That is not something it is safe to be playing with. If you are getting capacity warnings from the system you should open a support call.

While you CAN poke around inside the OVC now, that doesn't mean it is safe to do so. I have no idea what that LVM is used for, and the fact that it is full, absent an alarm, might not be an issue.

Thanks John for the reply. 

New case 5337480575 has been logged for OVC - are running out of disk space and they advise below.

recommended to take a backup of the file through winscp, delete the folder which will give us disk space in OVC and recreate it .

I'm hesistant with the solution they provide as it may break OVC VM.

/core is used for dumps  in the event of a crash the files gernerated are used for diagnostic purposes  and will persist across reboots.

The advice is good these files may be deleted without issue.Not sure if i would bother winscping the files most of them are old and the other logs used for diagnosise  will most likely have rotated,viewing the cores in isolation will not give a full picture.
