Re: [Bacula-users] Bacula stalls after 2.5 TB

Stall is a very frequent verb in NFS world, could be possible that there's 
something with it
(client part, or server part)

At that "stall" time did a df or a ls of the mounted partition give response, 
or is it also "stalled" ?

I'm just guessing ...
