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reconstruction Rescue Kernel: md: raid1: raid set md1 active with 2 out of 2 mirrors Rescue Kernel: md1: bitmap file is out of date (148 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 149) -- forcing full recovery Rescue Kernel: md1: bitmap file is out of date, doing full recovery Rescue Kernel: md1: bitmap initialisation failed: -5 Rescue Kernel: md1: failed to create bitmap (-5) That's it for the log, then on the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?
