119 .Pq i.e. module loaded, device present in Pa /dev .
120 This action can be safely performed while the virstor device is in use
123 Removes components from existing virtual device with the given
145 .Bl -tag -width ".Fl f"
147 Force the removal of the specified virtual device.
154 The following example shows how to create a virtual device of default size

162 .No gvirstor label -v Ar mydata Ar /dev/ada4 Ar /dev/ada6
166 From now on, the virtual device will be available via the
168 device entry.
169 To add a new physical device / component to an active virstor device:

206 than 2, because level 1 messages are error events, and level 2 messages
208 .Bd -literal -offset indent
212 Value in this sysctl sets warning watermark level for physical chunk
217 .Bd -literal -offset indent
