[ovirt-users] Snapshots and mess with Storage

[thorsten.bolten--- via Users]

Hi,

I experienced a weird Failure. I hope I explain it understandable and not too 
hard to read

We had issues with our backups, that they can't finalize
Here is a Thread someone having the same issue.

https://forums.veeam.com/ovirt-kvm-f62/veeam-rhv-12-1-command-removeimageticketvds-failed-t91699.html#p510618

so I made some investigations and recognized, it seems to be an Issue with 
Snapshot

1. I created a Snapshot

https://paste.fo/c0b8e77a3400

what works

2. Then I tried to deleted the snapshot, what didn't work

https://paste.fo/013e5632e0d6

So I logged in to a node and checked several things

First strange thing was, I can see pvs vgs etc, I am used, that ovirt hides 
them in the System (on one of those nodes it's still the case) but anyways

[root@ovnb05 ~]# pvs

So I did

I have never seen an unknown before, so I guess something happened to that LUN

But the LUN is available and in /var/log/messages I can't find any issue with 
the LUN or the path etc.

[root@ovnb05 data-center]# blkid  |grep uHJs0a-T7R3-2H8E-15W9-cGqW-ZN1e-xsdCsb

So I did some nasty stuff, like removing it and trying to add it again, through 
that process it told me that there is no meta Data on the Device

So at the End I am a little bit lost now.

Maybe the storage was failing for some reason or maybe veeam messed something 
up, but what leaves me afraid is, that the Ovirt-Engine didn't show me any 
Problem with the Cluster or the Storage.

I mean it's obvious, that there was/is a huge failure with the storage and 
Ovirt did not recognize neither did it alarm me.

At the moment I detached the LUN from the Storage Domain and created a seperate 
one (cause I recognized that having several LUN's in a Storage Domain seems to 
be an bad Idea)  and one PVS is now hidden, the other one not

[ovirt-users] Snapshots and quotas

[Mitja Mihelič]

Hi!

We are using oVirt 4.1.9 with quotas enabled. The usual quota is 40GB 
per user, usually used for a webserver. It is created from a template 
with a 40GB disk.
When such users try to create a snapshot of their VM, oVirt blocks the 
operation with "Cannot create Snapshot. Quota has insufficient storage 
resources."


I could increase the quota to 2x size. But then users would create 
additional disks, snapshot creation would fail due to insufficient 
storage resources and we're back to square one.


I could increase "Storage Grace" to 200%. It would take users longer to 
figure out that they can create additional disk even if the quota showed 
100% full. But sooner or later we would be back to square one.


Is it possible to exclude snapshots from the quota system?

Kind regards,
Mitja

P.S.
"Storage Threshold" is currently set to 80% and "Storage Grace" to 120%. 
Where can we change the default settings to something else?
E.g. new quotas would have "Storage Threshold" set to 90% and "Storage 
Grace" to 160%.

[ovirt-users] Snapshots - Preview button greyed out

[Leo David]

Hi Everyone,
I am encountering an issue on my oVirt 4.2 self-hosted engine installation.
Suddenly the "Preview" button in snapshots menu became inactive,  I just
cannot revert any previews snapshots.
This feature worked fine over the last month, but now it seems to be just
inactive.
Any thoughts on this ?

Thank you very much !

Leo

[ovirt-users] Snapshots don't seem to work with Windows VMs

[jmp242]

I've been testing with Windows 10 1607 LTSB and created several snapshots. I 
can preview each one, but they all boot with the same configuration and 
software installed and files as the "active VM" - so I cannot see at all how to 
roll back changes. Is this a known issue? I believe I'm following the 
documentation properly, but I can't see that the snapshots are doing anything.

I'm testing on Scientific Linux 7.4 using oVirt 4.2.2.6-1.el7.centos.

[ovirt-users] Snapshots from User Portal in ovirt 4.2?

