Subject: convert legacy array in place?
Date: Sun, 14 Aug 2005 14:40:12 -0700	[thread overview]
Message-ID: <42FFBA3C.1010102@csun.edu> (raw)

Hi,

It seems like this should be a FAQ but careful google and mailing list 
archive searches didn't seem to turn up anything.

I have two machines with legacy RAID-0 arrays created with raidtools.  I 
have updated one to Fedora Core 4 and now use mdadm.  Am I correct in 
thinking I have to use "mdadm --build" every boot to access the array?  
My mdadm.conf contains

DEVICES /dev/hda1 /dev/hdb1 /dev/hdc1
ARRAY /dev/md0 level=raid0 num-devices=3 
devices=/dev/hda1,/dev/hdb1,/dev/hdc1

but the array doesn't seem to come up by itself on boot.

On the same lines, can this array be converted to a new style array just 
by writing new superblocks, or do I have to do the 
backup-reformat-restore thing?

TIA.
