From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: I created 3 raid partitions - md0, md1, md2. I remove md1 and try to swap md2 to md1. It doesn't work. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Create 3 'raid 1' partitions: md0, md1, md2 2. Remove /dev/md1 from /etc/raidtab 3. Change /dev/md2 to /dev/md1 in /etc/raidtab 4. Reboot the machine Actual Results: I see the message: Starting RAID devices: md0 md1 Checking Filesystem Could this be a zero-length partition ? fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/md1 Additional info: The partition that composes original /dev/md2 are no AUTORAID detection. Even though, it seems kernel starting the raid before it gets to the script ( rc.sysinit ). After the error I described above, when it jumps me to the prompt and I do a 'cat /proc/mdtstat', I see md0 and md2. I run 'raidstop /dev/md2' and then 'raidstart /dev/md1', look at 'cat /proc/mdstat' and md2 is there again !!!
