vShield Manager: "/" is out of space

Hi,

"vCenter Operation Manager" shows this alert ("/" is out of space), and from the console of "vShield Manager", and when I run the command "show filesystems" I see:

I opened a support case with VMware. But I haven't get an answer yet.

I've found this link: http://www.vstrong.info/2012/10/29/vshield-manager-stopped-working/

Did someone have the same problem? and have purged the log? How could I prevent this problem, or monitor the free space at vShield Manger?

I don't know how to access the filesystem, like in Linux.

Any comments, will be appreciated.
