ISE 2.6 High Disk Utilization

[pnowikow]

Community,

I've been getting these "High Disk Utilization" alerts via email but when I check the actual disk space it's fine.  What else am I missing here?

CiscoISEVM01/admin# dir

Directory of disk:/

4096 Mar 22 2020 04:54:07 corefiles/
16384 Mar 22 2020 05:04:20 lost+found/

Usage for disk: filesystem
46166016 bytes total used
29193236480 bytes free
30829043712 bytes available

CiscoISEVM03/admin# dir

@Damien Miller This post had identified 2.4 patch 9 solving it but also needing TAC.  Since I'm on 2.6 but recently upgraded 2.3.

[Damien Miller]

You will have to engage TAC. I'm not certain what this docker is used for, but it's where the alarm is coming from.

/opt/docker/runtime/devicemapper/mnt/3f817894326c4d07cfff96c59ada1e0df1a5597ccefe3a2a747f5ccb4061a611

While the node is not out of disk space, the space allocated to this piece will still trigger than alarm.
