(v2.0.0-beta5) Failed to add swap (swapon failed: Invalid argument) about os HOT 6 CLOSED

I would try by having separate partition or disk for swap and by following https://burmillaos.org/docs/storage/custom-partition-layout/#burmilla_swap instead of partition file.

Also note that we looks to have search & replace failure on that guide, those partition labels should use prefix RANCHER_ instead of BURMILLA_ for backward compatibility.

Umm, I prefer swapfile.
It's pretty handy because it can be configurable within cloud-init.yml only.
I don't want to change the disk layout on every install.

I've perhaps read v2 kernel shares k3os's kernel code, somewhere.
Do you think this problem exists on k3os, too? (I don't have env/experience of k3os)

Ok. One big issue which I see is at least you are using folder /var/vm because in BurmillaOS console is also running inside of container and view to it is different that which kernel see.

With quick look to code at least folder /var/lib/rancher/cache should be mounted to both so if you use SWAP_PATH=/var/lib/rancher/cache/swap it would fix at least that part.

On other why I'm not aware that there would be anything which would prevent you from using swap file.

Ah, Ok. That sounds very reasonable.

(I don't know why above script works on v1.9.3, but :-)
I confirmed I can add a swap with SWAP_PATH=/var/lib/rancher/cache/swap.

I'll try to find is there any better location, but thank you for your advice!

Ok. Then it might be caused something else too.

I confirmed I can add a swap with SWAP_PATH=/var/lib/rancher/cache/swap.

But did it fix the issue?

Yes, it did.
At least, with the above path, it works as expected.
