ceph-mds --reset-journal didn't work; it would deadlock waiting for
the osdmap. Comparing the init code in the Dumper (that worked) with
that in the Resetter (that didn't), I noticed the lock had to be
released before waiting for the osdmap.
Now the resetter works. However, both the resetter and the dumper
fail an assertion after they've performed their task; I didn't look
into it:

Allow specifying 'rep', 'raid4' and 'erasure'.
Only allow setting type 'erasure' if all up osds support erasure codes.

If OSDMap has the EC feature set, then update our superblock to
reflect as such, making our on-disk format incompatible with previous
OSDs without EC support.

Add the osd's features to the osd's extra info field in the OSDMap
so we can track which OSDs are able to deal with Erasure Codes.
This will allow us to decide whether or not we are ready to set EC
whenever the user asks us to set EC on a pool -- which shall be
handled by a subsequent commit.

the string error is found.
