RAID not mounting all of a sudden.

Posted by Keith Roberts on March 18, 2009 at 10:30 pm

I have been working on a DV project with media on a Burly enclosure with 5 – 1.5TB Seagate Barracuda drives in them. 4 of the drives are a RAID-0. And the 5th drive is just a work drive. Things were working fine for several days. Then Final Cut crashed a few times, so I decided to trash prefs and repair permissions. When I restarted, the RAID would not mount, but the work drive did. If I go into disk utility, I can see the 4 slices of the raid. But if I click on any one of them both ‘verify disk’ and ‘repair disk’ are greyed out – along with ‘mount’. If I try to eject the slices, I get an error. I tried moving the drives around in the enclosure, but I get the same thing – work drive mounts, raid does not.

Any suggestions on troubleshooting techniques? Could it be that one of the drives failed so the whole raid is shot? I have a copy of all the media at another location that I can copy back over and relink, but I’m afraid to raid again. I’ve used these enclosures and drives non-raided without any problems for months.

Any thoughts would be appreciated.

Thanks,
Keith

You absolutely positively need to run DiskWarrior on the raid, and if you don’t have it already, run and get it. If your raid can be fixed DW can do it.

None of the disks in the burly enclosure show up in Disk Warrior.

Any other thoughts.

[keith roberts] “None of the disks in the burly enclosure show up in Disk Warrior. “

That’s not good Keith.

Shut everything down and let it all cool off for a while — like for an hour or more. Now, reseat your SATA controller card. Then, remove all non-essential peripherals, such as firewire drives. Then, try to fire it up again and see if you can see your drives in Disk Warrior. Sometimes this will work, sometimes not. If once of your drives is french fried you may have a problem and you have to then test them one by one to see which has gone south. Thankfully, as you’ve said, you have a backup.

Thanks for all the help, David. I’m on the fence as to whether to just cut my losses and go make a copy of the media from the back up. If I can get this enclosure over to the office by 7:00, I can have my assistant let the copy run over night, so I wouldn’t lose any time tomorrow.

I’ll let you know if I fix the problem though.

Thanks again,
Keith

Better at least try reseating the controller card. That can work miracles, and if that doesn’t fix the problem you might be in for worse to come.
