This is at least the second time this happened- all at once, four of the drives report as 'removed' when none of them actually were.

We bought 16 of them as an upgrade for a hardware RAID originally, because the tech from that company said they would work fine. After running them for a while, four drives dropped out of that array. So I put them in the software RAID expansion chassis they are in now, thinking I might have better luck. In this configuration, this happened once before. That time, the drives looked to all have significant numbers of bad sectors, so I got those ones replaced and thought that that might have been the problem all along. Now it has happened again. So I have two fairly predictable questions and I'm hoping someone might be able to offer a suggestion: >> >> 1) Any ideas on how to get this array working again without starting from scratch?

Once I power cycled the disk expansion enclosure and rebooted, all the drives were recognized by the OS. Last time this happened, the same thing occurred. Once I cycled the enclosure and rebooted, all the drives seemed to work OK. I was immediately able to reformat them and recreate the array, so it's more like something is causing a glitch rather than the drives actually permanently failing. Below is the output from smartctl and the section of the 'messages' log from when I tried to mount and use the disk array and it's failure. I will look through the other system files and see if I can post anything from them also. This is a long enough post as is. Sorry. I'm not sure what info on these will help or I'd condense it. Thanks again, Eli Here is the 'smartctl -a' output for the four bad drives: [root@stratus ~]# smartctl -a /dev/sdb smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Green family Device Model: WDC WD20EADS-32S2B0 Serial Number: WD-WCAVY0634185 Firmware Version: 01.00A01 User Capacity: 2,000,398,934,016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Wed Dec 7 12:56:38 2011 PST SMART support is: Available - device has SMART capability.
