I have a raid 5 device created with
mdadm. I was working on it and long story short, I wanted to type
mdadm --manage /dev/md127 -a /dev/sdd, but I accidentally typed
mdadm --manage /dev/md127 -a /dev/md127 -a /dev/sdd which added the raid as a spare drive to itself.
Number Major Minor RaidDevice State 4 8 32 0 active sync /dev/sdc 1 8 16 1 active sync /dev/sdb - 0 0 2 removed 3 9 127 - spare /dev/md127
Now the raid isn't working properly. I cannot seem to kill it, and my attempts to decrypt it have just ended with the computer hanging with
^C doing nothing.
So my question is this: Is there a way to fix this? I have tried moving the raid to another computer, and restarting the computer and building the raid with
mdadm --assemble /dev/md0 /dev/sd[b-c]. Neither of these worked.
