In a bit of a panic mode here so I will try to put in everything I can think of and sorry if I missed a thread or any other needed info, please link me to it or let me know and I will follow up.

Been running a Proxmox server for a few years now and finally needed to upgrade my OS HDD... I cloned a 250GB SSD onto a 1TB SSD, got the drive up and running and expanded as well as expanding one of my VM's. I then left the state...

Today I got some calls that my services were down and when I jump on the machine I had read only errors on the VM and had to repair... Spent some time on this and decided I have docker containers so I would just clone the drive and reinstall the OS... Thats when I hit the wall...


ERROR:
update VM 102: -virtio3 local-lvm:250
WARNING: Remaining free space in metadata of thin pool pve/data is too low (100.00% >= 94.74%). Resize is recommended.
TASK ERROR: lvcreate 'pve/vm-102-disk-1' error: Cannot create new thin volume, free space in thin pool pve/data reached threshold.


So I went looking and found:

root@pve:~# pvs

/dev/sdb1 Raid-6 lvm2 a-- <25.47t <1.45t

So I went to googling and I found a few threads to educate me some on LVM Metadata (always learning so please feel free to poing out anything I missed PLEASE)... I found the following thread: Increase lvm thin what about metadata

Which I BELEIEVE leads me to the fact that the only way to fix this is to re-create the LVM in order to fix the metadata issue. This is where the questions and problems actually start...

Since I am not in the same state as the server I have no physical access to it, so is there a way to recreate this without losing all my data?

Or...

Do I need to buy and setup another 1TB HDD (I actaully have a clone of the server local to me so all chipset and such would be the same) and ship it and have someone install it and start copying over my VM's and setting's?

ANY help here would be greatly appreciated...
