 Description   

I am attempting to repair a corrupted db, but --repair doesn't work. I have also tried salvage with the wt tool. These are the errors:

[1570846069:870738][86561:0x7f6d231e0740], file:WiredTiger.wt, WT_CURSOR.next: read checksum error for 16384B block at offset 86016: calculated block checksum of 1998645344 doesn't match expected checksum of 1386055393

lt-wt: WT_PANIC: WiredTiger library panic

 

I have attached WiredTiger.wt and WiredTiger.turtle. Any help would be appreciated.

Thanks,
Qicai

I've resolved,because the db version is too low.By upgrade the mongo server and --repair,the problem is resolved.

Thanks!
