Resolution

 

Here you have three partitions in the Hard Disk, one is active partition, one is
inactive partition, the third one is common partition which is for log/trace
store.
 
This error message indicates that you are having the log stored in common
partition
 
To resolve this issue you need to delete the unnecessary log files:
For that
  • Open the RTMT plugin installed on the local Machine
  • Give the IP address and Credentials of the CUCM
  • Navigate to Trace and Log Central and click on Remote Browse
  • Select Crash Dumps radio button and click Next

  • Check Cisco CTIManager and Cisco CallManager.
  • Click Next and Finish.
  • Here you can select the log files and Click on Delete Button and remove them.

 

Also, disabling the traces which are not required and lowering the debug level for the enabled traces would also help.

Hi 

I am getting the above error and tried the solution mentioned, but still get the alert and the disk usage is still high(94%). Can you advise?

Hi Diana

Thanks for your reply I was on leave and just came back. I opened the link you posted and didn't know if I have to increase the number of the maximum number of files or to minimize it? 

 

Thanks again

Hi Ali,

 

I would verify those numbers aren't higher then the default settings.  In my case, I was coming across the same error / issue - LogPartitionLowWaterMarkExceeded UsedDiskSpace : 90.

It turned out the Maximum No. of Files was set alot higher then the default #, therefore the Disk Usage alert was triggered constantly.  Lowering both the High/Low WaterMark exceeded threshold helped but only temporarily.

It wasn't until I adjusted the number of trace files that are kept to avoid hitting the low water mark again.

 

Hope this helps!

Hi Diana,

I have performed above mentioned steps but it only reduced 6% of disk space.

The current status is as below.
