 ### I am getting an error: Database disk image is malformed. ###
 This means your sqlite database that stores most of the information for Sonarr is corrupt. There is an excellent guide here to copy the contents from the corrupt database into a new one: http://techblog.dorogin.com/2011/05/sqliteexception-database-disk-image-is.html
 
+If you are using mergerFS you need to remove `direct_io` as sqlite uses mmap which isn't supported by `direct_io` as explained in the mergerFS [docs here](https://github.com/trapexit/mergerfs#plex-doesnt-work-with-mergerfs)

 ### Why does Sonarr refresh series information so frequently? ###
 
 Sonarr refreshes series and episode information in addition to rescanning the disk for files every 12 hours. This might seem aggressive, but is a very important process. The data refresh from our TVDB proxy is important, because new episode information is synced down, air dates, number of episodes, status (continuing/ended). Even shows that aren't airing are being updated with new information.
