I am running Plex on a mac mini connected to an iSCSI Drive.
At this moment my local hdd is filled with about 140Gb of Data. I don’t want to store this data local. Is their a way to store the Meta Data on the Library Drive. Their is plenty free space to store the data and it is fast enough to access the files.
Plex does not want you to relocate the metadata to a network drive. Personally I suspect you could do it to an ISCSI drive and it would work fine but, there is definitely an increased risk of corruption.
Although my current setup does not require it as I have plenty of internal storage for my Plex data I have, in the past, used USB drives for Plex data without any problems. I always set up any drive to be used with Plex so it never sleeps or spins down and that means that the database is always accessible and that is what Plex needs.
Because of the way networks work drives attached through a network are unreliable for instant connection.
For similar reasons with pooling systems like “DrivePool” Plex’s data directory should never be in the pool.
