Unable to write to log - space issue

As noted in the OSX thread I am having issues spinning up VMs. When I look at the main dashboard my cache SSD has 80GB free on it. Yet when I run "df" I see this:-

which looks like there is no room in /var/log and also no room in /dev/sdf1 which appears to be the cache drive. So a little confused....anyone got any ideas?

It takes quite a long time for unRaid under normal circumstances to fill the log...  You're most likely getting a ton of errors being logged.  

 

Post your diagnostics

 

The easiest way to fix this (at least temporarily until you fix whatever is causing the errors) is a reboot

Try to get a diagnostic before and another after reboot. The one before will be incomplete if you can even get it, but it might have something in it that won't be there after reboot.

I think I might have got it all confused with the cache drive, I was trying to move some of the VM images to the array as I was running out of space but then I think I created a share without specifying no cache....

 

Anyway I moved them all off to an external drive, and re-created the shares and copied them back. I'll shout if I have any more issues. My log seems to full of DHCP stuff - I am running dnsmasq on my domain, unRAID is acting as a DHCP server (my router won't let me specify custom external DNS servers but will let me switch DHCP off/on). I need to see if I can stop it from spamming the log.

 

Thanks!
