setfacl: operation not supported

viewcam · 11-29-2008, 11:48 PM

This has appeared on an earlier thread, but the answers don't seem to solve my problem.

setfacl -m u:dan:rwx /test/ghosts

gets the "operation not supported error."

apt-get and synaptic both report acl functionality is loaded.

Have added the acl switch in /etc/fstab, remounted, umount-ed and mount-ed several times.

fstab: LABEL=final /test ext3 user,defaults,error=remount-rw,acl 0 2

setfacl -t -m u:dan:rwx /test/ghosts

reports the correct result.

Any (other) ideas?

Thanks

Peter McDonald.

Just to make sure that ACL is activated on the file system, could you provide to output of this:

Code:

dumpe2fs <device> |grep -i "default mount options"

It this says ACL, I'm really not sure whats wrong.

mount the partition using acl
mount /dev/X -o acl dirname

I think he has already done this in fstab.

Thanks for the help. The dumpe2fs command and grep-ing for default mount options gave me the clue. It is showing none, but I umounted the device, and then mounted it with -o acl option; then, when I do a mount | grep acl, the device is now mounted with acl supported and allows the setfacl operation.

Thanks again. Much appreciated.

Peter.

Syed:

Thanks for your suggestion, I did exactly that, and it worked. The dumpe32fs set off a train of thought, so then I grepped the mount output for acl and showed none, I figured it hadn't mounted properly from fstab. Mounting directly, with -o acl was the answer.

Cheers,

Peter.

I was searching for help and found this post, which I know is a bit old, but I thought I would add my comment for future viewers.

I used the dumpe2fs command and did find that there were no specific mount options set against my filesystem. I added "acl" option to fstab and re-mounted. Dumpe2fs still showed no options set. I decided to check with the mount command and it now showed the acl flag as set:

Code:

dumpe2fs /dev/sda3|grep -i "default mount options"
dumpe2fs 1.41.12 (17-May-2010)
Default mount options:    (none)

mount|grep home
/dev/sda3 on /home type ext4 (rw,acl)

My setfacl command now worked fine
