RE: [linux-lvm] lvm and reducing vols/ext3



Not really.  Root file systems tend to be _very_ static in terms of
size.  Other file systems are not like that at all.  Being able to
adjust file system sizes "on the fly," so to speak, is a tremendous
help.  Typically, when my team builds systems, we don't allocate all of
the internal storage up front.  We use what we think is needed, and
leave the rest as part of the LVM "pool."  As file systems grow, we can
add to them without a whole lot of effort.  Using fixed partitions to do
the same thing is a lot more painful.

Mark,

OK, but doesn't the same argument apply to non-root file systems? -  
don't I still have to resize the file system as well as resizing the LV?

I can see that LVs might be quite convenient spread over multiple  
physical drives but I can't see that much advantage on one drive . .

Thanks,

Phil.
