We do not use LVM for root and boot.
a) We use LVM for /home, /usr, /var, /opt, /tmp, /local. The root and boot
for us are mostly static. They do not grow much. Growth is the main reason
why we use LVM.
b) Root and boot are critical enough not to be in a vg.
Here is one reason why it is not good to use LVM for root and boot.
I added a volume to a vg but forgot to do mkinitrd and zipl to bake it into
the ramdisk. Next IPL, the vg would not come up due to inactive disk.
Thanks to the folks here I used the chccwdev to activate it. If root and
boot were in the LVM, nothing would have come up. Even fixing it from
another guest would be complex.

Is anyone using lvm for all there file systems safely. We currently
only use lvm for non-system file systems only, but have a test box
that uses lvm for every file system except /boot.
The test box is working fine but i just wanted to check to see if
there is any reason to not use lvm for system file systems (/usr,
/var, /ect...) before i made a production box all lvm.
Also the same question about reiserfs? Does anyone use reiserfs? Is
there any reason not to use reiserfs?
