Emcopy - unable to get volume size info

Hi to all,

i have to migrate customer file server to new unity xt file server, but when I launch the command to the first copy, I have this error "emcopy unable to get volume size info".

it isn't the first time that I used emcopy, but it's the first time that I see this error

I have checked that the user that launch the command has the right privileges yet, but I d0n't know how I can try now.

Can you help me, please?

Thanks in advance
