How to mount drive to copy data

[bjamm]

Hey I created a new proxmox with 8.1 and attempting to copy my data over from the old ssd. It doesnt seem to let me mount it if you can help me go in the right direction in order to be able to boot or copy the vm from the old drive.

New drive is sdb
Old Drive is sda

I want the 32gb parition (vm100) thats listed under sda3 and move it to sdab 40gb but im getting the following error. Not sure what to try next.

root@pve:/# mkdir /mnt/adata
root@pve:/# mount /dev/sda3 /mnt/adata
mount: /mnt/adata: unknown filesystem type 'LVM2_member'.
       dmesg(1) may have more information after failed mount system call.

lsblk

root@pve:/mnt# lsblk

you need to use a tool like "dd" or "qemu-img" to transfer the block device contents. this can be a bit tricky if you don't know what you are doing.

ill look into that

is there a way to command line into the drive? I can't seem to get it to mount but if i can just download my firewall config file from the hd I can just rebuild the vm and restore the config instead.

that's probably more involved than just copying it..
