I have an existing Proxmox 7.4 installation on a device with a hardware RAID controller. I recently changed RAID levels on said hardware controller and enlarged the hardware RAID's single logical volume to fill the additional space, creating additional space on the single disk visible to Proxmox. Here is what
Note
I would like to extend
I am looking for a solution that preserves the existing contents of my local/local-lvm drives and my VMs but allows me to grow them. I can boot to installation media if necessary, but obviously it'd be easier if I could do this all from within proxmox. Can I safely resize
fdisk -l
outputs on the proxmox node:
Code:
The backup GPT table is not on the end of the device.

Note
/dev/sda
is 4.91 TiB, whereas /dev/sda3
is only 3.3T large.I would like to extend
/dev/sda3
to fill the remaining empty space, and I would then like to update proxmox to use this space. Resizing the logical volumes within proxmox seems like the easy part, but I have to first extend /dev/sda3
, and my limited research shows this may cause disaster (but I haven't found much documentation on the subject either way, so...)I am looking for a solution that preserves the existing contents of my local/local-lvm drives and my VMs but allows me to grow them. I can boot to installation media if necessary, but obviously it'd be easier if I could do this all from within proxmox. Can I safely resize
/dev/sda3
to the end of the disk without concern, or are there additional steps necessary to safely expand proxmox? Or should I establish another partition in the empty space? Or something else?
