I've tried to copy a directory and it never ended, now I'm unable to do du -sh on that directory either. The process is stuck for several minutes even though the directory is not that big: 95715 root 1 20 0 10540K 2040K zio->i 2 0:02 0.09% du I don't have any tunable regarding ZFS in /boot/loader.conf. The system has 16GB of RAM, I thought it was enough. It runs FreeBSD 11.2 at the moment. Any help would be appreciated because as a server restarting it almost once a week is not an option. Disks are fine as smartctl report every morning. Regards, -- David
