Last weekend I was moving a server with a raid1 configuration, controlled by a Intel Corporation 82801 SATA RAID Controller. Upon reboot I noticed the degraded message (server hadnt been rebooted in a couple years). The raid1 array was two 500gb black WD drives. I wasnt able to locate an identical 500gb disk, but did find a 2TB just to get things mirrored again. The bios screen accepted the replacement disk and said it would rebuild in the OS. mdsync seemed to do its thing but I noticed mdmon process was taking 200% cpu. I let it go a few days thinking it was just taking longer than normal to sync, then rebooted. It was in a complete failed state and wouldnt boot at all. After removing the 2TB disk I was able to boot into the OS again. I just assumed I needed a similar drive size for the second part of the mirror. Today I installed an identical black WD 500gb drive and its doing the same behavior. Currently running a bad block check but in the meantime I found the wiki and read up a bit on some basic troubleshooting and asking for help (https://raid.wiki.kernel.org/index.php/Asking_for_help) I wanted to attach the output of the commands on that page and hope someone may have some ideas for rebuilding this second drive. Thank you in advance for any suggestions. Im concerned at this point I only have one good drive and could possibly lose everything if that failed. mail:~ # smartctl --xall /dev/sda smartctl 6.0 2012-10-10 r3643 [i686-linux-3.1.10-1.29-pae] (SUSE RPM) Copyright (C) 2002-12, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Black Device Model: WDC WD5002AALX-00J37A0 Serial Number: WD-WMAYUL169523 LU WWN Device Id: 5 0014ee 104a23be3 Firmware Version: 15.01H15 User Capacity: 500,107,862,016 bytes [500 GB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s) Local Time is: Wed Apr 12 09:33:54 2017 EDT SMART support is: Available - device has SMART capability.
