Restore LXC from PBS fails: Use 'none' to disable quota/refquota

[mattjn]

Hello all,


I intend to restore a ct backup from pbs, however restororing fails with

recovering backed-up configuration from 'pbs01:backup/ct/100/2021-03-05T00:00:01Z' Using encryption key from file descriptor Encryption key fingerprint: TASK ERROR: unable to restore CT 105 - zfs error: cannot create 'storage/subvol-105-disk-1': use 'none' to disable quota/refquota

There is no quota assigned at all:

zfs get all storage |grep quota storage quota none default storage refquota none default


The backup is ~407gb and encrypted.


Any hint how to distable quota?

Thanks and regards,

Matthias

Hi all,

can some pls assist me in this issue? Maybe I missed to provide you with the full picture:

There are two zpools:

mattjn@pve:~$ sudo zpool list
NAME      SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
rpool     356G   254G   102G        -         -    40%    71%  1.00x    ONLINE  -
storage  2.72T   555G  2.18T        -         -     1%    19%  1.00x    ONLINE  -

mattjn@pve:/etc/pve/lxc$ sudo zfs list | grep -i subvol-100-disk-0
rpool/data/subvol-100-disk-0                                      20.0G  30.0G     20.0G  /rpool/data/subvol-100-disk-0
storage/subvol-100-disk-0                                          395G  1.99T      394G  /storage/subvol-100-disk-0

The LXC container:

arch: amd64
cores: 1
hostname: fileserver
memory: 4096
mp0: local-storage:subvol-100-disk-0,mp=/media/storage,acl=1,backup=1,size=0T
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=4E:4B:55:62:F3:33,ip=dhcp,ip6=dhcp,type=veth
net1: name=enp1s0,bridge=vmbr0,firewall=1,hwaddr=F6:91:D7:36:37:E5,ip=dhcp,ip6=dhcp,type=veth
onboot: 1
ostype: debian
parent: SystemRunningStable
rootfs: local-zfs:subvol-100-disk-0,size=50G
swap: 4096
unprivileged: 1

As backup is set to True, the mountpoint is included in the backup, hence the backup sums up to ~407gb. On the remote proxmox backup server there are 6 backups in total, the validation checks are passed successfully. For all of these the error given above is shown when restoring them.

I really appreciate your efforts pointing me to the right direction troublshooting this!

Regards,
Matthias

please file a bug at https://bugzilla.proxmox.com - there seems to be a special case missing for "unsized" disks (e.g., ZFS volumes with no quota)

Hi Fabian,

thanks for pointing me in the right direction. I created #3345.

Thanks a ton!

We have the same problem with moving the datastore.
how can we fix it?


TASK ERROR: zfs error: cannot create 'zfs/subvol-122-disk-0': use 'none' to disable quota/refquota

 

[fabian]

the issue in this thread is fixed: https://git.proxmox.com/?p=pve-storage.git;a=commit;h=8c858f7eebd6e130d06222286645a8f7c495f17c

so either upgrade (to libpve-storage-perl >= 6.3-9) or describe the issue you have with more detail

thanks
Ok we set refquota and quota for the original datastore, then it was possibel re move the volume.
