Full Discussion: Disk /dev/sdb doesn't contain a valid partition table

Is it possible that the whole drive was LVM'd (as a PV)? Partition tables can be a bit "old school" today.

Try pvs or pvscan see if that helps (just a guess, an idea).

NAME

       pvscan - scan all disks for physical volumes

SYNOPSIS

       pvscan  [-d|--debug]  [-h|--help]  [-v|--verbose]  [--version]  [--ignorelockingfailure]  [-e|--exported] [-n|--novolumegroup] [-s|--short]
       [-u|--uuid]

       pvscan [-d|--debug] [-h|--help] --cache [--major major --minor minor | DevicePath ] ...

DESCRIPTION

       pvscan scans all supported LVM block devices in the system for physical volumes.

OPTIONS

       See lvm(8) for common options.

       -e, --exported
              Only show physical volumes belonging to exported volume groups.

       -n, --novolumegroup
              Only show physical volumes not belonging to any volume group.
