Separate /usr partition

[Gene Poole]

If possible, I'd like to jump in on this conversation about a separate 
/usr partition.  I work for a large corporation and we run multiple 
platforms (AIX, HP-UX, RHEL, Solaris) and most, if not all, of our servers 
not only have separate partitions, but separate file systems. If you are 
using LVM, the use of separate file systems make for much easier space 
management ( if /usr starts to run out of space, we get alerted and all we 
have to do is extend the /usr logical volume). On RHEL, the default disk 
definition is /boot; / (root); and swap. So we just took it one step 
further and split up  the root directory and file system. And by splitting 
it up, you can put the different file systems on different disk 
allocations (raid-0; raid-1; raid-5; etc.) depending on their uses.  If 
you take the default disk definitions and then add, say, oracle database 
you get oracle mixed in with the OS.  Is this something you really want?

This also allows you to move file systems to SAN devices without an 
outage, under VMware.

Thanks,
Gene Poole
