Backup hangs at 99%

[muekno]

Hello Fiona,

tries a new restore of 507 just some minutes before. Looking at the free space of V_Space the 507 used space was released and I hope if restore is complete in some hour the vm will start up fine.

Do you have any idea why I had disk 0,1,2 of the 507 after the restore tonight. Three times 600 gb is too much for 1TB, even with compression and deduplication. 0, 1, are marked as unused under hardware, so I deleted them and had space to start the rest. My nerves are blank

Kind regards
Rainer

I can't tell from here, that would require seeing the whole task history logs. One possibility would be that you changed where the drive is attached (e.g. from scsi0 to scsi1) and then restored a backup. Then the original disk is kept, as it's not considered to be "the same" as in the backup. Another is failed migration attempts where cleanup of the migrated disk doesn't work in some edge cases.

Hello Fiona,

whats urgent for me is to get my system complete up and running. My 500gb VM is restored and seams OK,
My internal mail system seam OK too.

But my mail gateway the 505 VM seams to have problems since the disk full. That was the VM starting the problem with backup. Perhaps the existing snapshot, now I did a rollback to that snapshot. The cluster log on the bottom says OK, but I wonder the snapshot screen still shows the snapshot and the you are here.

From my test I know the snapshot was gone. This VM is also my internal DNS

Regards
Rainer

P.S: if there is a backup or restore running then reaction of the VMs are quit slow, while the summary of the PVE Server shows a CPU load of 25% +/- and 15GB free RAM, LAN is 1 GigaBit

A snapshot is not automatically removed after you roll back to it. Like that you can roll back again, should you need to. Since the current state is immediately slightly different from the snapshot, there always will be a separate You are here.

Hello Fiona,


as I remember from my tests some weeks ago the snapshots are gone, but is good as it is.
As far as I testet everything is running fine again, still som certificates isues, but I'l figure that out.

Even we haven't found the reason for the stuck backup (did you check if it my be as there was a snapshot active) I will declare this post as SOLVED.

Thank you once more for your help and patience. I learned a lot and that is good so

Best Regards
Rainer

Hello Fiona,

sorry to reopen that thread. In the Meantime I updated the 505 VM from Debian 11 to 12 , beside others, without any problem, everything is running fine, no I tried to backup all my VMs after the upgrade. The first three could be backuped (suspend mode) with out any problem.
The 505 VM dis stuck at 99 % again. Fortunately the VM is still runing and working. Next I stop the backup successfull. Now I wanted delete the faulty backup, was not possible

Thats my mail gateway, so thats critical

what to do unlock that VM

P.S.

after qm unlock and finaly qm stop I got the VM down. Starting it again let it run fine.

Must I live with never be able to backup that VM

ERROR: interrupted by signal
INFO: aborting backup job

Check for running was via a SSH connection
Now after triying to connect via console I can not access the VM any more

VM 505 qmp command 'set_password' failed - unable to connect to VM 505 qmp socket - timeout after 51 retries
TASK ERROR: Failed to run vncproxy.

No ssh connection possible
VM shows a disk sign

Thats my mail gateway, so thats critical

what to do unlock that VM

Regards

Rainer

P.S.

after qm unlock and finaly qm stop I got the VM down. Starting it again let it run fine.

Must I live with never be able to backup that VM

Should it happen again, please try to obtain the debug trace with GDB while the VM/backup is stuck. If we are lucky, the cause of the issue can be seen there.
