CONTAP-414670: CM quota system deletes all CCMA files after reboot when CCMA file space exceeds limit
Issue
After a node reboot, some of CCMA files were missing, preventing performance archive collection.
The problem occurs when CCMA file space exceeds the configured limit — upon reboot, the ONTAP CM quota system removes some of CCMA files instead of older ones only.
This impacts troubleshooting because performance data is lost.
