The FreeBSD Foundation rounded up a story from Glen Barber, discussing the ZFS filesystem.

This month’s story comes to us from Glen Barber, UNIX Systems Administrator.

The ZFS filesystem is regarded for its robustness and extensive feature set.

Its robustness can be haunting, however, if a mistake is made.  I learned this the hard way through a seemingly innocent typo, a mistake I certainly will not soon repeat.

We use ZFS almost exclusively in the FreeBSD cluster.  I say “almost” because there is one remaining machine that does not use ZFS, because the machine is too underpowered to handle it.

All machines are installed in a netboot environment while logged in at the serial console, providing the utilities necessary for extremely customizable installations.  Most of the installations I have performed on machines in the FreeBSD.org cluster have been pseudo-scripted, with subtle differences depending on the machine, such as if the disks are da(4) or ada(4), the number of disks, how much space to allocate for swap, the number of ZFS pools, and so on.
