That said, if the space on the disk (for the 2 partitions) is contiguous (which it doesn't appear is true in your case,) or could be made contiguous by moving some other slice out of the way, then one way you should (note: I haven't tried this, and there is chance for human error to mess things up even if it will work - and there's some chance it won't work even if you do it perfect,) be able to grow the root pool by deleting the new (second) partition, and redefine the original partition to extand across the space of both partitions. Once that's done, a zpool replace c1t0d0sX c1t0d0sX should notify ZFS that the slice is bigger, and it will grow the pool to match. You have s4 and s0, so I bet the space is not contiguous, and I'd guess the free space is earlier on the disk, not later. You might be able to get around that by mirroring s4 to s0 first then detaching s4, so that you're only using s0 and the beginning of the disk... but that's just more changes that could introduce problems. Needless to say, I wouldn't try this on a system I really needed with out: 1) Really good backups! and possibly, 2) Trying it out first on a virtual machine, or different HW. Personally, unless I really wanted to prove I could do it, I'd just backup and reinstall. ;) sorry. -Kyle > -Wyllys > > > This message posted from opensolaris.org > _______________________________________________ > 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
