Next-gen node (since 4.0) doesn't have any strong notion of "persistence", unlike previous versions of oVirt Node.
My guess would be that /exports was not moved across to the new system. The update process for Node is essentially: * create a new lv * unpack the squashfs in the new RPM and put it on the LV * Go through /var, /etc, and /root to see if any files were modified/added, and copy those to the new layer * Add a new bootloader entry * Re-install any persistent RPMs I would guess that /exports as not on its own partition, so it didn't carry across. Mounting the LV for the old image somewhere (/tmp/...) will make them visible again, On Tue, Dec 19, 2017 at 9:26 AM, Kasturi Narra <[email protected]> wrote: > Hello Matt, > > All the partitions will be persisted when gluster is installed on > the ovirt node since gluster recommends user not to create bricks in root > directory.
