One of the main advantages of having a SAN is being able to add space to a volume (LUN) Currently when we expand a volume on the san, we have to unmount the filesystem, rescan the LUNs, then run fdisk on that volume, delete the partition entry, and recreate it to use all the space.. then at that point we can run ext2online / gfs_grow to resize the filesystem. I would be VERY nice if pvresize / pvextend existed, that way one could expand the volume on the SAN, rescan LUNs on each cluster member, run pvresize / pvextend, run lvextend and then gfs_grow and call it a day. I mentioned this at the RedHat summit, and got a few puzzled looks, but never got an answer on the matter. > Oh certainly... > > I was just trying to think of why someone would want to use GFS to do > this, and the idea of the machines not have pre-fixed partition sizes was > about the only thing I could think of. > > -- > > Linux-cluster@xxxxxxxxxx > http://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
