Andy, Thanks, that is helpful. > If you want to leave it open-ended and can't use an LVM, then yes, you > would need two xrootd's. The problem with LVM is that they typically do not allow you to remove disks from volumes. Very Large monolithic filesystems also scare me (zfs not withstanding...) One more question: Can I force xrootd to bind to a particular network interface? I know I can specify the port, but I want to specify 192.168.1.10:1094 (ie, private eth1) rather than 128.91.45.10:1094 (ie, public eth0). Thanks. -paul
