnet1" Interface "vnet1" ovs_version: "2.11.0" So apparently I see the vnet0 and vnet1 ports associated with the two VMs How can I check more in depth the reason why they don't ping? Both VMs are CentOS 8.1 but I don't know if it is relevant. Thanks, Gianluca

oVirt 4.3.8 and almost unpredictable export as ova duration
by Gianluca Cecchi 27 Feb '20

27 Feb '20

Hello, on a test oVirt environment I have export as ova task that, based on same disk size (20Gb) it could last 35 seconds or 11 minutes.... During the long lasting test I see on host that almost all and only I/O (in the measure of 6-7 MB/s) is done by a [loop0] process that has ppid 2 and apparently (with "fuser" command on /dev/loop0 file) is uses by noone. Is it implicitly used by the "qemu-img convert " command of the export as ova? Why so great difference in elapsed time? The disk is the same of the same VM. The oVirt env has almost nothing running only 2 CentOS 8.1 VMs doing nothing. Same host used for export as ova in the two runs in a 20 minutes timeframe. As the path for OVA I'm temporarily using a connected export domain subdirectory, using directory='/rhev/data-center/mnt/10.4.192.69:_export_ovirt/dump' Donna if it can have a role in the problem... Thanks, Gianluca

Re: Huge increase of CPU load on hosted engine VM after upgrade to 4.3.8 and cluster compatibility version
by Florian Schmid 27 Feb '20

27 Feb '20

Hi, no, fortunately, the bug didn't came back. It looks like, that the engine needs its time to settle after changing the cluster compatibility version. After about 2 hours, the CPU load was as low as before. The time to load the VM UI takes a little bit more time, but I think this is also normal, because all VMs still have the orange triangle and need a reboot. Sorry for the false positive, but I was really afraid about the high load.

Hi, I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8. We have a hosted engine, 25 hosts and about 150 VMs running there. After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen a huge increase of CPU load on the engine VM. The engine had 4 cores (16GB mem) and never had load issues, but after the upgrade, the system has a load of 6 and more. I have increased the CPUs to 8, because working in the UI was impossible. I have noticed, that the load always increase, when I load the VM UI tab, where now all VMs have the orange triangle with pending changes: Custom compatibility version The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 4 weeks. Working now with the UI is quite problematic, because of the slowness. The engine VM was already rebooted, but didn't solve the problem. What logs do you need and is there a workaround available? I have some more oVirt environments to upgrade, all with even more VMs. BR Florian _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: [ https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt… | https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt… ] oVirt Code of Conduct: [ https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt… | https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt… ] List Archives: [ https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ovi… | https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.ovi… ] To view the terms under which this email is distributed, please go to:- [ http://leedsbeckett.ac.uk/disclaimer/email/ | http://leedsbeckett.ac.uk/disclaimer/email/ ]

Storage performance comparison (gluster vs FC)
by Rik Theys 26 Feb '20

26 Feb '20

Hi, We currently use oVirt on two hosts that connect to a shared storage using SAS. In oVirt this is a "FC" storage domain. Since the warrantly on the storage box is ending, we are looking at alternatives. One of the options would be to use gluster and use a "hyperconverged" setup where compute and gluster are on the same hosts. We would probably end up with 3 hosts and a "replica 3 arbiter 1" gluster volume. (Or is another volume type more recommended for this type of setup?) I was wondering what the expected performance would be of this type of setup compared to a shared storage over FC. I expect the I/O latency of gluster to be much higher than the latency for the SAS connected storage box? Has anybody compared these storage setups?

oVirt 4.3.8 spice console not working after vm migration
by Gianluca Cecchi 26 Feb '20

Hello, I'm registering problems with spice console session that remains stuck and not working after vm migration. Tried with 7.6 and 8.1 based virtual machines. The client is an updated Fedora 31 system. Using lsof -Pp pid command I don't see any tcp sessione opened Making the same when session is connected before migration: remote-vi 8013 g.cecchi 21u IPv4 243582 0t0 TCP localhost.localdomain:35218->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 22u IPv4 248960 0t0 TCP localhost.localdomain:35226->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 23u IPv4 248961 0t0 TCP localhost.localdomain:35228->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 24u IPv4 248962 0t0 TCP localhost.localdomain:35230->10.4.192.32:5902 (ESTABLISHED) Right after migration I see only the close wait of the previous but not a new one with the ip of the destination host: remote-vi 8013 g.cecchi 21u IPv4 243582 0t0 TCP localhost.localdomain:35218->10.4.192.32:5902 (CLOSE_WAIT) And after a few seconds none. Also, closing the blocked spice window doesn't work: it becomes gray with in the middle "Waiting for display 1..." and I have to "kill -9 the remote-viewer process. Strangely the reverse works.

