Hello Pros,

I am in process of upgrading CUCM from 8.6 to 9.1.2 and receiving "not enough disk space on the partition" error.

The show status from CLI shows 13499216K free space but I don't understand why we are getting the error message. I tried FTP and SFTP, from GUI and CLI with no luck.  Do I need to start deleting files (traces, firmwares, etc..)? Even if I do so it wil free up the space in active partition and change nothing in my inactive partition as all thoses files are in my active partition.  Your help is very much appreciated.

Usually the error indicates that you don't have enough space free on the common partition which is where logs are stored.  There is a fix for this, http://www.cisco.com/web/software/282204704/108295/ciscocm.free_common_space_v1.1.pdf. ; I would try this as your next step if the description in the readme matches your scenario.

Thanks Joseph,

I did some reading about this error message and knew about the COP file. The issue with COP file installation is that we can NOT switch back to the previous version if the upgrade goes worng. I rather finding a safer way of apporching this issue. Is there any other way to wourk around this error message?

Thanks,

You can clean the common partition by adjusting the log partition low water mark and high water mark settings in RTMT.  The system will delete log files until the low water mark is reached.  Hopefully that will free up enough space to perform the upgrade.

Thanks Joseph,

This sounds like saffer solution. Could you please share with me the procedure of performing the adjustment

Thanks,

I tried to lower the low water mark threshold to10% but nothing changed. Do I need to lower the high water mark as well. Our server has only one disc with 75G. Would the COP file free up enough space to install the upgrade?

Thanks,

MK

Hi MK,

If the percentage of disk usage is above the high water mark that you configured, the system sends an alarm message to syslog, generates a corresponding alert in RTMT Alert Central, and automatically purges log files until the value reaches the low water mark. So, try lowering the high water mark value as well and then restart the Log Partition Monitoring service.
