Cisco Unity 12.5 - Callers are unable to leave VM's due to space.

[Mogwai]

We seem to be running into an issue where the VM store is full for Unity. The first thing I'm looking to confirm is simply where the VM's are actually stored? I see that we have a mailbox store that is 1.29GB for 765 mailboxes, but looking to see how much of that space is actually used?

When I check the CLI & run a 'show status' I see the disks: Active 76%, Inactive 68%, and Logging 82%. None seem to correlate to the VM store?  Is the VM store a partition on one of these drives?

Is it one user, or all users? If it is the former, it could be a per user mailbox quota.

Sorry for the delay in getting back, this is affecting all users.

You can view the mailstore as configured in your CUC system using the menu  Message Storage > Mailbox Stores and you can view the current Mailbox Quota settings (which can be overridden on an individual mailbox) at Message Storage > Mailbox Quotas > Mailbox Quotas

(Leaving the above as breadcrumbs for folks who find this later....)

A Mailstore size of 1.29GB fairly small and won't run up against any system maximums even if you are on a small OVA or running an SMB version of CUC. So I agree with @Elliot Dierksen that if you are running into this for a specific user you are probably looking at a quota issue. If it is everyone, you have a more significant problem, which we can get into if that is the case.

Hello Maren & thanks for the help, this is affecting all users, and the 1.29GB size being too small is what I was afraid of. I've already adjusted the user that is the most impacted by the issue, but I've still personally run into the issue. 

Would there be any options to free space on that 1.29GB, or possible being able to copy that 1.29GB to another larger drive?

First, the VM Store is a database (one of three) on the CUC server. That db resides on the Active partition, so there should be plenty of room. That said, it is possible that the thresholds have been exceeded. 

Navigate to System Settings > Advanced > Disk Capacity and look at the threshold. The default for this setting is 95%. Is that what yours reads?

If you look at your Mailbox Store (Message Storage > Message Stores) is what shows there the same as what you are seeing via the CLI?

When you say "I've already adjusted the user that is the most impacted by the issue, but I've still personally run into the issue.", do you mean that you have adjusted the Quota for that user? If not, what setting are you adjusting? (Which could lead us to what is going on overall.)