Re: Damaged hard disk in volume replica gluster
by Strahil 25 Feb '20

25 Feb '20

As you are replacing an old brick, you have to recreate the old LV and mount it on the same location. Then you can use the gluster's "reset-brick" (i thing ovirt UI has that option too) and all data will be replicated there. You got also the "replace-brick" option if you decided to change the mount location. P.S.: with replica volumes your volume should be still working, in case it has stopped - you have to investigate before proceeding.

HostedEngine Upgrade and Rollback
by jrbdeguzman05＠gmail.com 25 Feb '20

25 Feb '20

Hi Everyone, Our HostedEngine is previously running in version 4.3.7 then updated it to 4.3.8. Before the update, we did a full backup of the HE. After a successful update, we're testing to roll it back to the previous backup. The cluster setting has been rolled back but the Hosted version is still 4.3.8. Is there a best way to rollback a HostedEngine after a successful minor update? I've read somewhere that if an upgrade / update is unsuccessful, HostedEngine will be rolled back to the previous version automatically. Thanks in advance.

oVirt ansible backup improvements
by Jayme 25 Feb '20

25 Feb '20

If anyone has been following along, I had previously shared a blog post and GitHub repo regarding my unofficial solution for backing up oVirt VMs using Ansible. Martin Necas reached out to me and we collaborated on some great improvements. Namely, it is now possible to run the playbook from any host without requiring direct access to storage (which I was previously using for export status verification). There were several other improvements and cleanups made as well. The changes have been merged in and the READMME updated, you can find the project here: https://github.com/silverorange/ovirt_ansible_backup Big thanks to Martin for helping out. Very much appreciated! - Jayme

Dashboard very slow to load: change default page possible?
by Gianluca Cecchi 25 Feb '20

25 Feb '20

Hi, I'm noticing that after upgrading to 4.3.8, sometimes the dashboard is very slow and it takes minutes to display and to let me work, even if I'm not interested at all to the dashboard for the activities I have to do. As a consequence it becomes a bottleneck. On engine I see that during these moments the postmaster process related to ovirt_engine_history database is 100% cpu consuming. Almost every minor update I run vacuum but I don't know if there is something else involved. Is there any bug open with in in 4.3.8? Is there any option to set another page as the landing one when I open web admin portal? I have similar problem on a RHV environment where I have done upgrade form 4.2.7 to 4.2.8 and then 4.3.8 in the same day (eventually I'm going to open a case fir this one). When passing from 4.2.7 to 4.2.8 I chose full vacuum for the engine history database: Perform full vacuum on the oVirt engine history database ovirt_engine_history@localhost? This operation may take a while depending on this setup health and the configuration of the db vacuum process. See https://www.postgresql.org/docs/9.0/static/sql-vacuum.html (Yes, No) [No]: Yes while I chose NO during the upgrade from 4.2.8 to 4.3.8 that I've done half an hour later. Thanks in advance, Gianluca

