No! No reboot at all.
The directories were mounted via nfs to all our cluster,
and are of the type 

/pool/user

all directories from 

/pool/g*

to

/pool/z*

have disappeared.

Of course NO COMMAND of the kind rm /pool/[g-z]* was issued.

Not at all.
Here I am.

Can you use my metadata, or is it useless?
Thank you!
