When I tested with ZFS, snapshot directory could not access from NFSv3 client. >How-To-Repeat: 1. create zfs volume % zpool create -m /devel zdevel2 da0 % zfs create zdevel2/nfs-test 2. NFS export zfs volume/mount NFS % zfs share -a % zfs set sharenfs="-alldirs -maproot=0:0 -network 192.168.1.0 -mask 255.255.255.0" zdevel2/nfs-test 3. NFS mount % mount -t nfs nfs_server:/devel/nfs-test /mnt2 4. create new snapshot zfs snapshot zdevel2/nfs-test@today 5. access from NFS server to snapshot directory I could access snapshot directory, and correct 6. access from NFS client % cd /mnt2/.zfs % ls snapshot/ OK % cd snapshot/ % pwd /mnt2/.zfs/snapshot OK % ls -la total 2 dr-xr-xr-x 2 root wheel 2 Nov 9 23:03 ./ dr-xr-xr-x 3 root wheel 3 Nov 9 23:03 ../ drwxr-xr-x 3 root wheel 3 Nov 9 23:04 today/ % cd today/ % pwd /mnt2 NG!! and files in /mnt2/.zfs/snapshot/today/ is same as current file, not same as snapshot revision(in NFS server) >Fix: OpenSolaris was already fixed from below mail, after March 2006 http://mail.opensolaris.org/pipermail/nfs-discuss/2006-March/001224.html Import new/latest zfs source into FreeBSD? >Release-Note: >Audit-Trail: >Unformatted:
