Only leaf data or log devices may be initialized. .Bl -tag -width Ds .It Fl c , -cancel Cancel initializing on the specified devices, or all eligible devices if none are specified. If one or more target devices are invalid or are not currently being initialized, the command will fail and no cancellation will occur on any device. .It Fl s , -suspend Suspend initializing on the specified devices, or all eligible devices if none are specified. If one or more target devices are invalid or are not currently being initialized, the command will fail and no suspension will occur on any device. Initializing can then be resumed by running .Nm zpool Cm initialize with no flags on the relevant target devices. .It Fl u , -uninit Clears the initialization state on the specified devices, or all eligible devices if none are specified. If the devices are being actively initialized the command will fail. After being cleared .Nm zpool Cm initialize with no flags can be used to re-initialize all unallocoated regions on the relevant target devices. .It Fl w , -wait Wait until the devices have finished initializing before returning. .El . .Sh SEE ALSO .Xr zpool-add 8 , .Xr zpool-attach 8 , .Xr zpool-create 8 , .Xr zpool-online 8 , .Xr zpool-replace 8 , .Xr zpool-trim 8
