[cisco-voip] Low space on partitions in CUCM

[Matthew Huff]

Evidently this is a known bug:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt97709

The “solution” is to do the upgrade, then do an export and a full redeployment with a new OVA template.

Since there are trust, certs, etc…involved in this, it is a very involved procedure. Ughhh…

I've had these alerts pop up on fresh install during a PCD migration (new VM's) (it was 12.5 from memory)
I spent a bit of time back and forth with TAC and checking with other TAC engineers etc.
I think the outcome was basically that it was the standard setup of the Active Partition, and it isn't really an issue, except that you will get those alerts (and you can adjust the thresholds)

But it's only a partition inside, and basically you have other space available.

What does your show diskusage look like?

I deleted the old firmware files and we don’t use any MOH sources other than the built in one. The copp file is for cleaning up the common partition, but I ran it anyway. The active parttion still shows 98% used. I’m afraid TAC is correct, the older ova file that we used for 11.5 created too small of an active partition for 14, and the only solution is to do a complete rebuild.

Oh right...

1. Delete old firmware files.
2. Delete unused MOH sources.
3. Use the free space .cop file.

The alert that is being triggered isn’t the LogPartition space, it’s the active partition space, which I believe is a separate area. Any suggestion on how to cleanup space on the active parttion?

Hi Matthew,

I totally agree but I think you'll be OK. I've done it when at a similar level and it's helped.

Another thing you might do is to download all the log files and set them to delete when you download them. That might get you at a safer level.

Kind Regards,

James

If it was like 92%, fixing the log threshold would make me feel less nervous. At 98%, I’m more concerned. Maybe I shouldn’t be?

Hi Matthew,

Have you tried adjusting the log file thresholds in RTMT? See https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200581-Procedure-to-Adjust-WaterMark-in-RTMT-of.html for more details.

Thanks,

James

After upgrading from 11.5 to 14, I’m at 98% on publisher/subscriber on the active partition. Cisco TACs only suggestion is to redeploy from scratch from 14 ova. Given the issues with certs, trusts, licensing, etc, I’m loathe to do that. Anyone have any suggestions?
