[Gluster-users] Double counting of quota

[Alessandro De Salvo]

Hi,
just to answer to myself, it really seems the temp files from rsync are the culprit, it seems that their size are summed up to the real contents of the directories I’m synchronizing, or in other terms their size is not removed from the used size after they are removed. 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.
Cheers,

	Alessandro
