      Hey,
      I have installed mongodb using `apt-get install mongodb`.
      Then I copied the whole directory `/var/lib/mongodb` to another instance and tried to use `wiredtiger` python package. When I tried to open the directory, I got Segmentation Fault

      I ran those commands:

      In [1]: import wiredtiger

In [2]: wiredtiger.wiredtiger_open("/var/lib/mongodb/", "readonly")
application error event handler failed: Operation not permitted
WiredTiger Error: Invalid argument: Error parsing '(1,0)' at offset 94489280512: Unexpected character
[1603617984:313778][10864:0x7f348ea33740], txn-recover: __wt_txn_recover, 712: Recovery failed: Invalid argument
corrupted size vs. prev_size
Aborted (core dumped)

      Link to tar.gz of the mongodb directory:
