[ovirt-users] Cannot delete snapshot

[Giulio Casella]

Hi,
I'm having (another) issue working with snapshots.

Since a few days my backup system (storware vprotect) cannot delete a
snapshot. Message reported by SPM is:

HSMGetAllTasksStatusesVDS failed: value=Volume does not exist:
('6180c2e8-141a-4126-bcb1-5af5caa98175',) abortedcode=201

Other snapshots from other VMs are working fine (created and deleted as
needed).

I verified it, I can reach on SPM filesystem other snapshots from the
same VM, but that one doesn't exist.

I suspect that during normal backup management that snapshot has been
correctly removed from file system, but still live in ovirt database.

I'm pretty sure vProtect use ovirt API to operate, it doesn't directly
interact with ovirt database. That's why I'm talking to you and not to
storware guys.

Is there a (safe) way to get rid of that snapshot?

TIA

Regards,
Giulio Casella

Re: [ovirt-users] Cannot delete snapshot or export VM after adding disk

I hope not. Now I realized that this is a serious problem on other VM's
where it isn't possible anymore to delete snapshots, create snapshots.
These affects 3 very important VM's which costs a lot of work-hours :-(

Smells like a bug.

Please file a bug and attach full vdsm and engine logs.

[ovirt-users] Cannot delete snapshot or export VM after adding disk

[gregor]

Hi,

after the following workflow I can't remove or create a snapshot neither
export the VM.

- Create a VM
- Add a disk with 1GB
- Make a snapshot
- Add another disk with 1GB
- Export the VM

Now you I get the following error in the events list:

VDSM host01 command failed: Error during destination image manipulation


Did I understand something wrong or is there a bug?

Besides: The web-interface is extremely slow and copy&paste the error
messages are painful.
