The pithy ruminations from Klaus Steinberger on 
<[Linux-cluster] Re: Why GFS is so slow? What it is waiting for?> were:

=> There is some more tuning, which could be done unfortunately just on creati
=> on
=> of filesystem. The default number of Resource Groups is ways too large for
=> nowadays TByte Filesystems.

I would appreciate it greatly if you could expand on this.

I'm setting up a cluster that will have several filesystems in the 3~6TB range.
This will be GFS1 over LVM2, with SAN (no iSCSI) connections to the servers, if
that has any bearing on the tuning suggestions.
