Subject: how to get 'peer disk' in raid configuration?
Date: Thu, 28 Jun 2012 03:51:05 +0400 [thread overview]
Message-ID: <4FEB9C69.9060608@gmail.com> (raw)
Few days ago met intersting question:
Let assume we have RAID10 on 4 disks. We want to remove two disks
without breaking array.
How we can know which drive is safe to eject? For 1st drive it obvious:
any of. Second is more complicated: we need eject mirror part of 'second
pair'.
How we can know exact topology of raid? (--detail does not provide
enough information, IMHO).
