I'm still reading email with plain ascii most of the time, I don't care for HTML email generally since it just gets in the way. sylvain> Back to the issue : sylvain> I have stop the raid. sylvain> mdadm --stop /dev/md2 sylvain> mdadm: stopped /dev/md2 sylvain> cat /proc/mdstat sylvain> Personalities : [raid1] [raid6] [raid5] [raid4] sylvain> unused devices: <none> sylvain> And when i try to re-assemble, the command is aborting : sylvain> mdadm --assemble --force /dev/md2 /dev/sd[bcde]1 sylvain> mdadm: /dev/md2 assembled from 2 drives and 1 spare - not enough to start the array. So if I look at the event counts, there's a mismatch between /dev/sd[bde]1 and /dev/sdc1. So let's try to assemble without /dev/sdc1: mdadm -vv --assemble --force /dev/md2 /dev/sdb1 missing /dev/sdd1 /dev/sde1 and see what happens then. With three out of the four devices, the RAID5 array should start up, and then you can add in /dev/sdc1 to rebuild the parity.
