I do use as well XFS and can't reproduce any issues with it when using anything >= GlusterFS 2.0.4. Older 2.0.x releases of GlusterFS where ultra unstable for me but starting from 2.0.4 things seem to get better. Currently I am using 2.1.0git in production for serving web pages and things work flawless. If it continues like that then I am going to try again to move my mailstorage to be on GlusterFS. But not in the next 2 to 3 weeks.

Anyway... GlusterFS and XFS = no hangs at all for me.
Crashing GlusterFS? Yes! Hangs? No!

If you use XFS then be sure to not use a Kernel from the 2.6.29 and 2.6.30 series as it has an bug with XFS. There are patchs for 2.6.29 and 2.6.30 but none of them is included in the main line of the Kernel. Maybe released 2.6.31 Kernel will fix the issue? RC8 however has still the same issue as 2.6.29/2.6.30.
