[SOLVED] LVM disk size is different to VM creation

[zxsteve]

Good morning all.

I have just migrated from XCP-NG and I already love proxmox for its ease and simplicity!!
I have created me VM's ready to start transitioning services over however I have run into a little problem that I am not sure how to solve.

Physical setup
HP Proliant DL386 Gen 7 (?)
2x 10k 100GB setup in RAID 0 <-- Proxmox host
6x 10k 300GB setup in RAID 50 (RAID PArity = 2) <-- VM storage

I have three VM setup
1) homeServer, 100GB storage, ubuntu server
2) gameServer, 200GB storage, ubuntu server
3) mediaServer, 500GB storage, ubuntu server

I started copying media files over to VM 3 and very quickly ran out of space. (This is an identical setup to xcp-ng so I know it will fit!)

My media comes to just over 100GB in size

When I check the machine I have found that the LVM is not sized to the full 500GB

output from df -h

Filesystem	Size	Used	Avail	Use%	Mounted on
tmpfs	795M	1.1M	794M	1%	/run
/dev/mapper/ubuntu--vg-ubuntu--lv	98G	6.8G	87G	8%	/
tmpfs	3.9G	0	3.9G	0%	/dev/shm
tmpfs	5.0M	5.0M	0	0%	/run/lock
/dev/sda2	2.0G	127M	1.7G	7%	/boot
tmpfs	795M	4.0K	795M	1%	/run/user/1000

however the output from lsblk is
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
loop0 7:0 0 62M 1 loop /snap/core20/1587
loop1 7:1 0 79.9M 1 loop /snap/lxd/22923

loop3 7:3 0 55.6M 1 loop /snap/core18/2566
loop4 7:4 0 118.4M 1 loop /snap/docker/1779
loop5 7:5 0 1.1M 1 loop /snap/mosquitto/776
sda 8:0 0 500G 0 disk

└─sda3 8:3 0 498G 0 part
└─ubuntu--vg-ubuntu--lv 253:0 0 100G 0 lvm /
sr0 11:0 1 1024M 0 rom

sda3 shows 498G!! but ubuntu--vg-ubuntu--lv is only 100G in size

I checked the rest of the VM's and they are the same gameServer only used 100G of the 200G available!

Please can someone help me to use the full space on the ubuntu lv

Thanks in Advance
