CDM probe is generating the below alarm even though the E: drive has enough free space, additionally the monitoring of the C: & D: drives is correct with no false alarms.
Average (1 samples) disk free on E:\ is now 0MB, which is below the error threshold (10MB) out of total size 0.0 GB
Based on the provided logs:
Mar 11 10:51:47:225 [14608] cdm: Drive E:\ - type '3'
Mar 11 10:51:47:225 [14608] cdm: Error from get_disk_free_space/GetDiskFreeSpaceEx: Access is denied.
Mar 11 10:51:47:225 [14608] cdm: Error from get_disk_free_space/GetDiskFreeSpace: Access is denied.
Access is denied is the reason cdm can't get the disk free info for E: drive.
Release : 20.3
Component : UIM - CDM WITH IOSTAT
The OS team reapplied the access to the E:\ disk which resolved the issue
