[Vijaikumar M]

Hi Alessandro,

Please provide the test-case, so that we can try to re-create this 
problem in-house?

Thanks,
Vijay

I suppose this is someway connected to the error on removexattr I’m seeing. The temporary solution I’ve found is to use rsync with the option to write the temp files to /tmp, but it would be very interesting to understand why this is happening.
