I had this exact same problem about a year ago. In that problem my /var was only 6.8Gb in size. After I re-sized partitions (NTFS and /var) my /var was (and is) 14Gb in size. It too has completely filled up.
I discovered this problem this morning when I tried to install an update, it failed as /var was full.
So I'm at a standstill as I can't install anything, as any update gets temporarily stored in /var. also I can't print anything for the same reason.
Using Dolphin I found this.
The main culprits are 3 folders I have found so far:
/var/log - 3.9Gb
I can't see anything specific in /var/log taking up 3.9Gb, but there are some folders I can't access via Dolphin.
/var/lib/plexmediaserver - 3Gb (I expected this but I need to keep that)
/var/spool/mail/ there is something called "root" that is 3.7Gb big.
I'm not sure what other type of info you might need to help me out with this.
So what is going on, /var is twice the size now. Why are /log and /spool so huge?????
I don't want to have to go through the rigmarole of re-sizing all the time, that seems ridiculous. I obviously don't have something set up properly to manage data going into /var, but don't know what that is.
I should say I am using Dolphin to do this, I'm not a CLI-type of guy.
As always, any help greatly appreciated.
