       nvme-wdc-namespace-resize - Resizes the device's namespace.

SYNOPSIS

       nvme wdc namespace-resize <device> [--nsid=<NAMSPACE ID>, -n <NAMSPACE ID>] [--op_option=<OP OPTION>, -o <OP OPTION>]

DESCRIPTION

       For the NVMe device given, sends the WDC Vendor Specific Command that modifies the
       namespace size reported by the device.

       The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).

       This will only work on WDC devices supporting this feature. Results for any other device
       are undefined.

OPTIONS

       -n <NAMSPACE ID>, --namespace-id=<NAMSPACE_ID>
           Namespace ID; ID of the namespace to resize

       -o <OP OPTION>, --op-option=<OP OPTION>
           Overprovisioning Option; defaults to 0xF

               Valid Values:
               0x1 - 7% of Original TNVMCAP reported value
               0x2 - 28% of Original TNVMCAP reported value
               0x3 - 50% of Original TNVMCAP reported value
               0xF - 0% of Original TNVMCAP reported value (original config)
               All other values - reserved

EXAMPLES

       •   Resizes namespace 1 to 50% of the orginal TNVMCAP reported value:

               # nvme wdc namespace-resize /dev/nvme0 -n 1 -o 3

       •   Resizes namespace 2 to 7% of the orginal TNVMCAP reported value:

               # nvme wdc namespace-resize /dev/nvme0 --namespace-id=2 --op-option=1
