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. 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. Felix

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...). -- Kind regards, Boris Zhmurov mailto: bb at kernelpanic.ru
