My understanding is that when you ask an OSD to bench (via the admin socket), only that OSD executes, there is no replication. Replication is a function of PGs. Thus, this is a narrowly-focused tool with both unique advantages and disadvantages. > On Dec 26, 2022, at 12:47 PM, hosseinz8050@xxxxxxxxx wrote: > > Hi experts,I want to know, when I execute ceph tell osd.x bench command, is replica 3 considered in the bench or not? I mean, for example in case of replica 3, when I executing tell bench command, replica 1 of bench data write to osd.x, replica 2 write to osd.y and replica 3 write to osd.z? If this is true, it means that I can not get benchmark of only one of my OSD in the cluster because the IOPS and throughput of 2 other for example slow OSDs will affect the result of tell bench command for my target OSD.Is that true? > Thanks in advance. > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
