We actually resize volumes often. Some of our storage volumes have 30 LUNs or more. We have so many because we've virtualized most of our infrastructure, and some of the hosts are single-purpose hosts. We don't want to allocate too more storage in advance, simply because it's easier to grow than to shrink. Stop the host, grow the volume, e2fsck/resize2fs, start up and go. Much nicer than increasing disk capacity on physical hosts. CLVM works well for this, but that's about all it's good for IMHO. I prefer to use the SAN's native volume management over CLVM when available. Haven't tried DRBD yet but I'm really tempted... it sounds like it has come a long way since its modest beginnings. -Jeff -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
