How to configure LVM to use the entire partition

Due to the space crunch, have increased the HDD size from 500 GB to 650 GB on /dev/sdb, but unsure on how to resize the lvm to make use of the available 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

Tried lvextend but failed.

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).

Looks like you have unallocated space on sdb. You can resize the existing partition and then extend the filesystem or you can create a new partition and add it to the volume group. This is a good guide https://www.tecmint.com/extend-and-reduce-lvms-in-linux/

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
