Since the general recommendation seems to be to use iSCSI over NFS wth ovirt, I expect that I am missing something very obvious.
Question: How do I complete the iSCSI storage domain configuration? Hardware configuration: - cluster controller - physical system - compute nodes - 2 - Current file store: NFS on TrueNAS - To-be file store: iSCSI on TrueNAS Problem reproduction: 1. We decided that the problems with NFS (regularly blocking and causing VM's to go into paused instead of IOWait mode) outweighed the benefit of ease of management, so we are preparing to move to iSCSI back end on TrueNAS. 2. We created an iSCSI share on the to-be TrueNAS system and granted access to a "ovirtuser" and group "1", with 30+ TB available storage. 3. We started to add the iscsi share to the ovirt data center using the GUI, under "Storage > Storage Domains" click the "New Domain" button. *Problem 1: *Ovirt immediately found the iSCSI share (yay), but says it has 0 GB and will not allow us to add it to the data center, or edit or remove it, so it is in a limbo state. *Problem 2: *Ovirt shows it on the wrong network (miscommunication). It is finding it on the general network instead of the isolated data network. The TrueNAS will be removed from the general network as soon as configuration is complete. Thank you *David Johnson*
