Given that the dataset has 149G referenced, it could be all there. Does 'zfs list -rt snapshot sas/mail-cts' list any? If so, you can try using the most recent snapshot by looking in /sas/mail-cts/.zfs/snapshot/snapshot name and seeing if all your data are there. If it looks good, you can zfs rollback to that snapshot. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing

So far we have a pattern - in at least three cases the problem is related to mode value of the filesystem root directory Victor ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
