How to create a config for create_lmtconfig

[PDC admin]

I have installed the packages, cerebro and mysql. It seems like I get
some data from the speakers to the listener, but it never seem to
reach the db, since all the ltop,lstat and lwatch fail miserable.
SELECTing from different tables indicate only the MDS related tables
have data input to them. Time to debug from scratch.

It looks like the create_lmtconfig script believes OSS and OST relate
in a way it doesn't in our site.

This is how our site looks like:

MSD/MGS - one host
OSS-3 with three OST
OSS-4 with three OST

It looks like create_lmtconfig thinks OST should be spread long the
OSS. They aren't at our site. This is how it is:

OSS-4
OST0000
OST0001
OST0002
OSS-3
OST0003
OST0004
OST0005

i.e. they are not "striped" out.

How do I write a config file for create_lmtconfig to create SQL that
matches that hierarchy? We don't "skip" OST across the OSS.

Something like:

mds {
name mds1
uuid test-MDT0000
}
ost {
name ost4,ost3
uuid test-OST{HEXINDEX}
skip 1
numdevs 3
}

Incidentally, in the upcoming lmt version 3, this will be unnecessary.
Once you create the database for a particular file system, any servers
reporting in via cerebro will get automatically added.
