Create a new logical volume

Move ISO storage

Note: This example uses the data_2tb group as base and ISO as the datastore to be created. Change this according to need.

• Create logical volume (example is 32GB): lvcreate -V 32GiB -T data_2tb/data_2tb -n ISO
• Format new volume: mkfs.ext4 /dev/data_2tb/ISO
• Make mount point: mkdir /mnt/ISO
• Mount logical volume to mount point: mount /dev/data_2tb/ISO /mnt/ISO
• Test write a file to the new volume: dd if=/dev/zero of=/mnt/ISO/test bs=1M count=1024
• If the test works correctly, then remove the test file: rm /mnt/ISO/test
• Go to Proxmox GUI and add the new location:
  1. Go to Datacenter
  2. Storage
  3. Add, and add the new storage into Proxmox.
     • Use iso for ID
     • /mnt/ISO for Directory
     • Select the appropriate content for this datastore
• List ISOs in the default location: ls -lh /var/lib/vz/template/iso/
• Move ISOs to the new location: mv /var/lib/vz/template/iso/*.iso /mnt/ISO/template/iso

Note: If you only want to move a specific ISO, then move just the required file, example: mv /var/lib/vz/template/iso/netgate-installer-v1.0-RC-amd64-20240919-1435.iso /mnt/ISO/template/iso

Make the new datastore available after reboot

Edit /etc/fstab and add the new datastore to the end.
