[ovirt-users] oVirt hosts mounting old storage domain even though it's not listed in the engine

We have an oVirt cluster with multiple hosts that continues to mount an old storage domain we used for ISO images. The engine does not show this old storage domain and I've even looked at the engine sql database and not found this old storage domain. Manually unmounting the ISO storage domain on the hosts doesn't fix it as it will remount within a few minutes. Is there some way to manually make vdsm stop remounting this old path? I didn't know if there is a way to regenerate those files from scratch. We've went through all our VMs and removed the cdroms even trying to get it to stop. We're going to try rebuilding a host from scratch to see if it's an artifact left on the host versus an artifact that's coming from the engine. Any help would be appreciated!
