I find this all very interesting...
"Please keep in mind the current 0.5.2 stable release does not yet
support a mountable filesystem. This functionality is currently
available only in the 0.6.0-rc6 release candidate."
"Uploaded October 14, 2011"
So in the past ~two weeks, you converted your 15K+ user production
server to ZFS on Linux, as an experiment, and have now decided to change
to another filesystem solution, a mere two weeks later? Or am I
misinterpreting the date given that 0.6.0-rc6 was released?
