Hi all,
I've got an extended setup whith two Systems, each with two FC cards.
Every card is connected to a seperate disk array (so one system accesses
two arrays). The other node has access to the same two arrays (standby).
The active server mirrors the data (4 LUNs) between the two arrays via
md. On top is a LVM physical volume. The other system is meant to be
booted but not acessing the VGs.
My question is, if it is possible to let both systems set up the md
mirror without corrupting the data? Is there any data written even when
the VGs are not taken active? I think I remember that LVM refuses to
activate volumegroups which are active on another system, right?
This would save me from caring about IO fencing.
thanks for your help in advance..
