[Gluster-users] How fill my volume for test?

[Nag Pavan Chilakam]

IMO, I kind of agree that there isn't a standard way to fill a file system(every vendor tries their own variant like chunk size,etc)?
Also, Don't take the IO methods for validation of perf tests based on the methods I mentioned, as I don't have comprehensive idea of perf testing.
If you are behind a certain usecase for your perf test, Kindly ellaborate the intent in details. Hopefully someone on this list with that knowledge can help you.

Thank you
Is it correct that there is not a standard way to fill a file system?
If I fill my gluster volume with each of these methods, the result of
performance test (speed of read, write, ...) are valid?
