Using the clone and copying data from it is not initially obvious, so I've added a procedure to the wiki for $subject: http://sources.redhat.com/lvm2/wiki/HardwareSnapshotRestore Please take a look and let me know what your think, feel free to modify/update as you feel necessary. regards, Tom -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkg0RlkACgkQOZBvfQY8NVp2EgCfYzUno36yrBlzjzmoD0aD7Gkx SoIAn0Jz1mlrzuV+Q9RiRbwKmdFIquXL =C9NG -----END PGP SIGNATURE-----
