Mikael,
Following the commands:
# mdadm --stop /dev/md1
# mdadm --assemble --force /dev/dm1 /dev/sd[ab]5
The messages captured in the logs are:
Rescue Kernel: md: md1: stopped.
Rescue Kernel: md: unbind<sda5>
Rescue Kernel: md: export_rdev(sda5)
Rescue Kernel: md: unbind<sdb5>
Rescue Kernel: md: export_rdev(sdb5)
Rescue Kernel: md: md1: stopped.
Rescue Kernel: md: md1 raid array is not clean -- starting background reconstruction
Rescue Kernel: md: raid1: raid set md1 active with 2 out of 2 mirrors
Rescue Kernel: md1: bitmap file is out of date (148 < 149) -- forcing full recovery
Rescue Kernel: md1: bitmap file is out of date, doing full recovery
Rescue Kernel: md1: bitmap initialisation failed: -5
Rescue Kernel: md1: failed to create bitmap (-5)
That's it for the log, then on the command line I have:
mdadm: failed to RUN_ARRAY /dev/md1: Input/Output error
What should I try next? Don't hesitate to ask if you need any additional
information, I'll provide whatever is necessary. Thanks.
