A call manager server has just under 100MB of free space on the active & inactive partitions on both the Pub and Sub, CDR has been disabled and a manual purge performed (made no difference),tracing is at default settings and still unsure why utilization is so high. Customer had previously attempted an upgrade on the pub but reverted back and did not commence on the sub


Disk space allocated is 11Gb I checked out a fresh CM6 install and it only as total usage of 2GB of disk space.


Is there anything I can do, eg compact database or something like that?


Thanks

Hello Heath,


On most of CallManager 5.x/6.x systems, it's perfectly normal to see active partition use up to 96%-98% of disk space; since this partition contains the OS and CCM software, it's often very close to its maximum capacity.


The active partition indeed is pre-allocated (at the time you install the system) and it's, in normal conditions, not subject to strong file growth: for example, the DB space is also already pre-allocated there, even if most probably you are just using only a small part of it. The files subject to growth (e.g. logs) instead, are stored in different partitions just to avoid this problem.


To re-assure the issue, please check this BUG for further details:


- ID: CSCsi53145

Headline: RTMT LowActivePartitionAvailableDiskSpace raised after upgrade

Symptom: RTMT will display an LowActivePartitionAvailableDiskSpace alert indicating there is a low amount of disk space available in the active partition.

Conditions: This problem may happen after an upgrade.

Workaround: The Communication Manager is designed to run with very little available space in the active partition. Therefore, in most cases this alarm does not represent a problem. However, we have made additional disk space available in the 5.1(3) and 6.1 releases. If upgrading to these releases is not an option then it is possible to change the alarm threshold in RTMT.

The workaround is to set the LowActivePartitionAvailableDiskSpace Alarm in RTMT to a threshold of 2% (up to 2% is safe).


To do this:

- Go to RTMT.

- Open the tools tab at the bottom left of the screen, and select 'Alert Central'

- Find the 'LowActivePartitionAvailableDiskspace' parameter.

- Right-click on it and go to 'Properties'. Click next and on the next screen you can set the threshold to 2%.

- Click next two more times, then 'Activate'.



Hope this helps and clarifies the issue !
