[Gluster-users] lvm layout for gluster -- using multiple physical volumes

Hi all,

I want to use lvm for two reasons:

- gluster snaphosts
- ability to dynamically add space to a brick.

Here's what i'd like to do:

1. create two more physical volumes
2. create a single volume group from those physical volumes
3. create a single logical volume
4. make the single logical volume a brick

So my questions are this:

1. is there any issue with adding and remove LVM physical volumes from the
logical volume group that backs the gluster brick?
2. is there any issue with having multiple physical volumes in the LVM
volume group?
3. will disk size increase more  with gluster because LVM is being used
instead a filesystem like XFS?
