Re: Certificate of host is invalid
by Strahil 04 Dec '19

Hi , You can try with: 1. Set the host in maintenance 2. From Install dropdown , select 'reinstall' and then configure the necessary info + whether you would like to use the host as Host for the HostedEngine VM. Once the reinstall (of Ovirt software) is OK, the node will be activated automatically.

Disk move succeed but didn't move content
by Juan Pablo Lorier 03 Dec '19

03 Dec '19

Hi, I've a fresh new install of ovirt 4.3 and tried to import an gluster vmstore. I managed to import via NFS the former data domain. The problem is that when I moved the disks of the vms to the new ISCSI data domain, I got a warning that sparse disk type will be converted to qcow2 disks, and after accepting, the disks were moved with no error. The problem is that the disks now figure as <1Gb size instead of the original size and thus, the vms fail to start. Is there any way to recover those disks? I have no backup of the vms :-( Regards

Current status of Ceph support in oVirt (2019)?
by victorhooi＠yahoo.com 03 Dec '19

03 Dec '19

Hi, I currently have a 3-node HA cluster running Proxmox (with integrated Ceph). oVirt looks pretty neat, however, and I'm excited to check it out. One of the things I love about Proxmox is the integrated Ceph support. I saw on the mailing lists that there is some talk of Ceph support earlier, but it was via OpenStack/Cinder. What exactly does this mean? 1. Does this require you to install OpenStack, or will a vanilla Ceph installation work? 2. Is it possible to deploy Ceph on the same nodes that run oVirt? (i.e. is a 3-node oVirt + Ceph cluster possible?) 3. Is there any monitoring/management of Ceph from within oVirt? (Guessing no?) 4. Are all the normal VM features working yet, or is this planned? 5. Is making Ceph a first-class citizen (like Gluster) on oVirt on the roadmap? Thanks, Victor https://www.reddit.com/r/ovirt/comments/ci38zp/ceph_rbd_support_in_ovirt_fo…

oVirt nodes not responding
by Tim Herrmann 03 Dec '19

03 Dec '19

Hi everyone, we have an oVirt-Cluster with 5 nodes and 3 of them provide the storage with GlusterFS and replica 3. The cluster is running 87 VMs and has 9TB storage where 4TB is in use. The version of the oVirt-Engine is 4.1.8.2 and GlusterFS is 3.8.15. The servers are running in a HP bladecenter and are connected with 10GBit to each other. Actually we have some problems that all ovirt nodes periodically won't respond in the cluster with the following error messages in the oVirt webinterface: VDSM glustervirt05 command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues Host glustervirt05 is not responding. It will stay in Connecting state for a grace period of 68 seconds and after that an attempt to fence the host will be issued. Host glustervirt05 does not enforce SELinux. Current status: PERMISSIVE Executing power management status on Host glustervirt05 using Proxy Host glustervirt02 and Fence Agent ilo4:xxx.xxx.xxx.xxx. Manually synced the storage devices from host glustervirt05 Status of host glustervirt05 was set to Up. In the vdsm logfile I can find the following message: 2019-11-26 11:18:22,909+0100 WARN (vdsm.Scheduler) [Executor] Worker blocked: <Worker name=jsonrpc/7 running <Task <JsonRpcTask {'params': {u'volumeName': u'data'}, 'jsonrpc': '2.0', 'method': u'GlusterVolume.healInfo', 'id': u'2e86ed2c- 3e79-42c1-a7e4-c09bfbfc7794'} at 0x7fb938373190> timeout=60, duration=180 at 0x316a6d0> task#=2859802 at 0x1b70dd0> (executor:351) And I figured out, that the gluster heal info command takes very long: [root@glustervirt01 ~]# time gluster volume heal data info Brick glustervirt01:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt02:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt03:/gluster/data/brick2 Status: Connected Number of entries: 0 real 3m3.626s user 0m0.593s sys 0m0.559s A strange behavier is also that there is one virtual machine (a postgresql database) which stops running unexpectedly every one or two days ... The only thing that has been changed on the vm in the least past was a resize of the disk. VM replication-zabbix is down with error. Exit message: Lost connection with qemu process. And when we add or delete a larger disk with approximately 100GB in glusterfs, the glusterfs cluster freaks out won't respond anymore. This also results in paused VMs ... Has anyone an idea what could cause such problems?

Overt Networking VM not pinging
by Vijay Sachdeva 02 Dec '19

02 Dec '19

Dear Community, I have installed Ovirt Engine 4.3 and Ovirt Node 4.3. Node got successfully added to engine and setup host network also done. When trying to ping host using “ovirtmgmt” as vNic profile for a VM, it is not even able to ping it’s host or any other machine on that same network. Also added a VLAN network which is passed via same uplink of Node interface where “Ovirtmgmt” is passed, that is also not working. Although this vnet is vnic type is VirtIO and state shows “UNKNOWN”, would this be a problem? Any help would be highly appreciated.

hyperconverged single node with SSD cache fails gluster creation
by thomas＠hoberg.net 01 Dec '19

01 Dec '19

I am seeing more success than failures at creating single and triple node hyperconverged setups after some weeks of experimentation so I am branching out to additional features: In this case the ability to use SSDs as cache media for hard disks. I tried first with a single node that combined caching and compression and that fails during the creation of LVMs. I tried again without the VDO compression, but actually the results where identical whilst VDO compression but without the LV cache worked ok. I tried various combinations, using less space etc., but the results are always the same and unfortunately rather cryptic (substituted the physical disk label with {disklabel}): TASK [gluster.infra/roles/backend_setup : Extend volume group] ***************** failed: [{hostname}] (item={u'vgname': u'gluster_vg_{disklabel}p1', u'cachethinpoolname': u'gluster_thinpool_gluster_vg_{disklabel}p1', u'cachelvname': u'cachelv_gluster_thinpool_gluster_vg_{disklabel}p1', u'cachedisk': u'/dev/sda4', u'cachemetalvname': u'cache_gluster_thinpool_gluster_vg_{disklabel}p1', u'cachemode': u'writeback', u'cachemetalvsize': u'70G', u'cachelvsize': u'630G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Physical volume \"/dev/mapper/vdo_{disklabel}p1\" still in use\n", "item": {"cachedisk": "/dev/sda4", "cachelvname": "cachelv_gluster_thinpool_gluster_vg_{disklabel}p1", "cachelvsize": "630G", "cachemetalvname": "cache_gluster_thinpool_gluster_vg_{disklabel}p1", "cachemetalvsize": "70G", "cachemode": "writeback", "cachethinpoolname": "gluster_thinpool_gluster_vg_{disklabel}p1", "vgname": "gluster_vg_{disklabel}p1"}, "msg": "Unable to reduce gluster_vg_{disklabel}p1 by /dev/dm-15.", "rc": 5} somewhere within that I see something that points to a race condition ("still in use"). Unfortunately I have not been able to pinpoint the raw logs which are used at that stage and I wasn't able to obtain more info. At this point quite a bit of storage setup is already done, so rolling back for a clean new attempt, can be a bit complicated, with reboots to reconcile the kernel with data on disk. I don't actually believe it's related to single node and I'd be quite happy to move the creation of the SSD cache to a later stage, but in a VDO setup, this looks slightly complex to someone without intimate knowledge of LVS-with-cache-and-perhaps-thin/VDO/Gluster all thrown into one. Needless the feature set (SSD caching & compressed-dedup) sounds terribly attractive but when things don't just work, it's more terrifying.

Moving HostedEngine
by Joseph Goldman 28 Nov '19

28 Nov '19

Hi List, In one of my installs, I set up the first storage domain (and where the HostedEngine is) on a bigger NFS NAS - since then I have created a Gluster volume that spans the 3 hosts and I'm putting a few VM's in there for higher reliability (as SAN is single point of failure) namely I'd like to put HostedEngine in there so it stays up no matter what and can help report if issues occur (network issue to NAS, NAS dies etc etc) Looking through other posts and documentation, there's no real way to move the HostedEngine storage, is this correct? The solution I've seen is to backup the hosted engine DB, blow it away, and re-deploy it from the .backup file configuring it to the new storage domain in the deploy script - is this the only process? How likely is this to fail? Is it likely that all VM's and settings will be picked straight back up and continue to operate like normal? I dont have a test setup to play around with atm so just trying to gauge confidence in such a solution. Thanks, Joe

Re: HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7
by Strahil 28 Nov '19

28 Nov '19

The HostedEngine does it automatically, but the option that defines the OVF refresh interval is not accurate. Just power it up without that option (cluster in maintenance) and keep it running for a day. On the next day power it off and try to power it up via hosted-engine --vm-start.

Check on host 'node3' in the Network configuration if you have a network out of sync or any clues about the error .
