Re: mdadm Issue

Hi,

I obtained this email address from Neil Brown's blog site as being the
address to email if we had any issues with mdadm or Linux software RAID in
general.

I have an issue with some RAID1 arrays I have set up on an Ubuntu (Gutsy
7.10, 2.6.22-14-server) installation where arrays seem to randomly become
degraded during the boot process.  I have included some of the superblock
data captured before a shutdown, and after boot.  Note that arrays 5-8 are
degraded after boot.  It also happens with arrays 1-3 so it's not an
extended partition issue.  Notice that the Events field for the arrays that
are degraded have a different value for both of the mirrors and even the
array itself.

Any suggestions you could offer would be greatly appreciated.  I would
prefer to resolve this problem before deploying the server in a production
environment.

Regards,
