I am sorry, but what I hear and see from ZFS on Solaris does not raise the slightest wish to migrate my xfs volumes ;-) Some coworkers run servers with Solaris 9 and 10...
The existence of XFS makes my point. I hope Linux opens up to more good stuff, instead of retreading ext 2-3-4. Linux filesystems brought down a major worldwide e-mail service last month. They were several days (cough) doing a single fsck on a single disk -- which still did not fix the problem.

About XFS and ZFS, http://see.sun.com/Apps/DCS/mcp?q=STI00HTG6Hjxpv
"Antnee (Q): How do you feel that Solaris holds up to the latest release of IRIX? And is it true that ZFS is still inferior to SGIs XFS?
Adam Leventhal (A): Are they still releasing IRIX, and are people still running it? I had no idea. ZFS is far and away superior to XFS."
