I'm running a single pool consisting of around 16 x 2TB drives, and with the data they hold - with pool duplication - the total size is 21TB. Every few days, a sizeable chunk (2-3 TB) of that data drops out of duplication and so Drivepool dutifully goes to work re-duplicating it. All is good again, but then it happens again in a few days. I try to keep up to date with the latest beta releases, but I just wondered if this is a known issue?
