If you use the latest developer release from genunix.org, it's already fixed. This is what I recommend, in general. http://genunix.org/dist/indiana/ It looks like the latest one is osol-dev-134 If you use the latest opensolaris release (2009.06) I'm not sure if it's already fixed. If you use Solaris 10, even fully updated, you are wise to ask this question. Because the fix is not present. If you don't already have the fix, the recommendation would be to partition the disks first. Throw away something like 1% of the disk intentionally. Yes this is extra work and a little wasteful, but it's preventive work for a real problem. http://docs.sun.com/app/docs/doc/806-4073/6jd67r9hu (Quoting Richard Elling) CR 6844090, zfs should be able to mirror to a smaller disk http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6844090 b117, June 2009 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
