Proxmox Error: (warning) Incorrect quota shutdown for id xxx recalculating disk usage

I came across this error today when trying to manually backup the container to create an OpenVZ container template.

It occurred, in my case, when trying to start the container VMID 600 after been playing around within it’s root folder from the host’s terminal. The following error was presented:

Starting container ...
vzquota : (warning) Incorrect quota shutdown for id 600, recalculating disk usage
vzquota : (error) quota check : lstat `EelIMf': Input/output error
vzquota on failed [1]
TASK ERROR: command 'vzctl start 600' failed: exit code 60

To fix the issue, we need to turn off the quota for the VMID and then back on again.

vzquota off 600

The output should look like below:

vzquota : (error) Quota is not running for id 600
vzquota : (warning) Repairing quota: it was incorrectly marked as running for id 600

You then need to turn the quota back on, to ensure your container’s disks are restricted to the size you have set for it.

vzquota on 600

You should now be able to successfully start the container, error free!
