[Bug 752869] md raid1 doesn't boot after removing 1 disk, when the server is turned off

https://bugzilla.novell.com/show_bug.cgi?id=752869 https://bugzilla.novell.com/show_bug.cgi?id=752869#c2 --- Comment #2 from Wilfred van Velzen 2012-03-21 15:38:39 UTC --- With the help of https://en.wikipedia.org/wiki/Mdadm, I found the right commands to (re)assemble the raid arrays in the emergency console, in this state:

mdadm --stop /dev/md0 mdadm --stop /dev/md2

mdadm --assemble /dev/md0 /dev/sda1 --run mdadm --add /dev/md0 /dev/sdb1 [repeated for all the arrays]

And wait for the synchronization to finish, before rebooting. Checking this with:

cat /proc/mdstat

So it isn't an unrecoverable state, but still rather inconvenient. Specially if the machine is at a co-location and you have to drive for a X amount of time to go to the location to find out what happend and fix it... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
