Ok, googling reveals lots of conflicting opinions about using LVM in a
VM environment.
I was wanting to use it mainly for its snapshot ability (to get
consistent backups of my mailstore and mysql DBs).
Also it would be very nice to be able to resize things if needed (I have
adequate storage available).
But I've found lots of opinions that using LVM in a virtualized
environment can lead to data corruption, and if this is true, I'd rather
not risk it...
So, LVM or not?
You can make snapshots from ESXi (btw snapshot is *not* backup),
and you can resize VM-disks as well. So the right question is:
What are the LVM features I need? If I do not need any, then why
should I bother with it?
Yes I can't take snapshots with ESXi, but everything I've read says that
for these to be consistent, they need to be done when the VM is shutdown.
Also, they take a LONG time, whereas an LVM snapshot happens almost
immediately.
