Sorry, I did not intend this to be the solution to your problem. Just a much more stable method for creating the 1+0 array. With this method, losing 1 disk only requires re-syncing 1 disk. With the array as a 0+1, if you lose 1 disk, you lose the whole RAID0 array, which then requires re-syncing 2 disks of data. -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Brad Dameron Sent: Wednesday, January 26, 2005 3:33 PM To: linux-raid@xxxxxxxxxxxxxxx Subject: RE: Software RAID 0+1 with mdadm.

Still the same booting issue. Once it's booted I can run mdadm --assemble --scan and it will find just the stripe and then add it. I saw several people having this issue on a google search. But never any solutions.
