The partition maps were apparently created with kpartx's "-p p" option
to force a partition separator of 'p' (the default is to use a 'p' if
the device name ends with a numeral but no separator otherwise).
If the maps were created with -pp kpartx will refuse to remove them if
the option is not given (but helpfully doesn't report any error.. :-/):
# ls /dev/mapper/vg_mother-lv_base*
/dev/mapper/vg_mother-lv_base /dev/mapper/vg_mother-lv_basep1
# kpartx -d /dev/mapper/vg_mother-lv_base
# ls /dev/mapper/vg_mother-lv_base*
/dev/mapper/vg_mother-lv_base /dev/mapper/vg_mother-lv_basep1
# kpartx -d -pp /dev/mapper/vg_mother-lv_base
# ls /dev/mapper/vg_mother-lv_base*
/dev/mapper/vg_mother-lv_base
Just add the -pp to your kpartx command lines and it should remove the
devices.
Regards,
Bryn.
