[lustre-discuss] OST Lustre Write Time

[Jack Marquez]

Hi,
I am really new at this.
I want to ask you if you can help me with this:
I have configured a Lustre server of 67 nodes. 1 client, 1 MGS, 1 MDT, and
64 OST. I am writing one file of 64GB from the client with the command dd
and I have put a stripe of 1GB.

How can I measure the write time that takes each OST to store 1GB?

At this moment I am measuring the time that takes write the file with the
'time' command.

Thank you for your help!!
