Unable to complete update to v7.4.0 (Ubuntu 20.04.2 LTS)

[p44]

@girish Thank's a lot, what I have to check ?

I saw different errors like this:

failed to register layer: Error processing tar file(exit status 1): write /root/.npm/_cacache/content-v2/sha512/74/89/c8...7b6560d2a8a8: no space left on device

But it seems this is an error due to space left on device, that occurred after lunched the update.

Edit: I tried to update again, but few seconds after lunching update, disk will be fulled again. I sent an email to support.

[girish]

@p44 so how much space is left on the device?

[p44]

@girish Usually the device has 6-6.5 GB free, but starting update it will full...

[girish]

I think this is just the server disk space being super low (~19GB). There was an exception in the logs:

[ERROR] AssertionError [ERR_ASSERTION]: ifError got unwanted exception: Create table/tablespace 'oidcClients' failed, as disk is full
    at /home/yellowtent/box/node_modules/db-migrate/lib/commands/on-complete.js:15:14

I managed to update it in a hacky way but I guess we need around 25GB total server space when transitioning over to new docker images.

[p44]

@girish So new docker images need more space? I see, it takes the double of space?

[girish]

@p44 It takes extra space for a short amount of time. It's like this:

1. Old containers are running
2. New images are downloaded
3. Old containers are stopped.
4. Old images are removed
5. New containers are started

We can do step 3 and 4 before step 2. But this means that you will have more downtime. So, it's a compromise made assuming that servers have disk space (which most of them do).

I am running into the exact same problem that my disk space is running low. In this context, I want to switch to another VM. Is it possible to install a fresh copy of Cloudron 7.4.1 on the new server and then import a backup of one single app from the old Cloudron instance? The app version is the same, however, the cloudron version is different due to the fact that I cannot update the old instance.

[girish]

@hcj-online in the new VM, simply install with cloudron-setup --version 7.4.0. Also, another option is to just increase the disk size of your current VM (if that's possible).

@girish what I can see is that after update, "Docker" takes 9.25 GB disk space. Before update it was only 4.51 GB... So my question is: new release requires more disk space?

[girish]

@p44 can you check if running docker image prune -a frees up some space?

[p44]

@girish I did, but the space is the same.

[girish]

@p44 thanks, I have to double check this in a fresh install then.

[girish]

On my existing install, docker takes around 7GB.

On a fresh install:

root@ubuntu-s-1vcpu-2gb-sfo2-01:~# docker system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 9 0 6.905GB 6.905GB (100%)
Containers 0 0 0B 0B
Local Volumes 0 0 0B 0B
Build Cache 0 0 0B 0B

So, the size hasn't changed much (atleast for docker images). Not sure what apps you have installed. Maybe they are taking lots of space?

[girish]

With VPN app installed:

[p44]

@girish Thank's Girish, I've only one VPN app. The docker before update it was 4.5 GB, now is around 7 (yesterday it was 9)...

[girish]

@p44 the VPN app got the base image update just yesterday. So that frees up some space.

@girish Thank's
