Hi Brian,

If I’m not mistaken, once you run the mmlsdisk command on one client any other client running it will produce the exact same output.  Therefore, what we do is run it once, output that to a file, and propagate that file to any node that needs it.

HTHAL…

All,

Does the mmlsdisk command generate a lot of admin traffic or take up a lot of GPFS resources?

In our case, we have it in some of our monitoring routines that run on all nodes.  It is kind of nice info to have, but I am wondering if hitting the filesystem with a bunch of mmlsdisk commands is bad for performance.


Thanks,
Brian
