Hello,

When I first setup Proxmox I did not do a good job of ensuring that my configuration was documented.

I am currently dealing with the following and I am struggling to ensure I do it correctly and without causing any issues.

  1. I want to increase the size of local (rawafidmain) where our scheduled backup reside
    1. I want to allocate non-partitioned space.
    2. There currently exist 2 partitions /dev/sdb and /dev/sdc
    3. I have absolutely no idea which one currently houses which logical volumes
  2. I want to ensure that external server backups are performed (to a USB). How can I do that through Proxmox?

Any help or clues that is not a synonym of RTFM would be greatly appreciated (cause I am using the documentation/manual to do this).

Thank you!
Reem

Please provide the output of the following commands:
lsblk
lvs -a
vgs
pvs
cat /etc/pve/storage.cfg
 
@mira thank you so much for your response. It was the weekend and I only ended up executing your commands just now.

zfspool: zpool1
        pool zpool1
        content images,rootdir
        mountpoint /zpool1
        nodes rawafidmain
 
Sorry for the delay, just got back from my annual leave.

The following disks are on your local-lvm:
Code: 
vm-102-disk-0   pve Vwi-a-tz-- 500.00g data        1.44
  vm-103-disk-0   pve Vwi-a-tz--  32.00g data        35.03
  vm-105-disk-0   pve Vwi-a-tz--  32.00g data        79.11
  vm-106-disk-0   pve Vwi-aotz--  48.00g data        63.67
  vm-107-disk-0   pve Vwi-aotz--  47.00g data        70.22
  vm-108-disk-0   pve Vwi-a-tz--  32.00g data        26.31
This means you can't simply remove storage from it and add it to your local storage.

/dev/sdb and /dev/sdc seem to be used by your ZFS, so they are out of the question as well.
Is /dev/sdd your USB storage?
