[urgent] supermicro ejecting disks

[urgent] supermicro ejecting disks

[Louis-David Mitterrand]

Hello,

We recently changed our main server to a Supermicro with 6 scsi disks in 
soft raid6 with kernel 2.6.18. 

After running OK for a few days, 3 disks were suddenly ejected from the 
raid6. We are now trying to reassemble the partition in another box but 
keep getting a "superblock corrupted" error on the fs. We're in a pretty 
bad state right now, as this is a production machine. Of course we have 
bakcups but restoring them will take some time.

Does anyone have any idea of what has happended and how to fix it?

Thanks,

I forgot to add that to help us solve this we are ready to hire a paid 
consultant please contact me by mail or phone at +33.1.46.47.21.30

Thanks

Update: we eventually succeded in reassembling the partition, with two 
missing disks.

Your update would be far more interesting if you found out why it 
ejected three drives at once... The obvious common failures, controller 
and power supply would not prevent reassembly in a functional environment.

Actually the motherboard and/or its on-board scsi controller turned out 
defective. Reassembly succeded once the disk were transfered to another 
box.

Has anyone seen such hardware failure on a brand new SuperMicro machine?

Thanks,
