[conspire] The practice of making ext4 a default needs to die an excruciating and gruesome death

Interesting info on filesystems.
I've been experimenting with ZFS on Ubuntu (Precise Pangolin),
using it for two separate five-drive "raidz2" arrays (yep I know,
a lot of wasted redundancy, but the drives are so big nowadays).
It has coped well with the inevitable drive failures: linux seems
somewhat better than solaris at coping with hotplug (using an Asus P8Z77-V
motherboard with a couple of five-drive "icy docks" hooked up to it).
With ZFS the "resilvering" only needs to do the data, not the entire
drive, so it's quicker than software raid raid5 which takes the same
(long) amount of time regardless of how full the filesystem is.
I'm not usre who's maintaining the ZFS kernel drivers on Ubuntu,
but they seem to be doing an OK job of it, most of the stuff works
"as advertised". I haven't tried very many things yet, just the basic
"zpool replace", "zpool scrub", and using rsync to copy stuff over.
Anyone else trying out ZFS?
