unable to open chunk store. no such file or directory. Also missing vm disk

[surfing_IT]

Hello,
I'm running PVE 6.2-12 and PBS 0.9-0. I get this message after a reboot in the PBS gui:

# Bad Request (400)
# unable to open chunk store 'Magi_Backups' at "/dozer/backups/.chunks" - No such file or directory (os error 2)

My cluster is named Magi, and my one and only VM on this server cannot start. Error is:

# TASK ERROR: volume 'vm:106/vm-106-disk-1.qcow2' does not exist

I'v also recently had errors with one of my vm's not backing up, with the error:
# VM 100 qmp command 'query-backup' failed - got timeout
All other vm's backup just fine.

I'm fairly new to proxmox admin, but could it be that my ZFS raidz2 failed or borked?

possible it is not mounted correctly? check with zfs list -o name,mountpoint,mounted

 

[surfing_IT]

root@melchior:~# zfs list -o name,mountpoint,mounted
NAME           MOUNTPOINT      MOUNTED
dozer          /dozer               no
dozer/backups  /dozer/backups       no
dozer/iso      /dozer/iso           no
dozer/vms      /dozer/vms           no

That's not good, how to mount them? I restarted the host and nothing

 

[fabian]

zfs mount -a

that should happen aumatically on boot unless there is some issue with importing the pool - please check the boot log for various ZFS services/targets.

 

[surfing_IT]

zfs mount -a gives the error:
cannot mount '/dozer': directory is not empty

however,
zfs mount dozer/backup
this^ mounted the directory

I could not find anything in the boot log to find out why this occurred. There are far too many 404 bad request entries as the host looks for and failed to find the missing directory.

Thanks for your help, I'm still worried about why this happened.
Mark as solved

Same happened to me shortly after the installation and I also never found out why it happened ...
But it's been the only time so far. After a remount there were no further issues.

 

[surfing_IT]

restarted and it happened again. and i still can't load my vms

I have the same Problem. If I shutdown the server (not only reboot), the Pool comes online again with the next boot.
