Hi, thanks for your answer. (Tack!)
My debian mdadm is ver v3.1.4 - 31st August 2010
mdadm --assemble --force /dev/md0 /dev/sd[bcde]
outputs
mdadm: cannot open device /dev/sdb: Device or resource busy
mdadm: /dev/sdb has no superblock - assembly aborted
I compiled the latest mdadm v3.3.2 - 21st August 2014
running
mdadm --assemble --force /dev/md0 /dev/sd[bcde]
outputs
mdadm: /dev/sdb is busy - skipping
mdadm: /dev/sdc is busy - skipping
mdadm: /dev/sdd is busy - skipping
mdadm: /dev/sde is busy - skipping
Strange. What does this mean? Is it flaged as in use in the kernel? The
devices are readable, I tried to read data with
dd if=/dev/sdb of=dump bs=1024 count=1024
and it works, so the device is accressible.
dmesg shows nothing
/proc/mdstat

*** PLEASE advice ***
Please post dmesg output from when you do --assemble --force, and also
please post your mdadm and kernel versions.
As a first step, compile mdadm from source and use that version, it
often helps as distributions don't generally ship with the latest mdadm.
