Eventually I need to start working on a gfs2_shrink tool for gfs2, but I don't think GFS will ever be able to shrink. As for growing, it sounds like you're already familiar with that. You just do something like: lvresize or lvextend the logical volume mount the gfs volume to a mount point gfs_grow /your/mount/point It's probably safest to do gfs_grow when there is not a lot of system activity. For example, at night when the system is not being beat up by lots of I/O. <div><div></div><div> Regards, Bob Peterson Red Hat Clustering & GFS -- Linux-cluster mailing list <a href="mailto:Linux-cluster@redhat.com" target="_blank">Linux-cluster@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/linux-cluster" target="_blank">https://www.redhat.com/mailman/listinfo/linux-cluster</a> </div></div></blockquote></div> </div></div>-- Alan A. </div> </blockquote></div> -- Alan A. </div>
