[Lustre-discuss] Lustre Storage Sizing- How?

Hi
I am considering a new storage of 30 TB usable space with a 2 GB/s sustained
read write performance in clustered mode. But not able to figure out sizing
part of it like what OSS, what OST and what MDS.
Urgent help would be highly appreciable 

Thanks and Regards
Deval

Actually lmt is not web-based.  Tools for viewing lustre performance
are included: "ltop" is curses based, and "lwatch" is X based.

Hello,

Replying to my own subject line,   I had to reboot the
Lustre-1.6.7.1smp client for reasons completely unrelated to Lustre
(very related to NFS).  After the reboot, the error messages regarding
the handle change went away.   The Lustre disk mounted correctly and
is usable after the client reboot.

Just FYI,
megan

I have it running on 1.8. 1.1. It works well. I had to edit the SQL it
generated though.
