[pve-devel] pve-storage: add Glusterfs Plugin

[Alexandre DERUMIER]

I really don't known how it's works,
as by nature, glusterfs is done to manage file and not blocks.
So maybe it need to copy the whole file instead missing blocks ?

from doc:

"
What about deletion self/auto healing?
With auto healing only file creation is healed. If a brick is missing because of a disk crash re-creation of files is ok but if it's a temporary network problem synchronizing deletion is mandatory.

I tested with your single 3-node setup. 

But I do not understand how that self-healing work. I simply 
installed a VM, and rebooted one node during install. 

After that there is a high processor use with glusterfs/glusterfsd on 
all nodes. 

But how can I display recovery status? 
Seems they simply copy the whole data to the node that was offline?
