[gpfsug-discuss] NSD access routes

[Oesterlin, Robert]

Hi Dave

I’ve done a large-scale (600 node) LROC deployment here - feel free to reach out if you have questions.

mmdiag --lroc is about all there is but it does give you a pretty good idea how the cache is performing but you can’t tell which files are cached. Also, watch out that the LROC cached will steal pagepool memory (1% of the LROC cache size)

I'm testing out the LROC idea. All seems to be working well, but, is there anyway to monitor what's cached? How full it might be? The performance etc??

I can see some stats in mmfsadm dump lroc but that's about it.
