Increased LUN size, forgot how to update Mount point in lxc. help?

[miztahsparklez]

I'm in the process of increasing the size of my iSCSI LUN that I have attached via a mount point to one of my LXC. The filesystem is RAW. I've previously gone from 20TB to 22TB without issues and have recently tried to add another 2TB for a total of 24TB.

For the life of me, I can't find the thread/command I used to update this to leverage the maximum space.

I've already done pvresize and lvextend. The host sees the additional space without issue. I believe where I am being held up is the mount point size.

Trying through the GUI, I get an "insufficient free space" error and, of course, any of the file system expansion commands don't apply due to the raw file system.

Any thoughts on what I might be missing?

Hi @miztahsparklez , welcome to the forum.

The filesystem is RAW.

This is an oxymoron - a filesystem is the opposite of raw disk.

Perhaps, if you add some technical details, the community might be able to guide you in the right direction. I.E.:
lsscsi
pvs
vgs
lvs
lsblk
pct config [id]

Thanks bbgeek17. Sorry I'm not super up to the technical terms here as this is my first proxmox experience!


So here you can see that my volume group here is 24tb

  PV             VG          Fmt  Attr PSize   PFree
  /dev/sda       Proxmox-LUN lvm2 a--  <24.00t     0

Logical volume

LV              VG          Attr       LSize    Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  vm-10443-disk-0 Proxmox-LUN -wi-ao----  <24.00t

lsblk

NAME                              MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda                                 8:0    0    24T  0 disk
└─Proxmox--LUN-vm--10443--disk--0 252:14   0    24T  0 lvm

Here's where I think I am not seeing the change or able to update/increase.
pct config

mp1: LVM-Proxmox:vm-10443-disk-0,mp=/mnt/scrypted-nvr,mountoptions=noatime,replicate=0,size=22020092M

Well, there is a file system that sits on top of the LV. You can run "blkid" to get more information.
You will need to expand the file system, it does not happen automatically. As for the "size" option - it is not critical, I believe. You can try :

from: man pct

pct rescan [OPTIONS]

Rescan all storages and update disk sizes and unused disk images.

--dryrun <boolean> (default = 0)
Do not actually write changes to the configuration.

--vmid <integer> (100 - 999999999)
The (unique) ID of the VM.

Perhaps the next step is:

pct resize <vmid> <disk> <size> [OPTIONS]

Resize a container mount point.

<vmid>: <integer> (100 - 999999999)
The (unique) ID of the VM.
