Ext4 hacker Ted Ts'o converts his laptop

Using zfs here, a good 30-40 TB of space, in regular use, so far so good. We are only using
concat, not raid Z, we have proper raid hardware underneath. The import/export ability is very
nice, I really couldn't believe it worked when i tried it (hot swapped two disks between two
machines), it was a pleasure to rip up my contingency plans! Quota and reservation handling is
great, it really does simplify things for our users, it's just a shame it cant be used as a
cluster filesystem! (me, demanding? never!).
