From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2 i686; en-US; rv:0.9) Gecko/20010507 Description of problem: fsck doesn't notice that RAID devices live on the same disks, and checks them in parallel. How reproducible: Always Steps to Reproduce: 1.Create multiple RAID devices, each using one partition from the same set of disks. 2.Press the reset switch. 3.Note how it checks all RAID devices in parallel. Actual Results: fsck takes a long time to complete, and the disks' heads move like crazy. Expected Results: RAID devices built off partitions in the same disks should be serialized. Additional info: I've worked around the problem by using increasing fs_passno numbers.
e2fsprogs-1.22 treat all md devices to be on the same harddisk, so at least multiple raid devices don't get checked at the same time. So partial solutions are implemented, the passno configuration should be used to fix other setups. Thanks, Florian La Roche
