Something is eating away free space on our Datadomain and I can't figure out what. Its decreasing about 40GB in hour. With two days (48 hour) there was 2TB gone. There were some old data which I cold delete and after filesys cleaning cycle there was 11.60TB free space again but it started to go down again. I looked that there is debug/tcp log in Datadomain an I see servers which connect to Datadomain there. But can I read out from there how much data moves between servers and DD? There are info like "send 23.4Mbps" in some rows. Or how do I interpret info in tcp.log? Or how can I hunt down the space eater? I don't seem to notice any big growth in mtree sizes either.