IO Storage Error / All findings / Need help.
by Christian Reiss 24 Feb '20

24 Feb '20

Hello folks, I am running a 3-way, no arbiter Gluster setup using oVirt and contained Gluster 6.7. After a crash we are unable to start any VMs due to Storage IO error. After much, much backtracking and debugging we are closing in on the symptons, albeit not the issue. Conditions: - gluster volume is healthy, - No outstanding heal or split-brain files, - 3 way without arbiter nodes (3 copies), - I already ran several "heal full" commands. Gluster Volume Info Volume Name: ssd_storage Type: Replicate Volume ID: d84ec99a-5db9-49c6-aab4-c7481a1dc57b Status: Started Snapshot Count: 0 Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: node01.company.com:/gluster_bricks/ssd_storage/ssd_storage Brick2: node02.company.com:/gluster_bricks/ssd_storage/ssd_storage Brick3: node03.company.com:/gluster_bricks/ssd_storage/ssd_storage Options Reconfigured: cluster.self-heal-daemon: enable cluster.granular-entry-heal: enable storage.owner-gid: 36 storage.owner-uid: 36 network.ping-timeout: 30 server.event-threads: 4 client.event-threads: 4 cluster.choose-local: off user.cifs: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: off performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off performance.strict-o-direct: on transport.address-family: inet nfs.disable: on performance.client-io-threads: on Gluster Volume Status Status of volume: ssd_storage Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick node01.company.com:/gluster_br icks/ssd_storage/ssd_storage 49152 0 Y 8218 Brick node02.company.com:/gluster_br icks/ssd_storage/ssd_storage 49152 0 Y 23595 Brick node03.company.com:/gluster_br icks/ssd_storage/ssd_storage 49152 0 Y 8080 Self-heal Daemon on localhost N/A N/A Y 66028 Self-heal Daemon on 10.100.200.12 N/A N/A Y 52087 Self-heal Daemon on node03.company.com et N/A N/A Y 8372 Task Status of Volume ssd_storage ------------------------------------------------------------------------------ There are no active volume tasks The mounted path where the oVirt vm files reside is 100% okay, we copied all the images out there onto standalone hosts and the images run just fine. There is no obvious data corruption. However launching any VM out of oVirt fails with "IO Storage Error". This is where everything gets funny. oVirt uses a vdsm user to access all the files. Findings: - root can read, edit and write all files inside the ovirt mounted gluster path. - vdsm user can write to new files regardless of size without any issues; changes get replicated instantly to other nodes. - vdsm user can append to existing files regardless of size without any issues; changes get replicated instantly to other nodes. - vdsm user can read files if those files are smaller than 64mb. - vdsm user gets permission denied errors if the file to be read is 65mb or bigger. - vdsm user gets permission denied errors if the requests crosses a gluster shard-file boundary. - if root does a "dd if=file_larger_than64mb" of=/dev/null" on any large file, the file can then be read by the vdsm user on that single node. Changes do not get replicated to other nodes. Example: id of the vdsm user & sudo to them: [vdsm@node01:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ id uid=36(vdsm) gid=36(kvm) groups=36(kvm),107(qemu),179(sanlock) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [vdsm@node02:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ id uid=36(vdsm) gid=36(kvm) groups=36(kvm),107(qemu),179(sanlock) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [vdsm@node03:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ id uid=36(vdsm) gid=36(kvm) groups=36(kvm),107(qemu),179(sanlock) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 Create a file >64mb on one node: [vdsm@node03:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ base64 /dev/urandom | head -c 200000000 > file.txt [vdsm@node03:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ ls -lha total 191M drwxr-xr-x. 2 vdsm kvm 30 Feb 4 13:10 . drwxr-xr-x. 6 vdsm kvm 80 Jan 1 1970 .. -rw-r--r--. 1 vdsm kvm 191M Feb 4 13:10 file.txt File is instantly available on another node: [vdsm@node01:/rhev/data-center/mnt/glusterSD/node01.company.com:_ssd__storage/fec2eb5e-21b5-496b-9ea5-f718b2cb5556/test] $ ls -lha total 191M drwxr-xr-x. 2 vdsm kvm 30 Feb 4 13:10 . drwxr-xr-x. 6 vdsm kvm 80 Jan 1 1970 .. -rw-r--r--. 