Agreed, ZFS rocks.

I started using OpenSolaris fileservers at home in 2007. I went through multiple upgrades since ten: 5x500GB, 7x750GB, and currently 7x1.5TB (all raidz).

I am just about to upgrade to my 4th server with 6x3TB in raidz2, which will be running FreeBSD this time.

Due to the sheer number of drives and continuous 24/7 operation, I experienced 4 drive failures over the years. Everytime ZFS has handled the failure gracefully, and I was able to swap the drive and rebuild the array without a hitch.

I take daily rotating snapshots - incredibly useful when you accidentally stuff.

I also run weekly scrubs, which have allowed me to witness 2 or 3 silent data corruptions which were automatically self-healed by ZFS (CKSUM column in zpool status).

I mostly use the file server to share videos & photos via NFS, and to store encrypted backups of my laptop. It has become so useful and practical that I started to use it as an iSCSI server as well to boot some diskless Windows test machines for GPU projects.

All in all, ZFS deserves all the praise you hear.
