Re: [ovirt-users] Using both shared and local storage

This might work for you. Of cause it will not be possible to migrate such a VM and the hook will fails an attempt to do migration. Please note that there is a patch https://gerrit.ovirt.org/#/c/42573/ without which it may not work. This patch was merged, but most like is not yet at the ovirt version you use. Let me know if you have other questions with regards to that hook usage. I may also share my unit files for systemd to format and mount the local storage provided by the hook. Anton.
