Hi Gary,

We also had a high disc failure when we added 30 mirrored drives to
our system, we lost four the first night and another 6 disabled
during the next week. Turns out there is a bug in the mirroring
software that lets one side of a mirrored pair time out. We put on
patch mpe somethingorother and things seem to be fine now.
