Hi Guys,
I'm using the librbd engine and trying to determine what exactly happens
when multiple --name parameters are passed. Primarily, I'm wondering if
each fio process ends up writing to the same blocks on the rbd volume
during sequential writes. Looking at the code, I see a note that we
pretend to deal with files even if the engine doesn't understand the
concept of files:
https://github.com/axboe/fio/blob/master/engines/rbd.c#L405
https://github.com/axboe/fio/blob/master/filesetup.c#L1239
I'm not seeing anything (might be missing it) in the rbd engine or there
that would partition the volume based on the process though. Am I
missing anything?
Thanks,
Mark
