"High Disk Space Utilization" on PAN/MnT node after ISE 2.2 patch 1 upgrade

[andrewswanson]

Hello

I'm getting Alarms "High Disk Space Utilization" after upgrading from ISE 2.1 patch 3 to ISE 2.2 patch 1.

There are 2 PAN/MnT nodes in the deployment:

The Primary Admin (secondary Monitoring) is showing 97% used on /localdisk - this node was upgraded from 2.1 (patch 3) to 2.2 (patch 1). It was at 100% but I deleted all the files I could from the repository (e.g. patches etc)

The Secondary Admin (primary Monitoring) is showing 11% used on /localdisk - after the upgrade to 2.2 I had to reimage this node so is a fresh install of 2.2 patch 1.

I was planning on re-imaging the current Primary Admin node to see if this solves the issue - has anyone else seen this happen after upgrading to 2.2? I carried out a purge of ISE data prior to the upgrade.

Thanks
Andy

I haven't experienced this specific issue, but I am curios, what do you see if you run "dir disk:/" on the Primary PAN?

Hi

The issue seems to have been resolved. I was getting ISE alarms every 5 minutes with localdisk at 100% on the primary PAN. I deleted the files present in the DISK repository (url disk:/) and the localdisk usage dropped to 97%. About 15 minutes later, PAN localdisk dropped to 12% and has stayed that way for the last 24 hours.

So it looks like clearing out the local DISK repository solved it - I'll monitor this over the next couple of days to make sure.

cheers
Andy
