Disk sizes not updated on unmap/discard
by Tomáš Golembiovský 02 Oct '20

02 Oct '20

Hi, currently, when we run virt-sparsify on VM or user runs VM with discard enabled and when the disk is on block storage in qcow, the results are not reflected in oVirt. The blocks get discarded, storage can reuse them and reports correct allocation statistics, but oVirt does not. In oVirt one can still see the original allocation for disk and storage domain as it was before blocks were discarded. This is super-confusing to the users because when they check after running virt-sparsify and see the same values they think sparsification is not working. Which is not true. It all seems to be because of our LVM layout that we have on storage domain. The feature page for discard [1] suggests it could be solved by running lvreduce. But this does not seem to be true. When blocks are discarded the QCOW does not necessarily change its apparent size, the blocks don't have to be removed from the end of the disk. So running lvreduce is likely to remove valuable data. At the moment I don't see how we could achieve the correct values. If anyone has any idea feel free to entertain me. The only option seems to be to switch to LVM thin pools. Do we have any plans on doing that? Tomas [1] https://www.ovirt.org/develop/release-management/features/storage/pass-disc… -- Tomáš Golembiovský <tgolembi(a)redhat.com>

Incremental Backup | oVirt
by luwen.zhang＠vinchin.com 30 Sep '20

30 Sep '20

Dear team, My name is Luwen Zhang from Vinchin Backup & Recovery. I'm sending you this Email because our developers encountered some problems while developing incremental backup feature following the oVirt documentations. https://www.ovirt.org/documentation/incremental-backup-guide/incremental-ba… We downloaded oVirt 4.4.1 from oVirt website, and is now developing based on this version, as per the documentation when we perform the first time full backup, we should obtain a "checkpoint id", so when we perform incremental backup using this ID we should know what's have changed on the VM. But now the problem is that we cannot get the checkpoint ID. The components and versions of oVirt are as follows: Could you please kindly check on this issue and point out what should be wrong and what we should do? Looking forward to your reply. Thanks & regards!

Propose Eitan Raviv as a ovirt-system-tests network-suite maintainer
by Dominik Holler 28 Sep '20

28 Sep '20

Hi all, Eitan Raviv has been working on the oVirt project for more than 3 years. He contributed more than 40 patches to ovirt-system-tests, including more than 35 patches to the network-suite. He is already recognized as a relevant reviewer for the network-suite, so it time to give him the official role for the work he is already doing. I would like to propose Eitan as a virt-system-tests network-suite maintainer. Thanks Dominik

Upgrade to 4.4 does not describe how to handle Gluster brick migration
by Sandro Bonazzola 23 Sep '20

23 Sep '20

Hi, it has been reported to oVirt website on https://github.com/oVirt/ovirt-site/issues/2287 that we may improve upgrade documentation covering (or linking to existing documentation) the gluster brick migration from el7 to el8 while upgrading from 4.3 to 4.4. Have we already got something we can provide there?

Very slow push/pull to/from gerrit
by Nir Soffer 23 Sep '20

23 Sep '20

Recently pushing changes to gerrit is very slow. It seems that the issue is pulling changes during rebase in "git review". Sometimes "git review" is very slow, but "git review -R" is very quick. This show that the issue was getting changes from gerrit during when git-review try to rebase the current branch on master. I noticed that origin/master and gerrit/master do not show the same commit: $ git log origin/master | head -1 commit 6e6e93cb1d237f9b6fdd533d5afdc1b9ba1c197a $ git log gerrit/master | head -1 commit 353e7b1e322aa02d4767b6617ed094be0643b094 $ git remote -v gerrit http://gerrit.ovirt.org/p/vdsm.git (fetch) gerrit ssh://nsoffer@gerrit.ovirt.org:29418/vdsm.git (push) origin http://gerrit.ovirt.org/p/vdsm.git (fetch) origin http://gerrit.ovirt.org/p/vdsm.git (push) I've been using this configuration for several years, and the slowness started only recently, so I guess the issue is not on my side. Same issues also on ovirt-engine, using similar configuration: $ git remote -v gerrit http://gerrit.ovirt.org/ovirt-engine (fetch) gerrit ssh://nsoffer@gerrit.ovirt.org:29418/ovirt-engine.git (push) origin git://gerrit.ovirt.org/ovirt-engine (fetch) origin git://gerrit.ovirt.org/ovirt-engine (push) Anyone experienced this? I guess that restarting the gerrit server will "fix" this issue. Nir

Hello, Localizator/translator here :) I have a small question regarding the cockpit-ovirt utility[1]. Are there any plans of adding the i18n into the code to facilitate proper translation of cockpit-ovirt? Thank you!
