R7800 Error: No space left on device - Trying to install Entware

[Giaki]

Hi,
I flashed the latest Voxel firmware on a R7800 (75.2) and I decided to try to install Entware.
I went through the readme but when I arrived at creating the swap file I got an error that said I hadn't enough space on my usb flash. I read that that was an optional step so i skipped this but maybe this is the cause of the problem I econtered later, "Error: No space left on device".
So I couldn't finish this step:
"Reboot router again. After this use “/opt/bin/opkg update” and “/opt/bin/opkg upgrade” Entware repository. Install and use necessary for you packages."

Was an usb flash drive supposed to be left connected to the router to use Entware?
Should I make a swap file before on the flash drive using gparted?

Thank you

How big is your USB drive? How is it formatted? How much free space does it actually have (on a PC, for example)?

As far as I understand you try to install Entware into internal flash of your router. Check my README and clear your /opt directory from Entware/swap. "/opt" by default is internal memory flash. "bin", "etc", "home" etc should be symlinks in /opt. But not ordinary directories. You have to install initial Entware from my tarball. Reboot router. etc. README.

The pendrive is 16gb, ext2, almost empty, only entware tar inside.
Maybe the problem was that I removed the pendrive after I install the initial Entware, I didn't know that only 32mb of flash memory is actually available on the router and that I was supposed to leave a pendrive mounted in to extended the router's memory via symlinks.
To clear out /opt and /swap I can simply delete all files inside those foldcrs?
And to make the swap file, should I create it earlier with gparted?
Thank you again

edit.
I did it from scratch, same problems.
This time I left the usb drive connected to the router, created the swap file, copy paste these commands:
mkswap swap
chmod 0600 swap
swapon swap

After reboot (copy-paste from console):

I think it's trying to install packages on the internal memory, what I'm missing?
Thank you

To clear out /opt and /swap I can simply delete all files inside those foldcrs?

(1) /opt
Yes, just remove everything from /opt. I.e. run the commands:

rm -rf /opt
reboot

(2) /swap
Swap should NOT be created at the root location of your router! Again: please check README. It should be on your USB drive i.e. /mnt/sda1/swap. I.e. to fix it:

rm -f /swap
reboot

(3) Use ext4 instead of ext2: it is more advanced and more safe for your data. How: see (4) below.

(4) Run the steps (1) and (2) from the post:

https://www.snbforums.com/threads/c...4-2sf-v-1-0-2-74-3sf.61962/page-3#post-557147

after that:

cd /mnt/sda1
wget https://voxel-firmware.com/Downloads/Voxel/Entware/entware-cortex-a15-3x-initial-generic.tar.gz
tar xf entware-cortex-a15-3x-initial-generic.tar.gz
dd if=/dev/zero of=swap bs=1024 count=1048576
mkswap swap
chmod 0600 swap
reboot

(5)
And only after that

/opt/bin/opkg update
/opt/bin/opkg upgrade

I followed all you instructions but same error.
Can't understand what's wrong.
I take out the pendrive, turned off the router, format the pendrive to ext4 with my linux NB, plugged pendrive to the router and then did these commands:

mkfs.ext4 -L optware -O ^64bit /dev/sda1
tune2fs -O ^metadata_csum /dev/sda1
cd /mnt/sda1
wget https://www.voxel-firmware.com/Downloads/Voxel/Entware/entware-cortex-a15-3x-initial-generic.tar.gz
tar xf entware-cortex-a15-3x-initial-generic.tar.gz
sync
reboot
cd /mnt/sda1
dd if=/dev/zero of=swap bs=1024 count=1048576
mkswap swap
chmod 0600 swap
swapon swap
reboot

no errors.

The last two instructions (update and upgrade) are writing on the internal memory, I suppose.

At least one serious problem. After your experiments. Your internal flash is over.

. . .
ubi0verlay_volume 49.8M 49.8M 0 100% /overlay
overlayfs:/overlay 49.8M 49.8M 0 100% /
. . .

No space left. Well. Your USB seems OK. But internal flash... Is not a secret why do you want to use Entware? Seems you are not so experienced in Linux administration, sorry...

Simplest way for you is to reset to factory settings. And to install your configuration manually. To free your internal flash.

Or if you think that you can do: all your changes are visible in /overlay. It is necessary to clear your wrong steps e.g. swap file or whatever else. I do not know what else there. Maybe entware. If you think that you can do it. Rest (already prepared Entware) is already OK: on your USB. Please do all this with no USB attached.

Thnk you for all your support, yes, I just starded learning Linux stuff, I'm sorry if I'm doing silly mistakes or asking obvious things.
I'd like to use Entware to try adguard and wireguard (next thing to learn).