1 vdsm kvm 191M Feb 4 13:10 file.txt Accessing the whole file fails: [vdsm@node01:] dd if=file.txt of=/dev/null dd: error reading ‘file.txt’: Permission denied 131072+0 records in 131072+0 records out 67108864 bytes (67 MB) copied, 0.0651919 s, 1.0 GB/s Reading first 64mb works, 65mb (crossing boundary) does not: [vdsm@node01:] $ dd if=file.txt bs=1M count=64 of=/dev/null 64+0 records in 64+0 records out 67108864 bytes (67 MB) copied, 0.00801663 s, 8.4 GB/s [vdsm@node01:] $ dd if=file.txt bs=1M count=65 of=/dev/null dd: error reading ‘file.txt’: Permission denied 64+0 records in 64+0 records out 67108864 bytes (67 MB) copied, 0.00908712 s, 7.4 GB/s Attaching/ appending to the file works (not crossing bounary): [vdsm@node01:] $ date >> file.txt [vdsm@node01:] $ [vdsm@node02:] $ tail -n2 file.txt E16ACZaLqLhx2oUUUov5JHvQcVFohn6HH+eog6XZCiTaG0Tue 4 Feb 13:18:37 CET 2020 Reading the file beginning & end works, if it crosses the boundary not so much: [vdsm@node02:] $ head file.txt jrZOxGaGvwfpGSwn1BKWWmFC4556KNzXsD2BCwY78tnV1mRY54IxnE+hbnszRyWgVuXhBpVRoJTp xvVwktZwSytMyvJjsSt7pQbXbHSY66tRe/rvrw5dHr3RNJn9HjqtlKQ9mHVX4ch1HkU5posSmDbg vwzxBTXWfxLDMmIghyTgBTSFiI9Xg8W6htxDpxrbO+10EzlnaN1Am5tAlTkfrorNLyihpiQhUPGG ag6tJUcFj3IySGRTAxnStFRQoBXN5dlyx1Sqc4s/Tpl7gkgR8+I7UcdRKISjgcGcpW+zrXKqFF/H Dwv6ql+2ysPRrtlbt2V8Zf697VsNX5DTgZS9BKmWlAeqejNYaqG5Rsuhn7szbCfkkmsjedk+Rdcv A3SHMBeHXdtfBHS0AlbEwKgeml08NmCUcwnifhrQywCnu8NN9+RQ3cUxGvIuLLSzi3915wC6hbxr 8xArckQfSUfKA/hrHvoiiCGZU9D23xj3XXtsjdbIIDXATDnCPrKANdvGN5LTKal8bT0jXORfAz1z MniqVUgvWVNcviPgQ9BfT5qpGo8g7LaoBMGamAGVX6Ezrs04rk8jQ1yz1bB/8URfTRLZdyYkMh0u MB4xMylnyavgusoi7Duf5RuYJvNaL0g8Lx/cfGpGsGwdD2Lj/qRC45ammn6wCxDVfiJV6Z/TzJcY PBvzWK5xT++PQgMV8EwtXwA1kFqaGrcuiDHejMQ8O82Edjr+eBCBe0B7bRddoMD6oOlhNm1YsSNt [vdsm@node02:] $ tail file.txt 9JX8OWCJwbyvEPDyyI30H1/jPZfDo1sS11dZ2JjiO7qhB45VaU8+irG45D0GGJhFf8wE8TD9EGWG 8346QHLX9ZSFsbjpuh71hr5Ju1UduVdvIDwwP8WDBtRUbMAVvsyGR33rkpijepmUjmYl/jeZ7rsC VyUVlmG5PxrI7KKxz5dSkzApqVHKKgsf93JMDAdPwvXTq4hhZdUJ581w9FC/f9k2wWldEGkAcyB0 cCKp+VJl2vx989KUoqAJzsrvYdK0X7itruqYdpC29JXode+7NixUflhKvPdKmitBYyCEgCcyxUyn eyMOdaan2x8d8MztLLoWLpp+gLzl2Hev7y3OXq6I9SVN2t+hcVIz8Llmumy0cD+VC4u2/UZszYqS nDaSSMs35agGUUgIpHjPxCRf/yqnfrJJMTGAcxSEqHtpEdsjEmkf4QkyEgEZ13f4oi7P/DFCIIvV JBsHzOLDoetnFzAA2/RqbDflPrVWcAR7tXVqGLACCj2s19uUFSNb8nBWmEk8fFz31iJhuL43v0WE 78/THl49T0hhzHQp6kdIiw5p1zPUIFGBZ0BS4mBCHxu+tMlPZe1zWJMJZdPnvDNtHZ4gQ6LFgU4w E16ACZaLqLhx2oUUUov5JHvQcVFohn6HH+eog6XZCiTaG0Tue 4 Feb 13:18:37 CET 2020 [vdsm@node02:] $ dd if=file.txt of=/dev/null dd: error reading ‘file.txt’: Permission denied 131072+0 records in 131072+0 records out 67108864 bytes (67 MB) copied, 0.106097 s, 633 MB/s if root does dd first, all is peachy: [root@node02] # dd if=file.txt of=/dev/null 390625+1 records in 390625+1 records out 200000058 bytes (200 MB) copied, 0.345906 s, 578 MB/s [vdsm@node02] $ dd if=file.txt of=/dev/null 390625+1 records in 390625+1 records out 200000058 bytes (200 MB) copied, 0.188451 s, 1.1 GB/s Error in the gluster.log: [2020-02-04 12:27:57.915356] W [MSGID: 114031] [client-rpc-fops_v2.c:2634:client4_0_lookup_cbk] 0-ssd_storage-client-1: remote operation failed.

We are out of ideas and also no experts on either gluster nor ovirt, it seems. And this is supposed to be a production HA environment. Any help would be appreciated. I hope I did think of all the relevant data and logs. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

oVirt behavior with thin provision/deduplicated block storage
by Alan G 24 Feb '20

24 Feb '20

Hi, I have an oVirt cluster with a storage domain hosted on a FC storage array that utilises block de-duplication technology. oVirt reports the capacity of the domain as though the de-duplication factor was 1:1, which of course is not the case. So what I would like to understand is the likely behavior of oVirt when the used space approaches the reported capacity. Particularly around the critical action space blocker. Thanks, Alan

New Host Migration Failure & Console Failure

24 Feb '20

Good Day I have installed new oVirt platform with hosted engine, but when I add a new host, the notification keeps repeating "Finished Activating Host" and it does not stop until I select do not disturb for 1 day. (Screenshot attached) Also once the new host has been added, I am unable to migrate a VM to it, if I start a VM up on the new host, I am unable to migrate the VM away from it or launch a console. Please see the following logs from when I tried to migrate a VM to the new host. 2020-02-19 09:48:27,034Z INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (default task-55) [0de8c750-2955-40f3-ab75-a33d29894199] Running command: MigrateVmToServerCommand internal: false.
