Last night our mongodb server was crashed with the error message
" E STORAGE [WTCheckpointThread] WiredTiger error (0) [1536271010:760909][453:0x7f57298e9700], file:WiredTiger.wt, WT_SESSION.checkpoint: WiredTiger.turtle: encountered an illegal file format or internal value: (_wt_turtle_read, 293) Raw: [1536271010:760909][453:0x7f57298e9700], file:WiredTiger.wt, WT_SESSION.checkpoint: WiredTiger.turtle: encountered an illegal file format or internal value: (_wt_turtle_read, 293)"
Then I tried to restart the server and also run the mongod --repair command but I always get the same error. The log file and wire tiger files are attached. Thanks in advance for any help
