Large Temp folder

[zrowley]

I noticed my HD was almost full and started looking into why. I cleared some cache files from Plex Media Server and it helped but was not the main issue. I have found a large temp folder under /var/sentora/temp that is taking 90G of space. I have searched and cannot find why this file is so large and what it is for. I don't have room for additional drives and don't have money to buy larger drives for the OS.

Any help would be appreciated.

Hi,

I think it's related to plex media server. are you watching high quality video's?

/temp is used for caching by some apps, uploading files and all "temporary files" operations.

Yes most of the media is HD and the files are pretty large. I cleared a few things on Plex which helped but isn't an issue anymore. The temp files are inside the Plex directories and shouldn't be storing data elsewhere. I am concerned specifically with the folder /var/sentora/temp  which is a total of 90GB.

I'm not sure over plex behaviour. You should check with them. For me I'm almost sure it's tightly related regarding file size. May re-encoding files. You can restart server and clear temp files but once you use plex it would sky-rocket again.

see here if you google a bit:

IT's not new nor a sentora issue.

Thanks for the suggestions. Here is what I have found:
The reason my temp folder was growing was due to old temp files related to my owncloud server that were not being deleted after they were no longer needed. I checked the last modified date of each file and anything that was more than 10 days old I manually deleted. After a reboot everything was running normally. A few days later I noticed in my log files for owncloud I was getting an error "Temporary directory not present or writeable". I must have accidently removed the temp folder all together and owncloud was not recreating it. So I created a new temp folder to see if sentora/owncloud would see it again and checked the owncloud log files to see if the error went away. It didn't so I changed the ownership of the directory "/var/sentora/temp" to www-data (apache user?) and the error went away. I read on owncloud forums that the owner of the temp folder was PHP-FPM but because I have Sentora installed I assumed it would require the apache user to own the temp folder which I believe is www-data. 

Can someone confirm the default owner of the temp folder for sentora? "/var/sentora/temp"

Yep apache should be the owner.
