Hello collective wisdom,
fio-3.12 + CEPH 13.2.2 (mimic) here.
So it appears that unlike file based engines such as libaio where --filename allows for multiple block devices to be specified on the same line, --rbdname of RBD engine, doesn't accept multiple rbd images separated by colon (:). If that's indeed the case, is it possible to enable such functionality? If yes, how can I put in a request?
While at this, will the IO be spread evenly among the RBD images, if I specify multiple rbdname like below?
[global]
invalidate=0
ioengine=rbd
clientname=cephuser
clustername=ceph
pool=rbd
rw=randwrite
bs=4k
[rbd_iodepth32]
iodepth=32
rbdname=image0
rbdname=image1
