Subject: RAID-10 explicitly defined drive pairs?
Date: Mon, 12 Dec 2011 12:54:59 +0100 [thread overview]
Message-ID: <20111212115459.GC20730@fi.muni.cz> (raw)
Hello, Linux RAID gurus,
I have a new server with two identical external disk shelves (22 drives each),
which will be connected to the server with a pair of SAS cables.
I want to use RAID-10 on these disks, but I want it to be configured
so that the data will always be mirrored between the shelves.
I.e. I want to be able to overcome complete failure of a single shelf.
Is there any way how to tell mdadm explicitly how to set up
the pairs of mirrored drives inside a RAID-10 volume?
Thanks,
-Yenya
