I have a 550 with latest patches. I am having problems with mirroring, active monitor says:

Your system is configured for disk mirroring (RAID 1) using 2 disks.
The system is resynchronizing the information on the disks.

Then as soon as it is done resynchronizing, the server reboots, and the process restarts all over again.

This happened a few months ago, went on for about 14 hours, then it sync'ed up and everything was peachy 'till now.

Any ideas?
