After upgrading to 3.2.8 (from 3.0.9) startup appears to hang with lots of disk reads to the local collection.
fatrace shows lots of:
mongod(87260): R /srv/mongodb/local/collection-2--6617514398526579318.wt
The file is a ~230gb file which is likely made up of the oplog.
This all happens after the log lines:
2016-07-25T13:12:15.345+0000 I STORAGE [initandlisten] Placing a marker at optime Jul 25 11:21:00:37f 2016-07-25T13:12:15.345+0000 I STORAGE [initandlisten] Placing a marker at optime Jul 25 12:55:11:25b 2016-07-25T13:12:25.296+0000 I NETWORK [websvr] admin web console waiting for connections on port 28017 2016-07-25T13:12:25.302+0000 I REPL [initandlisten] Did not find local voted for document at startup; NoMatchingDocument: Did not find replica set lastVote document in local.replset.election
and on another run with debug:

With verbose logging on it just shows WT Journal flushing at a regular rate.
Why is this happening and how long might it take for the node to come back online?
Will it try and read the whole collection / op log?
