I hava a replSet with 3 servers, there are with 300GB data, Last week, we suddenly had a power outage, when the power was restored, I restart my mongoDB successed, but when I cmd "show dbs;", I remeber it said like this:
WiredTiger (0) [1481884901:569933][7325:0x7f77131f8c20], file:collection/3-4162965380314250895.wt, session.open_cursor: read checksum error [4096B @ 32768, 239944241 != 3341820703]
So I hoped "mongod --repair" can help me to fix it, I use the repair cmd on 3 servers........
Surprisingly, it failed, the screen msg like this:
Fatal assertion 18506 DuplicateKey E11000 duplicate key error dup key:

How can I fix it? Please help me.
