On my new PC with open SuSE 11.0 I’m having the following problem:
While trying to start one of my software raid1 arrays I’m getting:
$ mdadm -R /dev/md1
mdadm: failed to run array /dev/md1: Input/output error
dmesg at that time shows:
md1: failed to create bitmap (-5)
md: pers->run() failed …
mdadm -Q, -E and -X don’t show anything wrong except that disk in array are out of sync.
These are new disks and I don’t think there are anything physically wrong with them. smartctl doesn’t show anything suspicious, dmesg don’t tell anything except what said above.
The only clue that it’s something with software is:
$ mdadm -E /dev/sdb3
…
Internal Bitmap : -175 sectors from superblock
I wondering if it could be something like this:
Re: mdadm 2.6.x regression, fails creation of raid1 w/ v1.0 sb and inter
Can anyone confirm if that bug is fixed in current kernel or not?
Any other ideas?
