Your data directory is invalid Ensure there is a file called ".ocdata" in the root of the data directory. Your data directory is not writable Permissions can usually be fixed by giving the webserver write access to the root directory. See https://docs.nextcloud.com/server/18/go.php?to=admin-dir_permissions.

Hi, I’m ready. What do you need me to do?

[enoch85]

Let's keep the everything in one issue.

This is also related: #1203

I'll have a look at Hyper-V deployment tomorrow, it's bed time here.

[enoch85]

So I think I may have a solution.

Please try this script: https://github.com/nextcloud/vm/blob/master/static/change-to-zfs-mount-generator.sh

Before you run it, make a snapshot of your VM and:

1. Download the RAW file via CLI (wget file.sh)
2. Run it with sudo bash file.sh
3. Reboot
4. Post the outcome here.

Thanks!

Thank you, Daniel. I’ll try this in the morning Had to deal with some power issues Tues evening. And it finally coming back early this morning. So, havnt been able to play with the VM I did figure out that the .ocdata issue was because there was nothing in the /mnt/ncdata folder. I touched it. Now i have a permissions issue. Since i have time i dont mind figuring it out myself. I’ll try your steps tomorrow. See what happens. John

Important before you run the script: remove any changes you did to /mnt/ncdata

So in your specific case, I would:

1. sudo -i
2. rm -rf /mnt/ncdata (zpool list is empty)
3. Follow the steps above

[enoch85]

OK, I just got it confirmed, the fix works on a broken system.

@jwallmon Could you please also confirm?

I will push this to master now

[jwallmon]

Ok... took me a bit of time to figure out how to get the raw file from github. I work with Windows computers all day & still figuring out the behind the scenes of Ubuntu. Yep. It also worked for me. No more ZFS error when it boots up. I made it to the logon screen & am now logged in. Now I can work on configuring it for our company- Active Directory, Outlook integration, etc. Thank you. John

[enoch85]

Thank you very much for confirming! Now I feel confident this is the fix.

Have a nice weekend!

FYI: This is now completely fixed. Just uploaded all new versions of VMs with the latest patch.

Unfortunately I have to run the ./change-to-mount-generator.sh file after every restart.

Is there a permanent solution here? Thanks in advance
