I've been using LVM2 under Ubuntu Breezy for several months now; the original partitioning & volume groups were created by its installer. I've just decided to add a second disk, and I'm having problems with what should have been the simplest step, namely pvcreate. My new disk is /dev/hdd. But doing "pvcreate /dev/hdd" complains "Device /dev/hdd not found." The disk is surely online: I can do, e.g., "strings /dev/hdd | head -1" and get "LILO" because this disk was originally a random non-LVM'ed disk from another machine. I would have -expected- pvcreate to complain about a partition table existing (at which point I would have zeroed it and tried again), but not to complain that the entire disk doesn't exist. What's the problem here? I'd rather not have to repartition the (several) partions on the device into one, and then use just that single partition, when I logically wanted the entire disk to just be part of my VG. (Though if that's the only way to get pvcreate to behave, I can do so.) But the howto at tldp.org very clearly states that this should just work (it uses /dev/hdb as its example; but that shouldn't matter :), and the manpage for pvcreate both talks about whole disks, and includes whole disks in its example at the end. So what should I do? Thanks! P.S. pvcreate --version claims LVM version 2.01.04 (2005-02-09), library version 1.01.03 (2005-06-13), and driver version 4.4.0. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
