Adaptec RAID 2405 degraded RAID 10 array
Hi, since a few days I have some problems with a RAID 10 array on a
adaptec RAID 2405 card. I've been using this setup for about 10 months without any problems, but 4 days ago when I turned on my computer I go a message saying that my RAID array was degraded. In windows using adaptec storage manager I saw that the array was been rebuilded. It took 2 or 3 hours and everything was back to normal, the hard drive that had a exclamation point in storage manager looked fine and I don't seem to have lost any data. At this time I thought that it may have been an isolated event maybe due to the fact that my computer crashed (hang) a few minutes before. But 2 days after I got the same message (no crash or anything unusual), but this time another drive had the question mark on it in storage manager. I waited for the rebuild and everything was back to normal. Here's some informations I took from storage manager: First time: group 0 segment 1 controller 1, connector 0, device 1 Rebuilding... Second time: group 1 segment 1 controller 1, connector 0, device 2 Rebuilding... Right now I don't have access to the card BIOS so I can't give the BIOS version and settings (I think if my memory is correct that I have enabled write cache, which I know could cause some problems). I will send this information in another post soon. I have many questions: - Is this behaviour normal? Can an array loose it's synch sometimes (after a crash or a power failure) and need to be rebuild? - Since all drives are working correctly after rebuild and that 2 different drives had the problem, am I right to think that the problem is not due to faulty drives? - Can it be caused by a power supply power problem? A few days before I added a secondary graphic card, a MATROX G450 quad, but I'm pretty sure I have enough power since my power supply can deliver 850W (see specs bellow). right now I have removed the MATROX card just in case - I'm wandering, are group 0 segment 1 and group 1 segment 1 2 HDs containing the same information? If it's the case I find it strange that at some point one HD was being rebuild from the other, and that 2 days after this hard drive was rebuild from the first faulty HD. How do group and segment works? - Can the card, knowing there was a problem, rebuilt the first half of my array and 2 days later continue to fix the other half? - Is there any danger to loose everything when something like that happens? - The MATROX card was sitting just on top of the adaptec card with his heat sink facing the adaptec card, can heat be a problem? - Someone else ever experienced a behavior like this with his RAID array? For the moment I removed the MATROX card and did a complete backup of the system just in case. I will contact adaptec soon. Here's my system specs OS: Windows XP 32bits SP2 motherboard: ASUS PT6 Deluxe V2 CPU: Core i7 940 RAM: Corsair XMS3 Dominator 6GB DDR3 Power supply: Antec CP-850 (850 watts) Graphic card1: ASUS ENGTS250 1GD3 Graphic card2: Matrox G450-Quad Capture card: Diamond TV Wonder 650 Theater HDs: 4 x Western Digital RE3 32MB 1TB 7200 SATA RAID card: Adaptec RAID 2405 Misc: DVD burner/BR burner/some fans and fans controller I'm pretty sure that a 850 watt power supply has enough power to drive a system like this, or do you think it could cause some problems? Anyway all monitors on the MATROX were deactivated, the TV wonder was not in use, and I was not playing any games on the ASUS when the second problem arised But I was playing a game (not the latest GPU demanding game) on it when the computer crashed a fee minutes before the first problem. Any useful informations, tips or anything really will be greatly appreciated Thanks in advance |
