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. ----- Original Message ----- From: "Tahereh Fattahi" <t28.fattahi@xxxxxxxxx> To: "Nag Pavan Chilakam" <nchilaka@xxxxxxxxxx> Cc: gluster-users@xxxxxxxxxxx Sent: Wednesday, 31 May, 2017 10:06:11 AM Subject: Re: How fill my volume for test? 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?
