Is it fsfreeze the command executed at VM OS level or any other low level command? It’s a matter of Linux and Windows implementation, they both have an API supporting that at kernel level. I’m not aware of filesystem limitations. If you use Windows and the qemu-ga, it'd call VSS, which, if supported by applications (ranging from Notepad to SQL server) will provide application consistent snapshot. Y.

iSCSI LUN recommended sector size

Hosted engine already imported
by Jamie Lawrence 04 May '17

04 May '17

Hi all, In my hopefully-near-complete quest to automate Ovirt configuration in our environment, I’m very close. One outstanding issue that remains is that, even though the hosted engine storage domain actually was imported and shows in the GUI, some part of Ovirt appears to think that hasn’t happened yet. In the GUI, a periodic error is logged: “The Hosted Engine Storage Domain doesn’t exist. It will be imported automatically…” In engine.log, all I’m seeing that appears relevant is: 2017-04-25 10:28:57,988-07 INFO [org.ovirt.engine.core.bll.storage.domain.ImportHostedEngineStorageDomainCommand] (org.ovirt.thread.pool-6-thread-9) [1e44dde0] Lock Acquired to object 'EngineLock:{exclusiveLocks='[]', sharedLocks='null'}' 2017-04-25 10:28:57,992-07 WARN [org.ovirt.engine.core.bll.storage.domain.ImportHostedEngineStorageDomainCommand] (org.ovirt.thread.pool-6-thread-9) [1e44dde0] Validation of action 'ImportHostedEngineStorageDomain' failed for user SYSTEM. Reasons: VAR__ACTION__ADD,VAR__TYPE__STORAGE__DOMAIN,ACTION_TYPE_FAILED_STORAGE_DOMAIN_ALREADY_EXIST 2017-04-25 10:28:57,992-07 INFO [org.ovirt.engine.core.bll.storage.domain.ImportHostedEngineStorageDomainCommand] (org.ovirt.thread.pool-6-thread-9) [1e44dde0] Lock freed to object 'EngineLock:{exclusiveLocks='[]', sharedLocks='null’}’ Otherwise the log is pretty clean. I saw nothing of interest in the Gluster logs or the hosted-engine-ha logs on the host it is running on. It appears harmless, but then we aren’t actually using these systems yet, and in any case we don’t want the error spamming the log forever. This is 4.1.1.8-1.el7.centos, hosted engine on Centos 7.6.1311, Gluster for both the hosted engine and general data domains. Has anyone seen this before? Thanks in advance, -j

New oVirt Node 4.0.6.1 network problem with bond and many vlans - Network.service timeout failed
by Rogério Ceni Coelho 04 May '17

04 May '17

Hi oVirt admins, Yesterday, i install a new node 4.0.6.1 and after config network bond (1) + vlans ( about 50 ), network.service failed with timeout as above. All my old and working fine oVirt nodes run 4.0.5 and have the same 5 min timeout on systemd. When i try to run vms on this new server, some networks are ok and some not. I install oVirt Node with 4.0.3 on same server and this problem do not occur. How can i workaround or change timeout to network.service ? In time, there are any way to update oVirt Node to 4.0.5 from 4.0.3 install iso ?

configuring gluster volumes/bricks from ovirt ??
by Matthias Leopold 04 May '17

04 May '17

hi, i'm trying to get into this gluster thing with oVirt and added a 2 node gluster cluster to my oVirt 4.1 data center (just for testing, i know it can't have HA with 2 nodes). provisioning of the storage hosts did apparently work and my storage cluster seems to be operational. i have very little understanding of glusterfs right know, but what i think i am missing in the interface is a way to configure volumes/bricks on my gluster cluster/hosts so i can use them for storage domains (i want to use a "managed gluster volume"), the drop down "Gluster" in "New domain" is empty. all i could find for storage specific UI was the "Services" tab for the storage cluster which is empty. i'm not using a hyperconverged/self-hosted setup, my engine is located on a dedicated server and i used iSCSI storage for data master domain. my hosts (for hypervisors and gluster storage) where installed on top of centos7, not using oVirt Node. does my setup make sense (it's only for testing)? do i have to configure gluster hosts manually? do i need more than 2 storage hosts when i want to configure gluster with ovirt (in hyperconverged setup 3 hosts are mandatory)? do i need oVirt Node/cockpit on the storage hosts to do further configuration? thanks a lot for reading matthias

Ovirt tasks "stuck"
by Jim Kusznir 04 May '17

04 May '17

Hi: A few days ago I attempted to create a new VM from one of the ovirt-image-repository images. I haven't really figured out how to use this reliably yet, and in this case, while trying to import an image, one of my nodes spontaneously rebooted (or at least, it looked like that to ovirt...Not sure if it had an OOM issue or something else). I assume it was the node that got the task of importing those images, as ever since then (several days now), on my management screen under "Tasks" it shows the attempted imports, still stuck in "processing". I'm quite certain its not actually processing. I do believe it used some of my storage up in the partially downloaded images, though (they do show up as GlanceDisk-<numbers>, with a status of "Locked" under the main Disks tab. How do I "properly" recover from this (abort the task and delete the partial download)? Thanks! --Jim

collectd, fluentd, ...
by Troels Arvin 04 May '17

04 May '17

Hello, Setup: RHV 4.1 with full RHEL 7 servers as hypervisor hosts. I noticed an "Update available" symbol for all the hypervisor hosts. Running "yum update" on the hosts themselves didn't list any pending updates. Running "check for available updates" on the hosts in the RHV web interface resulted in a long list of software which RHV would like to add, it seems, see below. What's all that, and is it really needed? The packages: found updates for packages collectd-5.7.0-4.el7, collectd- disk-5.7.0-4.el7, collectd-netlink-5.7.0-4.el7, collectd- virt-5.7.0-4.el7, collectd-write_http-5.7.0-4.el7, fluentd-0.12.29-1.el7, libcollectdclient-5.7.0-4.el7, ruby-2.0.0.648-29.el7, ruby- irb-2.0.0.648-29.el7, ruby-libs-2.0.0.648-29.el7, rubygem- bigdecimal-1.2.0-29.el7, rubygem-cool.io-1.4.5-2.el7, rubygem-fluent- plugin-rewrite-tag-filter-1.5.5-3.el7, rubygem-fluent-plugin-secure- forward-0.4.3-2.el7, rubygem-http_parser.rb-0.6.0-3.el7, rubygem-io- console-0.4.2-29.el7, rubygem-json-1.7.7-29.el7, rubygem- msgpack-0.5.12-2.el7, rubygem-proxifier-1.0.3-2.el7, rubygem- psych-2.0.0-29.el7, rubygem-rdoc-4.0.0-29.el7, rubygem-resolve- hostname-0.0.4-1.el7, rubygem-sigdump-0.2.4-1.el7, rubygem-string- scrub-0.0.5-3.el7, rubygem-thread_safe-0.3.5-2.el7, rubygem- tzinfo-1.2.2-3.el7 -- Regards, Troels Arvin, Copenhagen
