Sorry, but there is no 'parallel' activation from lvm2 command - as lvm2 is not
multithreadded app (and is quite far away from that).
Just had a weird thought. What would happen if I ran the "vgchange -ay"
command, and then a few seconds later ran a bunch of "lvchange -ay" commands
in parallel?
Since all of them are 'activation' requests - you just end with success
and everything should be activated.
Much more interesting case is - if you run in parallel activation
and deactivation :) - then the result depends on last executed command.
Would that maybe let me activate non-snapshotted volumes even if the
snapshotted volumes took a long time?
Yes - you could activate things in parallel this way - since every command has
separate udev cookie - so it waits on its set of LVs.
