Sync says "The disk is almost full' when it clearly is not

I am trying to sync movies on my iPad. In doing so, Plex seems to think the disk is full and refuses to finish the sync. This is very frustrating. Any ideas on how to fix this OTHER than completely reinstalling Plex and re-syncing several hundred GB of data??

I think I answered my own question and thought I would share. In the picture above, the “disk is full” comment must be referring to the disk where Plex is installed. Despite storing my movies on a large 8 TB drive, and having plenty of room on my iPad, there was limited space on the C drive where Plex was installed. Once I cleaned up the drive and freed up some space, this stopped happening. FWIW, Plex should really clarify WHICH disk is full, as the above warning is very misleading and confusing.

You’re almost right. It refers to the disk where you set your temporary transcoding folder. You can change it in the settings.

hum… thougth so too, but…
I’ve got the same message, 185Gb free on my iPhone and 62 Gb free on C where Plex is installed…
the movies I’m trying to sync are less than 20Gb each. usualy between 4 and 11Gb.
So? Where am I missing space!?

If you are trying to sync a group of movies, you need room on your PMS machine to hold the transcoded versions of all these files before they will transfer.

My computer has two drives. One is a SSD that only has 13.5 GB of space on it that houses the Plex program. I have a separate 8TB hard drive that has 1.11 TB of space on it. The first is my C:, the second is my E:. I have the transcoding folder as E:Temp that has 1.11 TB of space available. However, I am still getting the same message as listed above. What am I supposed to do?!?

Unfortunately, the Sync jobs do not use the transcoder folder. That’s specifically for live transcodes. Converted Sync files are save in “Plex Media Server\Cache\Transcode\Sync+” with the rest of the Plex data. This cannot natively be moved in PMS. You can replace that Sync+ folder with a hardlink to another location if you are familiar with doing that.

I am not, how do you do that?

Thi is the link to another forum discussion that I had found discussed that a little, but it all sounds greek to me:

Is anyone going to answer my question and help me?

I was really hoping to get this fixed in the next couple of days.

Hehe, I had the same problem, thought it was iOS specific (http://forums.plex.tv/discussion/264390/the-disk-is-almost-full-less-than-10gb-remaining).

Unfortunately I too can’t help you, I don’t know how to make symlinks in Windows (I think they’re called Junctions in Windows land), but Google may be able to help! It’s not the answer you want to hear, but hopefully points you in the right direction to resolve your issue.

What OS are you using? If it’s Windows I can help, if not I’ll have to get someone else. I don’t how make Symlinks on other platforms.

I spent 2-3 hours tonight trying to google how to do a hardlink. I tried to use mklink in CMD prompt to do it (running it as an administrator). I could create a /D symlink but it did not seem to work. It would not let me do a /H hardlink as it said it could not move it do a different drive. Then, I created a /J junction that worked, but I could still not Sync the movies. Both the symlink and the junction were set up but would not work.

I am trying to get info hard linked from C:\Users\Mez\AppData\Local\Plex Media Server\Cache\Transcode\Sync+ to E:\Temp\Sync+. The C: is a a SSD with only about 11 GB available anymore. The E: is a hard drive with about 1 TB space remaining.

You could always just move the PMS data directory to the larger hard drive. I have my Plex server data directory on a 250GB SSD. The location is set in the server settings under the general tab. You should be able to set the location, then shut down the Plex server application, move or copy the directory to the new location, then start the Plex server app again.

Did you remove the Sync+ folder from C:\Users\Mez\AppData\Local\Plex Media Server\Cache\Transcode\Sync+ first? This should work and what you want is a junction. You also need to create the destination, E:\Temp\Sync+, folder first too.

From the C:\Users\Mez\AppData\Local\Plex Media Server\Cache\Transcode, run the command:

mklink /j Sync+ E:\Temp\Sync+

Or from any other location

mklink /j “C:\Users\Mez\AppData\Local\Plex Media Server\Cache\Transcode\Sync+” E:\Temp\Sync+

Will that slow down normal transcoding and streaming since the SSD was to make this faster in the C:?

The other question I have is the Plex employee above said, or at least I understood it this way, that I couldn’t move the Sync folder but could only create a hardlink to the new location.
