Subject: Data Offset
Date: Thu, 10 May 2012 19:42:10 +0200 [thread overview]
Message-ID: <20120510174210.GA2991@lazy.lzy> (raw)
Hi,
after the RAID-5 problem, I just realized that
other RAIDs I have, including a multi RAID-6,
have different data offset for each component.
This seems to be quite of a problem, in case
"Create" is used to recover an array.
Obviouly, if a 4 disks RAID-5 has 2 disks with
one offset and 2 with another, it will not be
possible to re-create it (saving the data).
Is there any way to fix/prevent such issue?
Shouldn't "mdadm" make sure all offset are
the same? Or try, at least...
What I noticed is that, adding a disk later,
might cause different offsets.
Any idea?
Thanks,
bye,
