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,

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. If the gluster bricks are created in root partition then once
the update of the node is done, you will not be able to see any of the
bricks.
Hope this helps !!!
Thanks
kasturi.
