System volume root's usage is 92%.
Hello All,
I have been getting the "Volume: System volume root's usage is 92%..." message for a few weeks. It started at about 81%. When it reached 92% I uninstalled all the apps ( I had installed e few over the years. The latest was was Plex media server, which i had not actually used) and it has not gone up since. I am new at this and I do not know much about the file structure and what it should look like. I have enabled SSH on the NAS and installed Putty. It seems that the solution is to delete the large files but I do not know where to start and how to do it. I am on the latest firmware 6.6.0.
Any help and guidance would be greatly appreciated.
Here are a few listings from putty:

This is now resolved. MySQL and apps that were using it have been removed.

Well what's under /var/lib ?
# du -csh /var/lib/*
If it's say a large MySQL database it is possible to move the databases to the data volume and use a symlink to the location on the data volume.Yes it is a mysql file that is gorwing. I think it has stopped growing, probably after I uninstalled all the applications. It looks like it is the ibdata1 file that is the problem. Do you know what is stored in this db file? Is it possible to purge the content of the file without ill effect? Or is it better to do as you suggest?
I'm a newbie but I can follow instructions.
Thank you very much for your help!
