Hi Alexandre, Yeah we are using filestore for the moment with luminous. With regards to client, I tried both jewel and luminous librbd versions against the luminous cluster - similar results.
I am running fio on a physical machine with fio rbd engine. This is a snippet of the fio config for the runs (the complete jobfile adds variations of read/write/block size/iodepth). [global] ioengine=rbd clientname=cinder-volume pool=rbd-bronze invalidate=1 ramp_time=5 runtime=30 time_based direct=1 [write-rbd1-4k-depth1] rbdname=rbd-tester-fio bs=4k iodepth=1 rw=write stonewall [write-rbd2-4k-depth16] rbdname=rbd-tester-fio-2 bs=4k iodepth=16 rw=write stonewall Raf On 20 September 2017 at 16:43, Alexandre DERUMIER <aderum...@odiso.com> wrote: > Hi > > so, you use also filestore on luminous ? > > do you have also upgraded librbd on client ?
