I'm using ZFS on several production machines now and it's been beautifully solid the whole time. It has several huge advantages over UFS: - Filesystem sizes are dynamic. They all grow and shrink inside the same pool, so you don't have to worry about making one too large or too small. - You can sort of think of a ZFS filesystem as a directory with a set of configurable, inheritable attributes. Set your /usr/ports to use compression, and tell /home to keep two copies of everything for safety's sake. - Snapshots aren't painful. It's been 100% reliable on every amd64 machine I've put it on (but avoid it on x86!). 7-STABLE hasn't required any tuning since February or so. UFS and gstripe/gmirror/graid* are good, but ZFS has spoiled me and I won't be going back. -- Kirk Strauser
