After power failure, 2 MongoDB Servers just won't start again.
With one I get: :

WiredTiger error (0) [1500732904:16506][17102:0x7fc3ddb5bdc0], file:WiredTiger.wt, WT_CURSOR.next: read checksum error for 12288B block at offset 2478080: block header checksum of 405166289 doesn't match expected checksum of 439830749

Would you be willing to try repairing our .wt files for both our servers separated by 2 set of files that i've attached
Thanks
