hi folks,

what's the safest way to get this array back into r/o mode?

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

You missed a "/dev" there!

Did you try just giving all the devices to mdadm and letting it pick the best?

 mdadm --assemble --force /dev/md0 /dev/sd[defg]1

?
