From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922 Description of problem: Reported via IT#53591 Customer: IBM-IGS/HSBC Bank Brazil RHEL 3 bugzilla # 141091 If you have a mirrored raid device ( raid level 1 ), and one disk encounters fatal errors, the raid device continues to operate on the other disk, as expected. However if the device is stopped and restarted then the raidstart will fail if the failing hardware is the first listed in the raidtab ( e.g. raid-disk 0 ). If the first raid-disk is operational, then the md device will start irrespective of the status of the second raid-disk. The customer encountered the problem on an EMC array; it is also recreated using my test machine on both AS2.1 and RHEL 3. The problem seems to be with raidstart, which only attempts the first listed disk irrespective of the raid level. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. (see bugzilla 141091 for details) 2. 3. Additional info: IT ticket is opened against AS2.1 but I did all the testing/verification on RHEL 3. Customer expects the problem being fixed both on AS2.1 and RHEL 3.
