Package: mdadm
Version: 2.6.9-3
Severity: grave
--- Please enter the report below this line. ---
Hi,
With kernels newer than 2.6.26-2 (I have tried both 2.6.29-2 and 2.6.30-1)
mdadm fails to assemble raid array on boot:
Assembling all MD arrays... md: md0 stopped
mdadm: no devices found for /dev/md0
Failure: failed to assemble all arrays.
After the system gives up waiting for the root device, I get an initramfs
shell, and then I when I try to build the raid-array myself, using either:
mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sda2 /dev/sdb2
or
mdadm -A /dev/md0 /dev/sda2 /dev/sdb2
it fails saying that /dev/sda2 and /dev/sdb2 are busy (mdadm: Cannot open
/dev/sda2: Device or resource busy).
Please tell me if there is any more information I can provide that could be of
help.
Thank you,
Lior
