[linux-lvm] LVM metsdata

[Lee Go-Tze]

I have a novice question.  How does the LVM 
protect its metadata.  I mean does it do some 
sort of metadata check when machine comes up 
(notices the system did not shutdown properly)?
Or maybe it uses journaling? I imagine the 
updates to lv/vg/pv structures have to be 
transactional.

Thanks,

Go-Tze
