Been using ZFS for a good bit now, and particularly on my laptop. Until B60 is out, I''ve kind of refrained from using ZFS boot. Works fine, but I ran into various issues, plus when it is upgrade time, that is a bit brutal. What I''ve been wanting is a way to make my laptop a bit more "redundant", so to speak, a bit more travel proof. So, I just set aside a slice on the internal hard disk, and added a compact flash memory card in a PC card adapter, and created a mirrored pool out of the two "device". My Documents folder is now automatically mirrored on top of all the other ZFS advantages. It has been pretty solid. I just replicated the steps with an IBM microdrive in a similar laptop and put the steps on my blog: http://solarisdesktop.blogspot.com On a similar vein, I''ve been demoing raidz, raidz2 and hot spare with usb sticks for work and I''ve found some issues which i''ll post later this week to this list.
