I've had that problem too. Two workarounds. Here's what I usually do: 1a) Map the snapshot LUN to a *different* host than the production machine. 1b) Change the UUID and VG/LV there. 1c) *Then* map the LUN to the production machine. Alternatively (untested): 2a) service haldaemon stop; service multipathd stop; service lvm2-monitor stop (not sure which of these is really necessary) 2b) Map the snapshot to the production server in the SAN. 2c) Manually add with echo '- - -' > /sys/class/scsi_host/hostN/scan 2d) Change UUID and VG/LV. 2e) Manually remove with echo 1 > /sys/block/sdX/device/delete 2f) service haldaemon start; service multipathd start; service lvm2-monitor start -- Rich Graves http://claimid.com/rcgraves Carleton.edu Sr UNIX and Security Admin CMC135: 507-222-7079 Cell: 952-292-6529 _______________________________________________ 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/
