Not able to boot to my RAID devices. md0 is / and ext3 RAID1, but md1 and md2 are swap and JFS respectively, RAID10 created like this: mdadm --create /dev/md1 --level=raid10 --layout=o2 --metadata=1.2 --chunk=256 --raid-disks=2 missing /dev/sdb2 It gives the initial kernel boot message but then says invalid raid superblock magic on sdb2 invalid raid superblock magic on sdb3 ... and halts progress. I have to hard-reset to continue. Why isn't the error more specific? I've tried setting the metadata to 1.1, and tried adjusting mdadm.conf from /dev/md/1 to /dev/md1, but neither helped. The parts are set to raid autodetect and the kernel parameter is set to md_autodetect. What could be wrong?

I need to remove sdb1 from md0 so I can change it from a RAID10 to RAID1, and it simply ignores my command: > # mdadm /dev/md0 --fail /dev/sdb1 --remove /dev/sdb1 > # cat /proc/mdstat > Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] > md2 : active raid10 sdb3[1] > 1868560128 blocks super 1.2 64K chunks 2 offset-copies [2/1] [_U] > bitmap: 94/446 pages [376KB], 2048KB chunk > > md1 : active raid10 sdb2[1] > 6297344 blocks super 1.2 64K chunks 2 offset-copies [2/1] [_U] > bitmap: 0/25 pages [0KB], 128KB chunk > > md0 : active raid10 sdb1[1] > 78654080 blocks super 1.2 64K chunks 2 offset-copies [2/1] [_U] > bitmap: 76/151 pages [304KB], 256KB chunk > > unused devices: <none> > # > > > My system is half-converted and is now unbootable.
