Im running FreeBSD 8.0-RELEASE
(FreeBSD hostname 8.0-RELEASE FreeBSD 8.0-RELEASE #1: Tue Dec 1 16:10:08 CET 2009

and have a MTP-raidcard with a configured mirror.
Board Name: SAS3041E
Board Assembly: L3-01101-04F
Chip Name: C1064E
Chip Revision: UNUSED
RAID Levels: RAID0, RAID1, RAID1E
RAID0 Stripes: 64K
RAID1E Stripes: 64K
RAID0 Drives/Vol: 2-10
RAID1 Drives/Vol: 2
RAID1E Drives/Vol: 3-10
Now I want to split this mirror into standalone drives but I dont know if its possible. Since Im using
zfs anyway it seems better to let zfs take care of the mirroring giving it the possibility to self heal
and so on. and of course ease of administration.
When consulting the manual i see this:
clear Delete the entire configuration including all volumes and spares.
All drives will become standalone drives.
Delete the volume volume. Member drives will become standalone
IF! what this does is just leave da0 as one of the disks and makes the other disk in the mirror
available to the operating system as da1 then everything should be fine. But I cant take the risk
if everything goes boom. :D
Is there anyone that has any experience in this situation?
