Issue

multipath -f and then dmsetup remove -f commands failed for a physical volume of an exported volume group. The commands were ran by a script. The commands worked fine for two PVs of the VG before.

Command return code after multipath -f mpath2 is 1 and error message :

mpath2: map in use

Command return code after dmsetup remove -f mpath2 is 1 and error message :

device-mapper: remove ioctl failed: Device or resource busy

Was able to remove manually the physical volume from multipathing. After that, script properly works with same volumes.
