Hello Gluster-Community,
we consider to build several gluster-servers and have a question
regarding lvm and glusterfs.
Scenario 1: Snapshots
Of course, taking snapshots is a good capability and we want to use
lvm for that.
Please keep in mind, not just LVM, but LVM's "thin volumes"
Scenaraio 2: Increase gluster volume
We want to increase the gluster volume by adding hdd's and/or by adding
dell powervaults later. We got the recommendation to set up a new
gluster volume
for the powervaults and don't use lvm in that case (lvresize ....) .
What would you suggest and how do you manage both lvm and glusterfs
together?
Thanks in advance.
If you use LVM, it is quite simple just to increase the volume. When you
add new HDDs, create new logical volumes on them, make the file system,
and add it as another brick to your gluster volume (gluster add-brick
volumename replica N ip.add.re.ss:/new-brick ... etc...).
