[one-users] OpenNebula KVM / LVM / CentOS "journal I/O commit error"

[Jaime Melis]

Hello Yves,

I finally got around testing this and it does work for me, i.e. the SIZE
attribute is *not* ignored. I've created a section in the documentation in
order to better explain this:
http://opennebula.org/documentation:rel3.6:lvm_ds#snapshot_size

cheers,
Jaime
