Xen 6.2 – how to free up space

xenserver

I have an HA pool of 3 Xen 6.2 machines. On each the root volume is > 90% full. I've updated the logrotate scripts to keep /var/log clean but have found that lots of space is taken up by /var/patch. In this folder are all the files (by UUID) uploaded to update the OS.

I'm wondering about clearing these out and what will happen. According to this page one can remove all the patch files with a single command.

My question: has anyone tried this? Any other strategies for freeing available space?

Came across this post on the xenserver site.

Essentially:

  1. Clean up patches once they are applied
  2. Watch for /var/log filling up
  3. Watch for /tmp
  4. Includes a handy script to notify you when disks are filling up
