Ace, glad my post was of use Paul. It’s a slightly annoying bug actually, one I wish Sun [Oracle] would address!

We had similar situation. Root’s umask was set to 027 so that when ZFS auto-created mount dirs, they were set 750. Exported, fixed the perms, re-imported and now we’re good. Thanks for the tip!

…and set root’s umask to 022

Here is your answer!!!
If you are mounting a zpool, say for instance TANK… and you have its mountpoint set to /app
you have a bunch of zfs partitions created on top of it and you are having this user recursive removal issue (i.e. user cant use rm -rf /app/bob) do this.

zpool export -f TANK
chmod 755 /app
zpool import TANK

This Should Work!

Thanks Matt – that’s pretty much the way I was dealing with it before I found the root cause though. Nice to have a workaround, nicer to know what’s causing the issue I always think.

I hit the same issue with umask se to both 027 and 022. The following allows me to delete the files and directories.

rm -rf
find -depth -exec rmdir ‘[]‘ \;

rm -rf returns code 2 and rmdir returns code 0.

Deleting the directory as root works fine.

Sounds like it. However, that’s very old (build 36) and I would’ve thought a patch I’ve applied by now would’ve sorted the issue out. Maybe not though.

This looks to be spot on :

*oops, I hit enter too soon*
If you become the user and do ‘ls -la’ of the ZFS mountpoint you also get a “Permission denied” error.

Yes the aclinherit was a red herring, sorry.
If you become the user and try to ‘ls -l’ the zfs mountpoint
