Well, your report is unfortunatelly missing a lot of basic information. So please try to open proper lvm2 bugzilla at bugzilla.redhat.com. If you are not a Fedora user - pick just fedora system. We need to know your OS name and version. Version of the lvm2 tools package. Preferable metadata backup (vgcfgbackup) And '-vvvv' trace from hanging command. > > Symptoms are: message at boot: > [ 15.668799] device-mapper: table: 252:3: snapshot: Snapshot cow pairing > for exception table handover failed > [ 15.668934] device-mapper: ioctl: error adding target to table > [ 19.388627] device-mapper: table: 252:3: snapshot: Snapshot cow pairing > for exception table handover failed > [ 19.388786] device-mapper: ioctl: error adding target to table > I guess you activation command (vgchange -ay) should be giving you some error messages - try to use -vvvv and attach to bugzilla.

Note - you cannot manipulate individual snapshots - with old (non-thin) snapshot you always work with all snapshots and its origin at the same time.
