mdadm -E tells me e.g. for md1:

/dev/sdh1:
Events : 206286

/dev/sdf1:
Events : 206273

/dev/sdi1:
Events : 197114

/dev/sdj1:
Events : 206286
[...]


So all 4 disks see some diff state. Any chance on getting raid5
running again and read some data from it?

Does the mdadm -C --assume-clean option help me in that case anyhow?

Just add --force the to --assemble command.

I think I'd assemble from only 3 drives, sdh, sdf and sdj, because sdi's event count is so much lower it must be the one that was knocked out first and you probably want to resync onto it (or a fresh drive if it's actually faulty).

Cheers,

John.
