Title: Raid problem
Post by: slowboat on January 28, 2010, 02:07:00 PM

Hi

I get the following problem with the raid setup on 7.4, the check I ran on md2 says there's a fault but the check on md1 says its fine, is this a partitioning problem, can it be rebuild?:

Hi

try to add your sdb2 partition to the array with

Code: [Select]

mdadm -a /dev/md2  /dev/sdb2

and check /var/log/messages for errors

ion the meanwhile, buy a new hd :-)