[Brian Chow]

After upgrading from 4.1 to 4.2, we can no longer find the snapshot
functionality in the User Portal -- the documentation is still referencing
the 4.1 UI.  Was this removed from the user portal?  Moved to a different
area?  Are the required permissions different from 4.1?

commit iirc is post 'preview', which would revet to them.
you can just delete.
yes, only cold delete supported in 3.4.
3.5 brings live merge, but will require a supporting libvirt/qemu-kvm 
version providing that feature (still in development)

Thanks a lot for the tip and the quick response.
Indeed it was a browser issue (Firefox 26 on Fedora 20) - Refreshing the

Subject: [Users] Snapshots not visible in webadmin

Hi,

I created a snapshot of a virtual machine in my oVirt 3.4 environment
which worked fine, but in the Snapshots tab the snapshot isn't visible -
in Custom Preview Snapshot window I can see the snapshot (see attached
screenshot).

Do you have any idea why I can't see my snapshot or is this a already
known bug in 3.4 pre-release?

 Subject: [Users] Snapshots not visible in webadmin
 
 Hi,
 
 I created a snapshot of a virtual machine in my oVirt 3.4 environment which
 worked fine, but in the Snapshots tab the snapshot isn't visible - in Custom
 Preview Snapshot window I can see the snapshot (see attached screenshot).
 
 Do you have any idea why I can't see my snapshot or is this a already known
 bug in 3.4 pre-release?

 Betreff: [Users] Snapshots not listed for VM using 3.3.4

 I have two VMs in my cluster, one is CentOS 6.5 and one is CentOS
 5.10.  I have updated qemu on the ovirt nodes to use the RPMs from
 http://jenkins.ovirt.org/view/Packaging/job/qemu-kvm-rhev_create_rpms_el6.

 # yum list installed | grep qemu
 gpxe-roms-qemu.noarch 0.9.7-6.10.el6@base
 qemu-img.x86_64   2:0.12.1.2-2.415.el6_5.4
 qemu-kvm.x86_64   2:0.12.1.2-2.415.el6_5.4
 qemu-kvm-tools.x86_64 2:0.12.1.2-2.415.el6_5.4

 I am able to perform a snapshot using the web UI, which succeeds, but
 the snapshot is never listed in the Snapshots tab for either VM.

 Maybe be only a temporary problem and a browser restart could help
 see https://bugzilla.redhat.com/show_bug.cgi?id=1058618


Opening in a new browser did the trick.  Thanks!

 Running virsh -r snapshot-list domain for either VMs shows no snapshots.

 Attached is vdsm.log and engine.log (output when creating snapshot of
 EL6 VM) and vdsm2.log and engine2.log (output when creating snapshot
 of EL5 VM).

 Engine and nodes are updated to 3.3.4

 If this is just Web UI issue than it is known for long time. But there's
 no clear reproducer (BZ was filled for RHEVM 3.3). This has something
 to do with Firefox cache. With clear FF profile snapshots are visible.
 But after some time when are not visible until full reload of the page.

At least one scenario to reproduce the bug was filed in this BZ 1058618

Hi Jiri,

You are right, chrome shows the snapshots. I'll change the bz to reflect
this, you may mark it as a duplicate then.

if you are asking on qemu behavior then yes.
ovirt doesn't support this type of snapshot (with state) tet, and is 
using qcow2 with external backing file (which allows to use a raw image 
for the base one).

there is active work to add snapshot with ram.



* snapshots is only for block devices, are done offline


why not nfs/posix/localfs?



* live snapshot is only for block devices, can be done online


non block as well.



* snapshot tree with branches is not supported now

   am I right?


apart from a special state of previewing an older snapshot, no.



So my understanding there is no way to have a photo, in qemu language
_checkpoint_, in VMWare language _snapshot_ without interupting the VM.
Am I right? Any comments?


live snapshot with ram should cover this. interruption to vm is supposed 
to be similar to live migration - not noticeable (YMMV).
