The /opt directory is showing 73% used on my ISE node. I have tried running the following commands, but the disk usage is still showing the same.
application configuration ise
[1]Reset M&T Session Database
[2]Rebuild M&T Unusable Indexes
[3]Purge M&T Operational Data
[4]Reset M&T Database
Is there command I can run that will free up disk space?
Internal filesystems:
/ : 34% used ( 4705772 of 14987616)
/dev : 0% used ( 0 of 8124300)
/dev/shm : 0% used ( 0 of 8134308)

/run/user/303 : 0% used ( 0 of 1626864)
/run/user/322 : 0% used ( 0 of 1626864)
all internal filesystems have sufficient free space

Please raise a TAC case and they can help you free up the space

ISE 2.2 has "issues" with managing its own disk space and it's completely out of the control of the normal user. *groan*
I have a customer whose ISE 2.2 system will periodically crash approximately twice a year because the system fills up due to bugs, logs and core dumps. System is completely unusable when this happens. Each time TAC tells us that the problem is bug x, fixed in release [insert_latest_at_the_time]. When this happens in 6 months again, the bug will be a different one again, and the fix will be release [insert_latest_here] - it makes no sense to me. The partitioning is so arcane, that a process core dump can push the Linux system over the edge and cause a complete outage.
Luckily I have not seen this in ISE 2.4 or later.
Ever since I can remember administering a unix system over 25 years ago, running a daily system check using cron can be used to clean out the junk to make sure this never happens. Cisco denies us the right to perform basic system admin on ISE. It would be a sad indictment if users had to take matters into their own hands, but I think we could at least reduce the amount of time wasted on TAC cases, when the TAC could be doing more serious things.

We previously hit a similar bug and needed to ultimately re-image our nodes
