Apologies if this is a total noobie question, but I am new to ZFS. My problem is that 1.8 Tb of disk space has mysteriously disappeared from my file server: # df -h | grep home zroot/home 6.0T 6.0T 48G 99% /usr/home/storage zroot/usr/home 4.2T 4.2T 48G 99% /usr/home du -sh /usr/home/* 715M /usr/home/julf 4.2T /usr/home/storage So where did the 1.8T go? Don't think the ZFS overhead is that big. And no, there are no deleted files hanging about. Julf
