What's the smartctl -a output for both drives? You might have bad SATA
cables. Also smartctl -t long (takes 1 minute) might be worth it. Not
sure how useful that is on SSDs.

Thanks to me being at home and only IPMI access with relatively high
latencies, I did not manage to boot into single user mode and the system
booted up normally - luckily for me, both md and ext4 tell me, the file
system is safe and ok.

I think I got really lucky (still running checks on the git repositories
on this md).

Anyone who experienced such a problem with SSDs (or HDDs) being
disconnected like this?

Cheers
