mmvdisk: Total capacity is the raw space before any vdisk set definitions.
mmvdisk: Free capacity is what remains for additional vdisk set definitions.
[ess3ka ~]#
12. Allocate the new space by using the mmvdisk command set.
An example of adding the new storage to an existing file system is as follows:
a. Define a vdisk set that is tied to the existing recovery group.
[ess3ka ~]#
mmvdisk vdiskset define --vdisk-set vs_ess3k_1 --recovery-group ess3k_mySN --code 8+2p
--block-size 4m --set-size 40%
mmvdisk: Vdisk set 'vs_ess3k_1' has been defined.
mmvdisk: Recovery group 'ess3k_mySN' has been defined in vdisk set 'vs_ess3k_1'.

b. Create the newly defined vdisk set.
[ess3ka ~]#
mmvdisk vdiskset create --vdisk-set vs_ess3k_1
