FC4 RAID1 DegradedArray event

[George Pappas]

Hi all,

I have been experiencing some problems with my RAID1 configuration.  I 
am using two 160GB Seagate drives that have been configured identically ie

/dev/sda1   *           1          51      409626   fd  Linux raid 
autodetect

/dev/sba has the same partions.

/proc/mdstat reveals that the Raid Array has lost the sda drive, this 
had occured earlier but only dropped part of the sda drive not all.  I 
was able to add the drive back by using mdadm... but 2 days later this 
has happened again.  Has anyone else had this problem? or is able to 
guide to further diagnosing my situation.
