Debian/kFreeBSD using ACLs on ZFS

Question

How can I use ACLs on a ZFS filesystem under Debian/kFreeBSD?

uname -a

GNU/kFreeBSD foo1 8.2-1-amd64 #0 Thu Oct 27 20:48:27 UTC 2011 x86_64 amd64 Intel(R) Xeon(R) CPU X3220 @ 2.40GHz GNU/kFreeBSD

I tried setfacl:

setfacl -m user:root:rwx /Storage/TestFile1

and it returns:

setfacl: /Storage/TestFile1: Function not implemented

I would like to use it as a fileserver, with samba.

Answer 1

ZFS on Debian/kFreeBSD is still experimental and I guess ACL's are not (yet?) working.

Anyway, ZFS on this OS means you run a file system ported from another platform (Solaris) and put in a kernel that is then working in an alien runtime environment (Debian) considered experimental. Doesn't sound like a good idea for a server.

Answer 2

I don't know about debian's userspace (which I presume uses the GNU utilities), but according to this guide it looks like ZFS ACL's are supposed to be set with chmod and read with ls -v:

chmod A+user:marks:delete:allow file.1

The info page for GNU chmod says that filesystem-specific attributes are normally set with a different command and suggests chflags or chattr, and ls -v is to "sort by version".
