Multiple issues - unable to write to cache, /var/log full

Featured Replies

Hello, hope someone is able to help me figure this one out.  I've been having the /var/log full error for a bit of time now; rebooting always kicks the can down the road for a month or two.  But now that error is being coupled with some other ones, and I'm not sure where to start looking.  Attached is my diagnostics, thanks in advance.

Cache filesystem is fully allocated so you need to re-balance to free up some unallocated space for new metadata chunks to be created, more info below:

On a side note there's a very high metadata usage compared to data, not that this is necessarily bad, just unusual, do you have a lot small of files up to 2KB?

Thanks, I thought I cleared out a decent chunk of space (~100GB) but maybe I'm wrong there.  For the high metadata, could that be from Plex?

The problem is not free space, it's free unallocated space.

Possibly, I don't use it but remember reading it uses a lot of small files.
