<div>Hello List!<br>
<br>
</div>
I have a very small test cluster with Lustre-2.10.1 on both client and server.<br>
</div>
I am testing Progressive File Layout and Data on MDT functions.<br>
<br>
</div>
The backing file system on the Lustre targets is ZFS-0.7.6-1 and the OS is CentOS 7.3.1611. The storage was built from source on the cluster itself.<br>
<br>
</div>
PFL functions as described in the lustre_manual.pdf Chapter 19.5.<br>
</div>
In attempting to test Data on MDT (DoM) which uses PFL, my "lfs setstripe" command does not recognize the "-L mdt" flag. It is not included in the "man lfs-setstripe" for my 2.10.1 lustre and trying to use the command example in the lustre_manual.pdf Chapter
20 2.1.1 example:<br>
</div>
> lfs setstripe -E 1M -L mdt -E -1 -S 4M -c -1 /mnt/L210/DoM_test <br>
</div>
fails with "setstripe: invalid option -- 'L' ..." and prints the setstripe help.
<br>
<br>
</div>
Sure enough "man lfs-setstripe" does not show the existence of the -L mdt option described in the manual Chapter 20.
<br>
<br>
</div>
Has DoM landed yet? If yes, in what lustre version?<br>
</div>
If DoM is in lustre-2.10.1, is my syntax faulty?<br>
<br>
</div>
<div>P.S. I am already looking at moving the test system to lustre-2.10.3 because of LU-9529/LU-9530 lfs migrate item.<br>
</div>
<div><br>
</div>
Cheers,<br>
