Help! – Raid won’t mount

[Torrey Loomis]

Shawn,

Try shutting down both the RAID and the Mac.

Fire up the RAID, then fire up the Mac. See what happens.

BTW–what kind of RAID is it?

Thanks Torrey,

I’ve tried that several times – I can see it under disk utilities but it won’t remount.

It is 4 seagate drives in 2 Seritek enclosures.

Any help is greatly appreciated.

I’m just about to purchase this same set-up, now I’m scared! At $469.00 plus the drives it seems like a great storage option. Any one know of other solutions in this price point? Any comments on the Firmtek?

I was capturing footage last night and it locked up – now the raid won’t mount

[Torrey Loomis]

Shawn,

Please forward some information on your setup:

1. OS Version

2. Kind of SATA card

dual powermac g5 2.5 running OS X 10.3.9

and a Seri-Tek 1VE4

Thanks – I’m about at wits end

[Torrey Loomis]

Shawn,

I have clients who have been very happy with that card, but…

I would get off 10.3.9 immediately. Upgrade to 10.4 and see if it resolves. There have been a lot of reported problems with 10.3.9.

Example–Blackmagic will not support any of their cards running on a 10.3.9 based system.

I am terribly sorry to hear about this but to all of those who are considering this setup – it is a RAID 0 and RAID 0 gives NO security if one of the drives in the set fails in any way. Just the same for a Firewire RAID (if it is a software RAID setup)

The two or four stripe (disk) is a fast and inexpensive way to get around purchasing a very expensive RAID 3 or 5, but it is capable of robbing you of any and all of the data on those disks.

I would never recommend that you store ANYTHING on a software RAID that you can not retrieve from tape or other similar backup.

It has been my good fortune that my four stripe 1.0 TB of RAID 0 has never let me down, but it can and will, if you let it.

I had the same thing happen to me. I looked everywhere to find a RAID repair utility. Either it came with your RAID card or you used SoftRAID which has some options. Otherwise, I could find no utility that repairs RAID arrays. Looking at the low level of the drive mounting, I could see that one of my drive pairs was just set as something else — the data could have been fine. I still think it was a simple drive identifier that got set wrong. But since one drive was still “RAID” and the other wasn’t, the pair wouldn’t mount. Using “Data Rescue X” I was able to get some of the files recovered, even though it isn’t designed for RAID (it had to be looking at one drive at a time). Diskwarrior and other utilties did nothing.

There could be something to repair the drive settings out there … but I haven’t found it. I had to reformat the drives. They work fine now. But when I do a RAID again, I’ll probably use SoftRAID, or find a device that features some repair options. I believe the RocketRaid sports a repair tool.

good luck.

Thanks Guys for your input.

I wrestled with Apple’s and Seritek’s people with this for about a day and a half.

Then a good guy at Apple mentioned DiscWarrior. $90 bucks and the problem was solved in about 30 minutes with only a few clips lost.

what a relief!
