Subject: should I use btrfs on Centos 7 for a new production server?

I have a well tested and working fine Centos5-Xen system. Accumulated
cruft from various development efforts make it desirable to redo the
install. Currently a RAID-10 ext4 filesystem with LVM and 750G of
storage. There's a hot spare 750 drive in the system.
I'm thinking of migrating the web sites (almost the only use of the
server) to a spare then installing Centos-7 and btrfs, then migrating
the sites back.
I see RH marks btrfs in C7 as a technology preview but don't
understand what that implies for future support and a suitably stable
basis for storage.
Technology preview means no full official Red Hat support, just preview
for technology.

It may comes to full support in later version if it matures.
The demand on the system is low and not likely to change in the near
future, storage access speeds are not likely to be dealbreakers and it
would be nice to not need to use LVM, btrfs seems to have a better
feature set and more intuitive command set. But I'm uncertain about
stability. Anyone have an opinion?
If I am sysadmin, I will still prefer the mature linux soft raid/LVM.
Less bug, mature kernel/user-land tools and use case,and you don't need
to always update kernel/btrfs-progs
to address known bugs or fix corrupted fs
(if stay away from
scrub/replace/balance/almost-full-disk/sudden-power-failure, it will
shouldn't happen though)
But, if you want to contribute to btrfs, such production environment may
expose some problem we didn't find.
Although you may take a lot time compiling latest kernel/btrfs-progs and
doing btrfs-image dump, not to mention
the offline time...
Thanks,
Qu
Dave
