rpm colgado

El sintoma es que el rpm -qa se queda colgado. La manera de solucionarlo fue matar los procesos asociados al rpm y reconstruir la base de rpm borrandola previamente.

error Can't open /dev/mapper/mp_u01 exclusively. Mounted filesystem?

Este error se produjo al intentar agregar o remover un disco

La solucion fue borrarlo con el dm-setup y volverlo a crear como se muestra a continuacion

# pvcreate /dev/mapper/mp_u01
  Can't open /dev/mapper/mp_u01 exclusively.  Mounted filesystem?
