new oss servers added - how do I get lwatch to see them?

[lisa]

Hi all,
I added two new oss servers each hosting several ost's to my lustre
file system which I monitor
with lmt.
cerebro-stat sees them but the lmt tools do not. How to do I get
lwatch to see them?

Lisa,

In lmt2.x you would need to add them to the database.
It might actually be easier for you to upgrade to lmt3.
lmt3 adds lustre servers to the database on the fly when
they report in via cerebro.

Thanks for the quick response jim.
I will probably go the lmt3 update route.

Another question. If I do decide to upgrade to lmt3 is there an
upgrade path (ie will config files be saved etc)? or is this like a
new install.

Have a look here:

http://code.google.com/p/lmt/wiki/LMT3announce

http://code.google.com/p/lmt/wiki/Installation

Basically the lmtrc files on the server where mysql runs are
replaced with one config file /etc/lmt/lmt.conf in a new format.
You would probably set up that file, then upgrade the lmt-server package,
then the lmt-server-agent package on the the lustre servers.

The gui is now in a separate package lmt-gui. It still uses the old lmtrc
file but requires it to be in your home directory.

Please open lmt issues for any glitches you encounter in the documentation
or the code.

Thanks,

Jim
