I am wondering if someone might be able to help by outlining a proper protocol for troubleshooting and rebuilding this array (proc/mdstat below). Here is how I might approach it: - remove the device - test the device - if the device tests OK then re add the device - if the device fails, then replace the device - resync Thank-you for your consideration. Best, - Justin Here is the mdstat email ----------------- This is an automatically generated mail message from mdadm running on BigBlue A Fail event had been detected on md device /dev/md0. It could be related to component device /dev/sdh1. Faithfully yours, etc. P.S. The /proc/mdstat file currently contains the following: Personalities : [raid6] [raid5] [raid4] md0 : active raid6 sdh1[5](F) sdg1[4] sdf1[3] sde1[2] sdd1[1] sdb1[6] sdc1[0] 14650666880 blocks super 1.2 level 6, 128k chunk, algorithm 2 [7/6] [UUUUU_U] unused devices: -------- Justin Stephenson Creative Director/Motion Designer 416-900-6069 http://justinstephenson.com
