An example of the way I see it working is like this:
Say you have a Volume Group VG1 across two PVs, PV1 and PV2, containing Logical
Volume LV1 containing the root filesystem.
You have a trigger rule saying "When you see the whole of VG1, activate LV1
inside it" and another saying "When you see the filesystem with UUID X, mount
it." (Default rules can be generic of course, like 'activate any VG when you
see it' and 'activate any LV when you see it' and 'mount any filesystem
when
you see it'.)
Nice.
You still need a timeout to avoid waiting for ever for the root filesystem
to appear when one of the PV has been disconnected from the system.
But this "lost hope" timeout is a lot better than the current "wait in any
case"
one.
