[SOLVED] rsync: set_acl: sys_acl_set_file(archiv, ACL_TYPE_DEFAULT): Operation not supported (95)

If I want to make a backup from my LXC container on local storage I got this error message:

It seems that your /tmp mount doesn't accept posix acl. Is it just part of your root mount, or did you set a tmpfs on that?

 

[fips]

its the default folder from root.
I just set the vzdump.conf to use /tmp, but even when I comment it out, it produces the same error messages...

 

[windinternet]

Then it seems that your root is mounted with noacl. Or are you using a different file system like ZFS on the root?

 

[fireon]

Say:

mount | grep tmp
mount | grep acl
cat /etc/fstab

 

[fips]

mount | grep tmp:

udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=2049440,mode=755)
tmpfs on /run type tmpfs (rw,nosuid,relatime,size=3284760k,mode=755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)
tmpfs on /sys/fs/cgroup type tmpfs (rw,mode=755)
tmpfs on /run/lxcfs/controllers type tmpfs (rw,relatime,size=100k,mode=700)
cgmfs on /run/cgmanager/fs type tmpfs (rw,relatime,size=100k,mode=755)

mount | grep acl:
rpool/ROOT/pve-1 on / type zfs (rw,relatime,xattr,noacl)
rpool on /rpool type zfs (rw,noatime,xattr,noacl)
rpool/ROOT on /rpool/ROOT type zfs (rw,noatime,xattr,noacl)

cat /etc/fstab:
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/zvol/rpool/swap none swap sw 0 0
proc /proc proc defaults 0 0


OK, as we can see my root set to noacl...
Well I just went through normal setup...

How to change it?

 

[windinternet]

The best thing to do is to create a new mountpoint for it in the zfs pool and set that to acl. Otherwise you may run into a host of trouble with new LXC containers.

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.

One more thing. If you are running on ZFS, turn off SWAP or try the settings in this post:

Great, workes like a charm!!
The Proxmox guys should include that to their zfs troubleshooting wiki.

The wiki is open for everyone, so you are invited to improve the docs.

Thank goodness I came across this post. I just tried the solution above and it works beautifully.
With that said, it seems like this is only the issue for me if I have Proxmox installed on zfs volumes (I don't have this issue on the ext4 volume from one of my other nodes in my cluster).

BTW, for those new comers like me, here is what I did to set /mnt/vztmp in /etc/vzdump.conf for tmp:

# nano /etc/vzdump.conf

# vzdump default settings

#tmpdir: DIR    <-  This is the original code in the file.  I always like to keep a copy just in case I need to rollback in the future
tmpdir:/mnt/vztmp

In addition forgot to add that if you are using zfs, you'll need to run the following lines to make it effective.

zfs create -o mountpoint=/mnt/vztmp <pool>/vztmp

for example:
zfs create -o mountpoint=/mnt/vztmp rpool/vztmp

After that you should be good to go.
