How to Clear space on the / mount on Linux (Openfiler NAS Install - rpath)

Hi Guys,

I have a customer that installed a version of Openfiler 2.99 as a VM on an ESXi Server, he has a little bit of IT knowledge which as we all know gets people in trouble.

Anyway all has been going well with this install but the other day he rang and said the shares had stopped working getting errors when he tried to access them from his windows server.

I started to have a look around and eventually found that the / mount was 100% which i am sure might be causiung the issue.

Anyway as i am not a Linux Expert, i need some help in clearing space.

When i have setup these in the past advise given to me by my Linux expert which i cant get in touch with at the moment was always to make a /var/log mount for all the logs to go into rather then letting logs build up in the / mount and i presume getting in trouble like this.

My Customer did not set this up when he installed openfiler at the start so my understanding is that all his log files are going into the / mount which might have filled up.

I can use WinSCP to get into the Install and can see everything but i am unsure what to delete/move etc

Can someone please let me know how to handle this.

Thanks Adam
