Ugh, sounds like a disk hardware problem :-(. Better think about new
drives, or at least reformatting the one you have.
As a short-term workaround to be able to dump your DB, I'd suggest just
DROP INDEX pg_description_objoid_index;
(you'll have to set the magic switch that allows modification of system
tables first).
You could try reindexing pg_description, but since this is a highly
noncritical index, it's probably easier just to get rid of it.
