Need help with RAID question. I think something is really screwed up!!!
I'll try to keep this brief.
I set up a new system (described below). The I set up a RAID 5 array using an external enclosure and four Western Digital WD5000YS (enterprise) drives. I set up the array and it worked. I loaded all my data to it. It worked. I loaded software to the system (to a non-raid drive on the built in controller, not the RAID controller). Everything worked fine. Yesterday the controller advised me that a drive in the array failed and that the "logical device degredated". I rebuilt the array. That took about 11 hours! Today, the same thing happened. All of a sudden, everything locked up for a minute and then the alarm went off. When I looked, a different drive caused an error. I had the drive rebuilt. When it was about 12% finished, the alarm went off again indicating another drive failure in a different drive. This time it couldn't rebuild since there were only two out of four drives remaining. My questions a 1. Am I doing something wrong? 2. Is there any way to force the controller to rebuild (as best it can) the array from the four drives? There is nothing wrong with any of them (even the controller says they are "optimal") 3. If I decide to abandon the idea of RAID (looking like a good idea from where I am standing), is there a decent 8 port SATA II controller? 4. Is there a way to use my RAID controller as a simple SATA II controller w/o RAID. That way if something does go wrong, I can use one of the zillion or so software tools to try and recover something. Now I basically have no options that I can see. Any insight would be greatly appreciated. -Jeff System specs: Tyan K8WE (s2895) motherboard Dual Opteron 285 CPUs (dual core) 4 GB RAM (registered ECC) Sound Blaster X-Fi sound card XFX 7900 GTX Video card Adaptec 2820SA Raid Controller (SATA II) Western Digital WD5000YS 500 GB SATA II drives (4 drives) External housing and multilane cable |

The enclosure came from PC-pitstop. The drives appear to be running
very cool. Also, the problem happened at a time when they were largely inactive. If it were heat / power I would suspect that when I loaded the data to the drives would have been a more likely time for failure. I am just about ready to move the drives internal (scrapping the housing / psu and cables) but I really liked the idea that the drives (and their inherent heat) were kept out of the chassis. Someone suggested the drives might be taking too long on an error and timing out the controller, but these drives have TLER and thus aren't supposed to cause such problems for RAID. -Jeff |
