如何配置 LVM 以使用整个分区

由于空间紧张，/dev/sdb 上的 HDD 大小已从 500 GB 增加到 650 GB，但不确定如何调整 lvm 大小以利用可用的 150GB。

sdb         8:16   0   650G  0 disk
└─ceph--ef9893e6--7191--434e--a531--8deaeb51ad92-osd--data--5abbfff8--920a--419d--bb87--91ba4a1bf3a1
          253:0    0   500G  0 lvm

尝试了 lvextend 但失败了。

lvextend -L+12G /dev/ceph-ef9893e6-7191-434e-a531-8deaeb51ad92/osd-data-5abbfff8-920a-419d-bb87-91ba4a1bf3a1
  Insufficient free space: 3072 extents needed, but only 0 available

lvextend -l +100%FREE /dev/ceph-ef9893e6-7191-434e-a531-8deaeb51ad92/osd-data-5abbfff8-920a-419d-bb87-91ba4a1bf3a1
  New size (127999 extents) matches existing size (127999 extents).
