Hello,
What is your performance or just general requirement?
Because, as you might know, reliability, performance and any kind of things are trade-off.

hi jan,
The answer to this, as well as life, universe and everything, is simple:is it really the case for ceph? i briefly looked in the filestore code a while ago, since zfs is COW, i expected not to have a journal with ZFS, but i couldn't find anything that suggested this was supported (no journal on ZFS that is). (see mail 2014/10/29 on this list form my colleague kenneth)
ZFS.
how do you use it? and relevant configs you can share?

I would say probably not. btrfs (or, "worse FS" as we call it around my office) still does weird stuff from time to time, especially in low-memory conditions. This is based on testing we did on Ubuntu 14.04, running kernel 3.16.something.
I long for the day that btrfs realizes it's promise, but I do not think that day is here.

Howdy,
The Ceph docs still say btrfs is 'experimental' in one section, but
say it's the long term ideal for ceph in the later section. Is this
still accurate with Hammer? Is it mature enough on centos 7.1 for
production use?
(kernel is 3.10.0-229.7.2.el7.x86_64 )
thanks-
