If a device +is mounted, the utility can unmount it automatically before +trying to deactivate. The utility currently supports +\fIdevice-mapper\fP devices, including \fILVM\fP volumes. +LVM volumes are handled directly using the \fIlvm\fP command. +Other device-mapper based devices are handled using the +\fIdmsetup\fP command. +.SH OPTIONS +.IP "\fB\-h, \-\-help\fP" +Display the help text. +.IP "\fB\-u, \-\-umount\fP" +Unmount a mounted device before trying to deactivate it. +Without this option used, a device that is mounted is not deactivated. +.IP "\fB\-d, \-\-dmoption\fP \fIdm_options\fP" +Comma separated list of device-mapper specific options. +.IP "\fB\-l, \-\-lvmoption\fP \fIlvm_options\fP" +Comma separated list of LVM specific options. +.SH DM_OPTIONS +.IP "\fBretry\fP" +Retry removal several times in case of failure. +.IP "\fBforce\fP" +Force device removal.
