ERROR: Backup of VM failed - command 'rsync --stats -h --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/314139/root//./ /mnt/pve/nfs-truenas/dump/vzdump-lxc-116-2022_09_01-18_17_35.tmp' failed: exit code 23

With stop mode backup done, but with suspend mode i have this error.
while using -v --progress in shell of the host i can't found error because of thousends of line, is there any option to have the log on a file?
Note: I disable ACL on the disq of my container.
 
Hello,

Please provide us with the output of pveversion -v and the container config pct config <VMID>.

Does another LXC have the same issue, or only 116 LXC?
 
Only this LXC all the reste are good, because it's the only LXC that have (features: fuse=1,mount=fuse,nesting=1) fuse activated.

Hello,

Thank you for the output!

Do any database work on this container, such as "MariaDB"? If yes, might to be like this issue [0]?

Can you also provide us with full output of the backup task log for the 116 container?

could you try running the same command directly after the backup has failed but add "--verbose" to the rsync parameters?
 
rsync --stats -h -X -A --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative --verbose '--exclude=/var/lib/php/sessions/' '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/5996/root//./ /mnt/proxmoxdb1/tmp-backup/vzdumptmp9116_105

?
 
Dear all,

I'm trying to do a backup of my LXC and get the following error message :

ERROR: Backup of VM 2000 failed - command 'rsync --stats -h -X -A --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/1086712/root//./ /var/tmp/vzdumptmp1496453_2000' failed: exit code 23
@DC-CA1 I used the command listed in your post

Code: 
rsync --stats -h -X -A --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative --verbose '--exclude=/var/lib/php/sessions/' '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/1086712/root//./ /var/tmp/vzdumptmp1458788_2000

but got the following response :

rsync: [generator] set_acl: sys_acl_set_file(var/log/journal, ACL_TYPE_ACCESS): Operation not supported (95) rsync: [generator] set_acl: sys_acl_set_file(var/log/journal/92a1899cf71b421195d2bace02687f72, ACL_TYPE_ACCESS): Operation not supported (95) rsync: [generator] set_acl: sys_acl_set_file(var/log/journal/92a1899cf71b421195d2bace02687f72/system.journal, ACL_TYPE_ACCESS): Operation not supported (95) rsync: [generator] set_acl: sys_acl_set_file(var/log/journal/92a1899cf71b421195d2bace02687f72/system@0006037b01295803-44461770961afd06.journal~, ACL_TYPE_ACCESS): Operation not supported (95)

Can you please advise how you got out of this ?

Please note that when I shutdown the LXC, the snapshot is done without any problems. Not sure why I can't i do when the LXC is up ?

@jensie I ran into the same error with some recently deployed PVE systems using ZFS. I found your post when googling the same.

Turned out this is a long known issue, I found this post which resulted in an update to the wiki.

Following the instructions in the wiki ended up resolving this for me.

Snapshot of LXC on ZFS​

If you can't create a snapshot of an LXC container on ZFS and you get following message:

Code: 
INFO: rsync: set_acl: sys_acl_set_file(archiv, ACL_TYPE_DEFAULT): Operation not supported (95)

you can run following commands

Code: 
zfs create -o mountpoint=/mnt/vztmp rpool/vztmp
zfs set acltype=posixacl rpool/vztmp

Now set /mnt/vztmp in your /etc/vzdump.conf for tmp

@glitchwitch this method worked also for me ! Thank you so much.
For future reference, the last step is effectively uncommenting and adjusting the following line
Code: 
tmpdir: /mnt/vztmp
in /etc/vzdump.conf
