[ovirt-users] Partition Trouble on oVirt Node

[Andy Michielsen]

Hello Matt,

Can you perform the command cat /etc/fstab and see what partitions you already created during installation ?

Did you leave the installation to decide what to do with partitioning by itself or did you did that yourself ?

Kind regards.
