Nextcloud Snap not working

panicos · August 16, 2021, 11:16am

Hello all,

I have been running Nextcloud Snap deployed in a VM for the last year without problems. Now i have upgraded my esxi host and apparently, Nextcloud is not working anymore. I can ssh into the machine but don’t know what is the problem.
The nextcloud is deployed as a snap and the data directory is moved on an external share, mounted in the machine. Nextcloud is running on ubuntu 18.0.4.
I don’t know how to tshoot this problem, as my skills on it are 0.
I tried to google it and tried some tshoot steps and maybe the problem is regarding a wrong mapped path, but i am just assuming. What i can say is that i have done no modifications to the Nextcloud.
Here is an example of what i tried (not sure if it is the same problem):

root@robsrvnex:/snap/bin# ll

root@robsrvnex:/snap/bin# sudo nextcloud.occ files:scan --all
cannot create temporary directory for the root file system: Read-only file system
root@robsrvnex:/snap/bin#

I can add some logs and the php file config, but to be honest i cannot see where is the upload file button; i can oly add pictures.

Please, any suggestion would be very helpfull.

Thx.

Hi @panicos

Since you changed nothing on your Nextcloud installation or inside the VM where your Nextcloud is installed, the problem lies most likley somewhere in the ESXi configuration or on your file server. Maybe the ESXi upgrade has changed something in the network configuration of the VMs? I don’t know much about ESXi, so I can’t give you detailed instructions… But that’s where I would look for the issue first…

Advise: Documentation helps a lot in such cases. When you get it working again, write down all steps and configuration changes you made. This is not meant to be a smart-ass lecture, but I had to make this experience painfully for myself…

it is nothing wrong in the Esxi. i just re-attached the old VM in the new ESXi environment, very simple and basic job. The problem is in the VM (nextcloud), i am sure of that. I cannot run internal commands as i used to in the past (example already provided).

bb77 · August 16, 2021, 12:16pm

Sorry then I am a bit at a loss… Upgrading the hypervisor, should not actually change anything inside the VM. In this case it would be helpful to know how exactly you set all up and mounted the external share in the first place. To me it looks like the Snap respective Ubuntu has no access to this share anymore, where the data folder is located…

panicos · August 16, 2021, 12:27pm

exactly, might be the case, although the mount is reachable from the VM itself.
I am attaching some logs and some config here:

That’s all that i could think off. Problem here is i don’t know where to search and what; don’t know what to look for in order to identify and fix the issue.

I have found this. But it looks ok to me, when I look at your config.php. The permissions of /mnt/DATA/NEXTCLOUD look fine as well. Unfortunately I can’t think of anything else. Maybe someone else here has any ideas, who is more familiar with the Snap package than me…

panicos · August 16, 2021, 2:20pm

I have found this.

Yes, i know this link; i configured the nextcloud based on it, about one year ago.

panicos · August 16, 2021, 2:48pm

additional errors i found in the console of the nextcloud:

errors

bb77 · August 16, 2021, 3:38pm

For me it looks like Nextcloud respective the Snap has no write access to the data directory… This could be some bug, some problem with how you mounted the share… I’m not quiete sure.

Maybe this thread helps at least to point you in the right direction…

panicos · August 16, 2021, 3:55pm

thanks, i will check that one also.

panicos · August 17, 2021, 10:13am

Maybe this thread helps at least to point you in the right direction…

tried that, not working. i already had it mounted with 0770

bb77 · August 17, 2021, 10:27am

Hmm, I’m running out of ideas…

Maybe you could spin up another VM, reinstall everything, and restore your backup. If it works you’re good, if not you would still have the old VM. Not the nicest “solution”, I know… At least the time needed to test this with the snap package should not be too long…

panicos · August 18, 2021, 8:38am

yeah, well. reinstall works. i mean, this was not a tshooting, but just a completely new setup - erase the old machine, build another one.

bb77 · August 18, 2021, 8:46am

Yeah not the most elegant solution But good to hear everything is up and running again…
