The manual is a good reference and something that I have already looked at, thank you.

The question that it does not answer is 'what is the best configuration of disks for performance'; should "/" have it's own disk? Or "/var". How many disks should I put into a logical volume to get the best performance payoff per disk? I am not really limited by resources here so I am looking at the best performance regardless of the number of disks involved.

Getting the logical volumes configured should not be a problem but my next question is 'how do I migrate the data from the old disk to the new'? I didn't spot that in the manual ... perhaps I missed it?

Thanks.

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems
