Hi,
Im running FreeBSD 8.0-RELEASE
(FreeBSD hostname 8.0-RELEASE FreeBSD 8.0-RELEASE #1: Tue Dec 1 =
16:10:08 CET 2009
peter@hostname:/usr/obj/usr/src/sys/GENERIC amd64)
and have a MTP-raidcard with a configured mirror.=20
mpt0 Adapter:
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.
and=20
delete volume
Delete the volume volume. Member drives will become =
standalone
drives.
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?
