LXC containers do not start when disk is installed on NAS

[hitymca]

Hello, I am having an issue where lxc containers do not start when i choose my NAS as the storage. VM's work just fine with the same storage configuration. That tells me (at least i'm pretty sure) that this is not a network or permissions problem but something to do with the LXC. The .raw file is being created on the NAS so the node is able to write to the NAS with no issues

This is the error when trying to start.

run_buffer: 571 Script exited with status 255
lxc_init: 845 Failed to run lxc.hook.pre-start for container "102"
__lxc_start: 2034 Failed to initialize container "102"

I don't see anything outstanding with your config.

Has this container ever been built? I'm guessing not. I'm thinking that maybe it is not managing to handle the creation due to the template location. (Is that template on the same nas or is it in that storage local?)

Have you managed successfully to spin up that same LXC but on a different storage location? What happens if you then try & move the LXC's disk to that nas storage.

So far i have only tried it with the template on the same nas storage but yes if I do template and disk on local storage it builds and starts just fine. I did just try to move it to the nas storage but then it would not start and I cannot move it back now.

I did just try to move it to the nas storage but then it would not start and I cannot move it back now.

How did you move it? Stopped the LXC & then GUI; CT Resources, Root disk, Volume Action & Move Storage? It seems strange you could move it to the NAS but not back again. (I assume you don't have any snapshots for that LXC). Something on the NAS side may not be right.
