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

Transactional updates will go into LVM after mid November.  Checksums
for the metadata will also go in at this point.  ATM problems are
spotted by consistency checks (the is a lot of duplication between the
pv's).  If a problem is spotted the administrator can restore from the
automatic metadata backups.
