Hello, I've asked this before and now am getting ready to build and deploy my first production CEPH cluster.
Is filestore_xattr_use_omap = true required (for an ext4 formatted OSD obviously) if the only usage of that cluster will be RBD? I assume that having this off will improve performance, right? The rationale for me wanting to at least test with ext4 is that on the actual backing storage (11 disk RAID6 on Areca 1882) with fio (using the iometer simulation) on Debian Jessie I get: XFS: read : io=3273.8MB, bw=1737.9KB/s, iops=284, runt=1929861msec write: io=841998KB, bw=446771B/s, iops=71, runt=1929861msec EXT4: read : io=3273.8MB, bw=3878.9KB/s, iops=635, runt=864262msec write: io=841998KB, bw=997621B/s, iops=159, runt=864262msec Regards, Christian -- Christian Balzer Network/Systems Engineer ch...@gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/ _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
