Update: a hard reboot worked, the raid was visible but inactive.
We re-added the now checked sdf (in a completely cleaned server) and the
raid was still inactive. In the end I had to re-assemble the md-device
with 5 out of 6 devices, right now it rebuilds:
# cat /proc/mdstat
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4]

I assume that I will simply have to add /dev/sdf4 then ??
Or again "add" and then "grow" ?
The PV/VG/LVs all are valid, time to try to relax a bit now.
Thanks, Neil,
