Note : After the execution of lvextend with non-strict allocation policy set, cross mirror
appears.
2.The order of the physical volumes in /etc/lvmpvg is also important. The first device
which stays in /etc/lvmpvg is possible to be used as first device to write to after
execution of lvextend.
Note: This is only tested behaviour, but it could also depend on the particular
configuration.
