2. Refer to answer 01: Create one or more physical partitions as a PV

# pvcreate /dev/sdb{1,2}physical volume  "/DEV/SDB1"  successfully createdphysical  volume  "/DEV/SDB2"  successfully created# pvs           #<-  View PV Information pv           in the system        vg   fmt      attr      PSize     PFree/dev/sdb1                lvm2      ---        1.00g     1.00g/dev/sdb2                lvm2      ---        1.00g     1.00g# pvdisplay     #<-  SearchSee system PV for more details 

02:VG configuration (assuming the creation of a 2G VG, i.e. two 1G of PV)

# vgcreate myvg/dev/sdb{1,2} Volume Group "MYVG" successfully created# vgsvg #PV #LV #SN Attr vsize VF REEMYVG 2 0 0 wz--n-1.99g 1.99g

The configuration of the LV

# lvcreate-l 50m-n TESTLV MYVG rounding up size to full physical extent 56.00 miblogical Volume "TESTLV" created

Description: L represents the size of the logical volume created, the default PE is 8M, so 8 cannot be divisible by 50M, so the logical volume created is larger than 50M
