It should be pretty simple to do. We have acl_get()/acl_set() which are public interfaces. The acl_set() function will attempt to translate the ACL when necessary prior to setting it. Translation from POSIX->ZFS will always work. Here is an example from compress.c on how to retrieve/set an ACL with acl_get()/acl_set(). http://cvs.opensolaris.org/source/xref/on/usr/src/cmd/compress/compress.c#1658 Or take a look at how ufsrestore does it. It first has to build an acl_t structure and then sets the ACL via acl_set(). http://cvs.opensolaris.org/source/xref/on/usr/src/cmd/backup/restore/tape.c#1324 -Mark ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I haven't tried rsync. another data point is that ufsrestore doesn't work for ZFS ACLs yet either. grant. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] ZFS ACL support
Greetings, I've seen discussion that tar & cpio are "ZFS ACL aware"; And that Veritas NetBackup is not. GNU tar is not (at this time); Joerg's "star" probably will be Real Soon Now. Feel free to correct me if I'm wrong. What about other utilities like Samba and rsync? We'd like to share out ZFS storage via both NFS and CIFS, the latter of which is going to require Samba here. Is there a version of Samba which will allow SMB clients to do ACL's the way a Windows/NTFS file server can support? I've seen Samba do this (sorta) on a Linux Samba server using an XFS filesystem. Anybody tried this using Solaris/ZFS? In the rsync case, I can see using rsync to migrate data from old storage on UFS or SAM-QFS (which may have ACL's set), to new ZFS storage. It sure would be nice if rsync would copy the ACL's at the same time.
