Wojciech hates it for some reason, but I wouldn't let that deter you. 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
