[CentOS] ZFS on Linux

I am planning to use ZFS on my Centos 5.2 systems. The data I am
storing is very large text files where each file can range from 10M to
20G. I am very interested on the compression feature of ZFS, and it
seems no other native Linux FS supports it.

My question are: Is ZFS stable? How does it scale for very large
filesytems, ie, 2TB to 9TB? How is the performance of fuse? I plan to
use it on my archive server first, so data reliability is very
important

Any thoughts or ideas?

TIA
