My newly upgraded opensolaris 2008.11 laptop crashed last weekend. (The OS was installed from the os 2008.11 live-cd and then upgraded using the package manager to snv_111.) I was trying to copy a large virtual pc image from my wife's imac to the laptop. On a whim I had decided to create a separ

Hi Grant, We have predefined ACL sets, which integrated into build 99. With ZFS delegated permissions, you can create a permission set that can be re-used. See the example 9-2 here: http://docs.sun.com/app/docs/doc/817-2271/gbchv?l=en&q=permission+sets&a=view zfs allow [-s] ... perm|@setname

Hi all, Is there a simple way to grant blanket conditions to zpools? I know about the individual commands, but I want to give our DBAs the permissions to snapshot, clone, promote, rollback, rename, mount, etc. anything within their zpools. I'm kind of new to delegations. Thanks. ___

There was a prior discussion about doing HA-NFS by using zfs send/recv to replicate the failover system's independent storage, and the conclusion was that it wasn't doable because NFS needs identical fsids on both systems. But zfs send/recv generates a different fsid on the failover, and that r
