Thanks a lot for your help!
Rebooting the system didn’t solve the problem, /dev/sdc is still nowhere to be found.
So I will have to replace /dev/sdc.
I tried to learn a bit about SRC/ERC from list archives, and it seems like my hard drives (1TB Seagate Barracuda’s) don’t support this option:
# smartctl -l scterc /dev/sdb
smartctl 6.0 2012-10-10 r3643 [x86_64-linux-3.7.10-1.45-desktop] (SUSE RPM)

SCT Error Recovery Control command not supported
I've got Seagate Barracudas (the 3TB version) and was a bit miffed to
realise that they didn't support this. That said, with mirrored 1TB
drives, you shouldn't have any real problems with SRC/ERC - the problem
is that a drive that returns 1 error per 10TB read is within spec, if
your array is over that size, then "good" drives could well cause a
crashed array if you have any glitches. (It seems that most drives are
well over spec, but why run the risk).
If you're price-conscious, WD Reds are not much more expensive than
Barracudas, and are advertised as "good for RAID". I'm looking at them
for my next hard drives.
Cheers,
Wol
