5 dead hard drives in a span of 2 months - what should I be checking?

  • 772

So we got a nice new HP DL380 server with a fancy RAID card about one year ago.

2 months ago a hard drive failed. Thank goodness for RAID5... except that the RAID card only sort of worked and the machine hard reset. After fvck it came back up.

6 weeks ago another drive fails. Machine hard reset again, came back up.

4 weeks ago another drive fails. Machine hard resets. The data center puts a new drive in, and the new drive fails. Replace that drive. After a fvck it comes back up.

This morning, yet another drive (this is the 5th drive now, for those who are counting) reports "SMART imminent failure".

Needless to say, we've moved everything off this server so that it's not in use anymore.

Can anyone think of anything that could be going on to cause this sort of scenario? I find it hard to believe that there could be this many bad hard drives. Is the RAID card toasting hard drives? Power supply issue?

    1. Controller failure
    2. bad controller firmware
    3. faulty drives supplied by the hoster (some of the less reputable ones tend to do that)
    4. bad combo of disk and controller firmware
