Hi,
We are looking to use ZFS for our OSD backend, but I have some questions.
My main question is: Does Ceph already supports the writeparallel mode
for ZFS ? (as described here:
http://www.sebastien-han.fr/blog/2013/12/02/ceph-performance-interesting-things-going-on/)
I've found this, but I suppose it is outdated:
https://wiki.ceph.com/Planning/Blueprints/Emperor/osd%3A_ceph_on_zfs
Should Ceph be build with ZFS support? I found a --with-zfslib option
somewhere, but can someone verify this, or better has instructions for
it?:-)
What parameters should be tuned to use this?
I found these :
filestore zfs_snap = 1
journal_aio = 0
journal_dio = 0
Are there other things we need for it?
Many thanks!!
Kenneth
