High disk space utilization.

Dustin Anderson — Tue, 24 Oct 2017 16:03:40 GMT

Greetings,

After some googling, I think I found the issue, but not sure if I can delete it.

Now, this is a SNS-3595 that has 1.2TB of HD.

issue seems to be

Directory of disk:/corefiles/

Being in corefiles, I would guess it's mandatory, but what is it? I'm guessing /opt is the databases as that is where most of the storage is allocated.

Can that file be deleted, the repository increased, or how do I fix the error as it is every 4 min.

I would suggest to copy any core files to a repository and then you may safely delete them.

If core files generated frequently, please engage Cisco TAC to investigate.

Dustin Anderson — Tue, 24 Oct 2017 16:54:44 GMT

ok, thanks. Are they basically core dumps?

Yes, they are and from one of the java processes of ISE services.

Dustin Anderson — Tue, 24 Oct 2017 17:02:45 GMT

that makes sense, I've had a TAC open as ISE stops tracking sessions and license use. They had me install patch 1 to see if it corrects the issue.

Can you please confirm, is it safe to delete files in disk:/corefiles ?

My disk utilization is 95%, and I have a big file under /corefiles

Would recommend asking the TAC as they deal with these type of issues
