Help with mount points on CentOS

[dbwillis]

this isnt for me, but Im not too up on Linux.
I have a request from a developer that needs to add space for backups to complete "Mount point: /mongobackup (Add 100GB) ", he provided a lswwn info:
This is a VM (ESX) I was going to expand the SBC drive from 50gb to 150gb, but in his list, I see "mongobackup" on SDA, SDB and SDC, he isnt sure why 3 are listed,I have no access to log into it though

You need to add a new disk and then follow this guide and add it to correct LVM

Thanks, I dont have login access to the VM, so I just expanded the 50GB SDC drive to 150GB and advised the developer to expand the disk in the OS
