ch@snaggle:~$ sudo mdadm --examine /dev/sd[defg]1 | egrep 'Event|^/dev/sd'
/dev/sdd1:
Events : 286024
/dev/sde1:
Events : 286011
/dev/sdf1:
Events : 286024
/dev/sdg1:
Events : 286024
ch@snaggle:~$ sudo mdadm --assemble --force /dev/md0 /dev/sdd1
/dev/sde1 /sdg1
mdadm: cannot open device /sdg1: No such file or directory
mdadm: /sdg1 has no superblock - assembly aborted
I'm no expert on this, but two questions:
Did you mean /dev/sdg1 ?
Why not use sdd1, sdf1 and sdg1 since they have the correct event counts?
Then add sde1 and allow to resync?
sudo mdadm --manage /dev/md0 --stop
sudo mdadm --assemble /dev/md0 /dev/sd[dfg]1
sudo mdadm --manage /dev/md0 --run
Try that, and provide any output
PS, it seems you would only need a minimum of 2 drives, and you have
three with matching event counts, so it should be fine.
Regards,
Adam
