Create Flexible Disk Storage with LVM Part I; When do we need to reduce volume? Within the volume groups in Figure 5.1, Physical Partitioning versus LVM, four logical volumes (LV 1 through LV 4) have been defined, which can be used by the operating system via the associated mount points (MP).The border between different logical volumes need not be In the pop-up window that appears, specify the amount to shrink the volume in Megabytes.

If the LVM volume is containing any required data, then please make sure to take a backup of that data before proceeding with following steps: In this example, we will be deleting testlv from the volume group datavg. With no arguments, you are presented with seven different columns : VG : describing the volume group name on the host;; #PV: displaying the number of physical volumes available in the volume group;; #LV: similarly, the number of logical volumes created out of the volume group;; #SN: number of snapshots created out of the logical volumes;; Attr : describing the attributes of 7. Note: when started with the PORT environment variable, the image will just the Docker daemon and expose it over said port.
