Hey, I'm kinda new to Proxmox, so hopefully you can help me out with my problem.

I have a storage with a size of 333.7GB called "local-lvm (proxmox)". It has reached its limit, so now I want to increase the size.
Using "lsblk" in shell I could see, that I have 2 another drives available on that device, which have 1.8tb space how i can use that 2 drives in proxmox?

root@proxmox ~ # lsblk

Theoretically you could partition the free unpartiotioned space left on sdb and sdc, create a file system on those (ZFS for shared, or two separate) add add that to the Proxmox VE storage configuration.

Note, your setup uses md RAID, which is not officially supported by Proxmox VE..
Also, your root partition is on a RAID0, if any of the three disks fails you wont be able to boot anymore...

But how i can use setup without md RAID? i can't increase disk size from 333GB to more or in TB i tried every method but still same issue. Should i leave server?
 
Now i have this data after fresh install

when i run pvcreate i got this error

root@proxmox ~ # pvcreate /dev/sdb1
Device /dev/sdb1 excluded by a filter.
 
It look like it's doable to move your / mount to another partition.

But if you can do a fresh install that would be much better.

Regardless of that you should be able to create new partition on the available space of your drive.
Do you have an error message when you write fdisk ?
Getting this log on check fdisk