I unplugged the usb drive, did a reset via the hole behind the router. ssh key is still there so I can connect either telnet and ssh.
But overlay_volume is still full, I tried to delete /opt from inside ovelay folder but overlay is still full (strange).

Tried mnt erase volume_overlay but I got an error, either from ssh and telnet:
Could not open mtd device: overlay_volume
Could not open mtd device: overlay_volume

Any suggestion how can I format overlay?
Thank you

I'm sorry if I'm doing silly mistakes or asking obvious things.

Do not worry. No problems with this.

I'd like to use Entware to try adguard and wireguard (next thing to learn).

Well. Adguard? No such package in Entware as far as I know. There is kamoj add-on allowing to block ads. Wireguard. First, you are using R7800 and it could support only wireguard-go. Second: will be not so fast vs e.g. OpenVPN client. Plus wireguard-go additional package (+wireguard-tools) does not require installation of Entware.

Any suggestion how can I format overlay?

Better do not try to do that. You could brick your router.

Try to flash, say, any stock firmware. Reset to factory settings. And after that back to 75.2SF.

P.S.
Before doing this please publish here the output of

ls -al /overlay
ls -al /

Voxel.

 

[Giaki]

Well... I meant ad-block of course
Still experimenting about adblocking, don't know if it's better doing this with a raspberry pi 4 (I tried adguard and pihole) or doing directly with the router.

Good to know Wireguard-go vs OpenVPN, I thought that Wireguard was way better than OpenVPN. I could give a try to OpenVPN thus (150-30 FTTC).

I wanted to try also kamoj add-on but I messed up the overlay so can't do any tinkering at the moment.

Here is the output:

Voxel, is Entware supported on Orbi? I see that DNSCrypt and a couple of other items are in your release notes. I didn't see Entware listed...

You probably missed this info. Check my QuickStart.txt in ZIP with Orbi firmware:

. . .
4. Entware.
You can use Entware prepared by me for R7500/R7800/R9000. It works fine with Orbi.
(1) Prepare new USB stick or disk with ext2 or ext3 or ext4 filesystem from telnet/ssh
. . .

And BTW Entware is updated a bit. Including netdata.

/opt/bin/opkg update
/opt/bin/opkg upgrade

and do not download the package for its installation. Just:

/opt/bin/opkg install <package_name>

it is normal way to install the package. Downloading and installation manually from *.ipk for Entware is not needed as a rule.

Ok I wanted to confirm.

I had started the installation. Using a HDD USB drive connected to the back of the RBR. Same kind of drive I used yesterday on my R7800 which I got working well with Netdata.
I'm getting to this area during the setup:
mkswap swap< Not working on Orbi
I get a not found message: mkswap
I used the:
dd if=/dev/zero of=swap bs=1024 count=1048576 that proceeded the mkswap command.

Did I miss something? All was good up to the mkswap command.

Yes, you are right. I did not enable it for Orbi firmware. "I'll do in the next release. Use of swap is optional...

Meanwhile there is a workaround:

(1) Install swap-utils from Entware:

/opt/bin/opkg update
/opt/bin/opkg upgrade
/opt/bin/opkg install swap-utils
mkswap swap

(2) Change a bit /mnt/sda1/autorun/scripts/post-mount.sh by e.g. nano editor:

nano /mnt/sda1/autorun/scripts/post-mount.sh

Change
/sbin/swapon $SWAP

to
/opt/sbin/swapon $SWAP

Save file, exit nano, reboot.

[e38BimmerFN]

Ok will give this a try...

 

[e38BimmerFN]

Voxel, I'm try to do this again. I think that the tar file isn't being unpacked after it's downloaded:
cd /mnt/sda1
wget https://voxel-firmware.com/Downloads/Voxel/Entware/entware-cortex-a15-3x-initial-generic.tar.gz
tar xf entware-cortex-a15-3x-initial-generic.tar.gz
Reboot RBR

root@RBR50:/# ls -l /opt/*
lrwxrwxrwx 1 root root 16 Apr 4 16:56 /opt/bitdefender -> /mnt/bitdefender

root@RBR50:/tmp/mnt/sda1# ls -l /opt/*
lrwxrwxrwx 1 root root 16 Apr 4 16:46 /opt/bitdefender -> /mnt/bitdefender
Is all I see...

I can't do
/opt/bin/opkg update
/opt/bin/opkg upgrade as this causes the following message: /opt/bin/opkg: not found
Let me know what I'm missing...

 

[R. Gerrits]

tar xf entware-cortex-a15-3x-initial-generic.tar.gz

shouldn't that be "tar xzf entware-cortex-a15-3x-initial-generic.tar.gz" ???
Because it is a .tar.gz?

otherwise, check if /mnt/sda1/autorun/scripts/post-mount.sh exists an can be executed. That script is responsible for enabling entware after reboot.
