Hello, All:

I'm configuring a SuperMicro 5013CM8 (with on-board Adaptec AIC-7902B U320 SCSI controller controlling two Seagate ST373207LC 73GB U320 hard-drives) and am experiencing random crashes: The system ocassionally blurts out a bunch of stuff about the SCSI system and then freezes.

md3 : active raid1 sdb6[1] sda6[0]
      1052160 blocks [2/2] [UU]
        resync=DELAYED
md4 : active raid1 sdb7[1] sda7[0]
      50660864 blocks [2/2] [UU]
[======>..............] resync = 30.4% (15410224/50660864) finish=56.9min speed=10315K/sec

What does this mean? How can I fix it?


That in itself is not a problem.
The raid subsystem is not going to resync more than one array at a time here, or else your drive heads would thrash themselves silly. It will progress its way up the list as each resync completes.

A dead restart on my old server used to do exactly the same thing.
As for your SCSI problems, I'm afraid I can't help.

Regards,
Brad
