Can someone explain the UUID, etc on a volume and on VGs? Is the UUID stored on the volume, or on the host machine? The reason I ask, is that I have a parrallel scsi raid, which is connected to 2 machines. If i reboot both machines, or go through a vgexport/import procedure (while online), i can see the VGs and LVs on both machines.. can even mount the volumes simultaneously (It was only a test.. I understand that it is not a Shared Filesystem, and would never do simultaneous mounts on production filesystems). This is what I believe to be the case: 1. The UUID is stored on the volume itself, and the VG data is stored somewhere on the disks also. 2. The import/export/activated/deactivated status of a volume is held on the host machine. this allows 2 machines to see the same VG/LVs. Is this correct? And is it supported as a function of LVM, or am I in 'unsupported' territory? -- Matt Schillinger mschilli@vss.fsi.com _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
