Subject: Questions on RAID alignment
Date: Thu, 20 Sep 2012 13:11:38 +0200 [thread overview]
Message-ID: <505AF9EA.7030603@shiftmail.org> (raw)
Hello list
a few questions
1- Does XFS support alignment to concatenation RAIDs (e.g. linear over
raid1) similarly to striped ones? I am guessing probably su and sw
should not be specified and the agcount should be multiple of the number
of the concatenated devices, is that correct?
2- Can mkfs parameters be altered after creation, e.g. after growing a
RAID and then growing the XFS fs, can I also alter su, sw, agcount somehow?
3- I seem to remember there was an xattr that one could attach to /home
(if /home was under XFS) so that every user (subdir of /home) would get
a different AG in a different RAID device. I cannot find that
information anymore on the internet; could you refresh my mind?
Thank you
Spelic
