<p>Hi,</p>
<p>The output indicates stripe count of 1. Use lfs setstripe to set the stripe count to something other than 1. I.e. -c -1 for all osts.</p>

Hello!<br>
<br>
I just migrate my lustre filesystem to version 2.2. I am trying to
activate the stripe, but when I copy a file into the filesystem,
it's allocated into only one OST.<br>
<br>
This is my procedure:<br>
<br>
<small><i>From client: <br>
</i></small><small><i>#> </i></small><small><i>lfs setstripe
-s 1M /mnt/data/<br>
</i></small><small><i>#> </i></small><small><i>lfs df<br>
