IMHO on md1 component sdb2 of raid is failing. Try rebuild using
mdadm. First remove the raid component sdb2 from md1 and then add it
back again. Some times the raid parity fails due to improper shutdowns
and when you re-build it is restored properly. If it does not it is
likely your disk is developing errors. Be aware! Carefully man mdadm
for details before you do anything.
