Re: [zfs-discuss] Adding slices from same drive to a pool

Are there any known issues with concatenating slices from the same drive? Having done this in the past (many builds ago) I found the performance wasn't good. It is really bad if you tried to mirror between different slices of the same drive (use copies=2 instead). If the old swap and root slices are after the ZFS root pool then you should be able to use format to delete them and add them onto the end of the slice the pool is in. If they are before it then I think you are out of luck. If they are before the ZFS root pool one possible thing you might be able to do would be to boot failsafe (which runs compeltely from RAM) then making sure the pool as NOT imported use some dd to shift the stuff (overlaping slices might help with this). But I'd make sure you have a full and verified backup before trying that. Note that I've not tried this myself but I might be tempted to give it a go on my OpenSolaris 2008.05 (upgrade to snv_93) system since it has swap as a separate slice at the start of the disk. -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Adding slices from same drive to a pool
I'd like to extend my ZFS root pool by adding the old swap and root slice left over from the previous LU BE. Are there any known issues with concatenating slices from the same drive?
