LVM stuff

note to self

Came across some useful information on storage migrations with lvm, when searching around. Tested again and seems to be working fine on RHEL6, need to make sure same goes for RHEL4 somehow.

ethX adapter names getting incremented in Ubuntu on VMware

note to self

Came across this issue with a P2Vd Ubuntu system. Network interface name seemed to get incremented eth0 >eth1 >eth2 and so on, each time a new adapter is added even when the old one is removed.

It is caused by the udev rule to persist device names with the hardware id located in  /etc/udev/rules.d/70-persistent-net.rules

This blog here helped to figure it out.
