Hi List,
i am using Ceph Infernalis and Ubuntu 14.04 Kernel 3.13.
18 Data Server / 3 MON / 3 RBD Clients
I want to use RBD on the Client with image format 2 and Striping.
Is it supported?
I want to create rbd with:
rbd create testrbd -s 2T --image-format=2 --image-feature=striping
--image-feature=exclusive-lock --stripe-unit 65536B --stripe-count 8
Do i become better single Thread performance with a higher stripe count?
If not: Should i use Ubuntu 16.04 with Kernel 4.4 ? Is it with that
Kernel supported?
The manpage says:
http://manpages.ubuntu.com/manpages/wily/man8/rbd.8.html
*PARAMETERS*
*--image-format* *format*
Specifies which object layout to use. The default is 1.
ยท format 2 - Use the second rbd format, which is supported by
*librbd and kernel since version 3.11 (except for striping).*
This adds support for cloning and is more easily extensible to
allow more features in the future.
Regards
