Hi, I'm trying to make the installation storage for software larger on my OpenWrt Virtual Machine on Proxmox. The VM is installed with the default settings in Proxmox VE Helper-Script.
My Problem
After reading the official post on Extroot configuration and trying to find the problem, I managed to narrow it down to lacking a overlay partiton.
Here is the result from df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 102.3M 23.6M 76.6M 24% /
tmpfs 115.7M 1.0M 114.7M 1% /tmp
/dev/sda1 15.7M 5.5M 9.9M 36% /boot
/dev/sda1 15.7M 5.5M 9.9M 36% /boot
tmpfs 512.0K 0 512.0K 0% /dev
Here is the result from block info
$ block info
/dev/sda1: UUID="..." LABEL="kernel" VERSION="1.0" MOUNT="/boot" TYPE="ext4"
/dev/sda2: UUID="..." LABEL="rootfs" VERSION="1.0" MOUNT="/" TYPE="ext4"
Where as in a video from youtube showed there should be a block device who's MOUNT is something like /overlay. So in the Configuring Extroot section, I got empty in the following command.
eval $(block info | grep -o -e 'MOUNT="\S*/overlay"')
What I tried
I added another disk to the VM and formatted it successufly with commands from the doc. As explained in the previous section, I thought I was just missing the /overlay partition, so I only changed the line which sets the variable MOUNT to the current path of overlay partition and runned the following commands
eval $(block info ${DEVICE} | grep -o -e 'UUID="\S*"')
MOUNT="/overlay"
uci -q delete fstab.extroot
uci set fstab.extroot="mount"
uci set fstab.extroot.uuid="${UUID}"
uci set fstab.extroot.target="${MOUNT}"
uci commit fstab
I was expecting contents in /etc/fstab, but it's just emtpy.
I'm stucked now and don't what to do next.
Possible improvement on the doc
It would be great if the result/purpose of some important steps can be included in the doc, so beginners like me can verify if I've done it correctly.
Thanks!
