      It's hard to reproduce... usually it happens only on slaves... We create a new database every day... and there were no problems since december... and then it could not create/replicate files from in db: ZZZZZZ-160130 (30.I.2016) at midnight.

      That means, on previous days, there were no problems with permissions.

      And now the same problem with ./diagnostic.data/ means – the issue still presists in 3.2.1...

      Same problem as described here:
      https://jira.mongodb.org/browse/SERVER-20235

      This time:
      upgrade from MongoDB 3.0.3 to 3.2.1
      after upgrade & restart - mongo can't write to ./diagnostic.data/ (no x attribute/permission):

      $ ls -la /ssd/mongodb-wt/diagnostic.data/
razem 8
drw-r-xr-x  2 mongodb nogroup 4096 lut  3 14:13 .
drwxr-xr-x 18 mongodb mongodb 4096 lut  3 14:30 ..

      Context mongodb.log in attachement.

      Most important lines:

      and then:
