Move self hosted engine to a different gluster volume
by ralf＠os-s.de 17 Dec '20

17 Dec '20

Hi, I apparently successfully upgraded a hyperconverged self hosted setup from 4.3 to 4.4. During this process the selfhosted engine required a new gluster volume (/engine-new). I used a temporary storage for that. Is it possible to move the SHE back to the original volume (/engine)? What steps would be needed? Could I just do: 1. global maintenance 2. stop engine and SHE guest 3. copy all files from glusterfs /engine-new to /engine 4. use hosted-engine --set-shared-config storage <server1>:/engine hosted-engine --set-shared-config mnt_options backup-volfile-servers=<server2>:<server3> 5. disable maintenance Or are additional steps required? Kind regards, Ralf

Increase the initial size of LVM snapshots to prevent VM's from freezing
by Gal Villaret 16 Dec '20

16 Dec '20

Hi all, Lately, I have been encountering an issue where VMs freeze during backups. From what I can gather, this happens because some of the VMs sometimes perform large writes during the backup window and the snapshots dose not grow fast enough. I use ISCSI storage with all VM disks preallocated. Is there a configuration value I can change in order to increase the initial size of snapshots and also maybe change the watermark trigger for the expansion of snapshots? Thanks.

Bad CPU TYPE after Centos 8.3
by Lionel Caignec 15 Dec '20

15 Dec '20

Hi, i've just upgraded one host to latest centos release. And after reboot ovirt said "Host CPU type is not compatible with Cluster Properties." Looking on server i can see cpu is detected as skylake (cat /sys/devices/cpu/caps/pmu_name). My CPU is Intel(R) Xeon(R) Gold 5220R CPU @ 2.20GHz so according to ark cascade lake server. When i installed my new ovirt environment month agos, i configure cluster to be "secure Intel Cascade lake server family" and all sound goods. So anyone can help me? Environment : OS : Centos 8.3 (for manager and host in error) ovirt-engine 4.4.3.12-1.el8 Host with error : vdsm.x86_64 4.40.35.1-1.el8 Working Host : vdsm.x86_64 .40.26.3-1.el8 Maybe someone can help me? I don't know what to do, and does not want to try update another host if it fail... Sorry if i post my message at wrong place. Lionel Caignec.

How to unlock disk images?
by thomas＠hoberg.net 15 Dec '20

15 Dec '20

On one oVirt 4.3 farm I have three locked images I'd like to clear out. One is an ISO image, that somehow never completed the transfer due to a slow network. It's occupying little space, except in the GUI where it sticks out and irritates. I guess it would just be an update somewhere on the Postgress database to unlock it and have it deletable: But since the schema isn't documented, I'd rather ask here: How to I unlock the image? Two are left-overs from a snapshot that somehow never completed, one for the disk another for the RAM part. I don't know how my colleague managed to get into that state, but impatience/concurrency probably was a factor, a transient failure of a node could have been another. In any case the snapshot operation logically has been going on for weeks without any real activity, survived several restarts (after patches) of all nodes and the ME and shows no sign of disappearing voluntarily. Again, I'd assume that I need to clear out the snapshot job, unlock the images and then delete what's left. Some easy SQL and most likely a management engine restart afterwards... if you knew what you were doing (or there was an option in the GUI). So how do I list/delete snapshot jobs that aren't really running any more? And how do I unlock the images so I can delete them? Thanks for your help!

illegal disk status
by Daniel Menzel 15 Dec '20

15 Dec '20

Hi, we have a problem with some VMs which cannot be started anymore due to an illegal disk status of a snapshot. What happend (most likely)? we tried to snapshot those vms some days ago but the storage domain didn't have enough free space left. Yesterday we shut those vms down - and from then on they didn't start anymore. What have I tried so far? 1. Via the web interface I tried to remove the snapshot - didn't work. 2. Searched the internet. Found (among other stuff) this: https://bugzilla.redhat.com/show_bug.cgi?id=1649129 3. via /vdsm-tool dump-volume-chains/ I managed to list those 5 snapshots (see below). The output for one machine was: image: 2d707743-4a9e-40bb-b223-83e3be672dfe - 9ae6ea73-94b4-4588-9a6b-ea7a58ef93c9 status: OK, voltype: INTERNAL, format: RAW, legality: LEGAL, type: PREALLOCATED, capacity: 32212254720, truesize: 32212254720 - f7d2c014-e8f5-4413-bfc5-4aa1426cb1e2 status: ILLEGAL, voltype: LEAF, format: COW, legality: ILLEGAL, type: SPARSE, capacity: 32212254720, truesize: 29073408 So my idea was to follow the said bugzilla thread and update the volume - but I didn't manage to find input for the /job_id/ and /generation/. So my question is: Does anyone have an idea on how to (force) remove a given snapshot via vsdm-{tool|client}? Thanks in advance!

Re: CentOS 8 is dead

So, I think keep the live system on ovirt 4.3 to be sure that's works after 2021? Distribution you have 10 years support? Centos 7 has support up to June 24.
