How would a distributed fio work against a single block? Who'll coordinate the writes and reads?
from benchmark-operator.
This issue came up when I was evaluating LVMO Block performance on SNO (by specifying VolumeMode = block in PVC). The FIO tests wouldn't run because of issue described above
It again came up when I had to measure LSO performance where block PVs are created.
My plan is to assign one PV (from 1 NVMe) to a single FIO server and measure performance. This way the storage wouldn't have the shared access.

@mykaul - Ripsaw never shares the same PVC between Pods. Ripsaw creates as many Pods as we define in the servers
variable (in the benchmark CR). Each Pod gets its own PVC. We can tune the amount of parallel IO per PVC with the numjobs
and iodepth
variables.
Because of this, block PVCs should work just fine

@shekharberry I think you just need to fix this here:
https://github.com/cloud-bulldozer/benchmark-operator/blob/master/roles/fio_distributed/templates/servers.yaml#L51
Add another if clause for block mode. (could you send a PR please?)
As far as I can see, fio on VMs should work fine already and is not affected by this bug
from benchmark-operator.
Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
