The exact sequence of commands was: lvconvert --type raid1 -m 1 faldara/utopic /dev/sdb1 lvconvert --splitmirrors 1 --trackchanges faldara/utopic --name utopic-backup /dev/md0 lvconvert --splitmirrors 1 --trackchanges faldara/utopic --name utopic-backup /dev/md0 The idea was to start using the new drive exclusively while keeping a backup on the old drive. Also I thought it was a bit odd that --splitmirrors accepted the - --name argument, but silently ignored it, instead using an internal auto generated name. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBCgAGBQJUiPAZAAoJENRVrw2cjl5RAS0H/10hFYNUF8n71iXER0iQVAtd bHauiQBbemml3Q1RgqWHCFj2SYQB0epACFHIdyDUC2kWaNyQ7A9VnbRPsnyEGLzo Tu2+LjbH2QA1e8J9zHQYq8BO0jHay5n/1S/JZrhUHxW0hyI3vnsVXESNA4GUntqn tcC7N+wzu8SUIuqjtcm30kEE0ZvzlDv4znADIudJzXJu7JE+TjhIljg5YWY8NBxE AYbUc1f8tGKzIyzehPETpq6/Hsi4C8C27nw+kugs+HvrmWO29nqhjQczXlbYfvjL SDNsXLMj68dkjSqJzuuK0jy6HlHgrPxJJtaGfJ92TIcFbm9gVJHWfqClzbd1vao= =am39 -----END PGP SIGNATURE-----
