To  change\nthese values, first use pvremove on the device.\n\n",

Each VG and LV has an allocation policy which can be changed with\nvgchange/lvchange, or overriden on the command line.  normal applies common sense\nrules such as not placing parallel stripes on the same PV.  inherit applies the VG\npolicy to an LV.  contiguous requires new PEs be placed adjacent to existing PEs.\ncling places new PEs on the same PV as existing PEs in the same stripe of the LV.  If\nthere are sufficient PEs for an allocation, but normal does not use them, anywhere\nwill use them even if it reduces performance, e.g. by placing two stripes on the same\nPV.  Optional positional PV args on the command line can also be used to limit which\nPVs the command will use for allocation.  See lvm(8) for more information about allo‐\ncation.\n",
