As explained earlier.
One disk died. As I was replacing the disk and it started rebuilding,
a faulty Sata cable made that a 2nd disk got disconnected.
Mdadm immediately turned off all access to the disks. I rebooted after
replacing the sata cable. Obviously it refused to restart the raid as
for a short time, two disks were missing.
I forced re-adding the drive, and continued repairing the RAID.
I lost some data, but nothing major.
There's no way I would have recovered anything with a hardware raid card.
md is amazing.
