Subject: Is shrinking raid5 possible?
Date: Mon, 19 Jun 2006 12:30:29 +1000	[thread overview]
Message-ID: <44960C45.9050407@anu.edu.au> (raw)

Hi,

I'd like to shrink the size of a RAID5 array - is this
possible? My first attempt shrinking 1.4Tb to 600Gb,

mdadm --grow /dev/md5 --size=629145600

gives

mdadm: Cannot set device size/shape for /dev/md5: No space left on device

which is true but not particularly relevant :). If mdadm
doesn't support this for online arrays, can I do it offline
somehow?

I'd like to retain the ext3 filesystem on this device,
which I have already shrunk to 400Gb with resize2fs.

Thanks for any help,
Paul
