NCP datadir disappeared

Today my Nextcloud android app game me an error message and when i logged in to webui
This was waiting me.

But all the files seem to still exist as nextcloudPi control panel reports. Please help

Ive been running NCP on raspberry for 2 years now. couple of months ago moved to an ssd instalation

It would be useful to see /var/log/ncp.log and lsblk -f, and /var/www/nextcloud/config/config.php

    $CONFIG = array (
      'instanceid' => 'ocykypx5922v',

Trying to understand the output seems something broke in the backup before the update to 15.0.8
Something about not enough space left but i have almost 30GB free. But why did it lose the datadir because update failed?

And how to fix it :sweat_smile:

What btw happens if I have on my phone app calendar and photos that are newer than my nextcloud backup and then restore my something like 2week old backup (yes I know Im living too dangerously) will my newer photos and calendar fields disappear?

I know at least that much that this is wrong. I’m running pure ssd without other storage like sd card.
I’m trying to find out what is the default data directory. It seems no data has been lost (at least judging from the free space size)

no SD card? Output of lsblk -f and ncp-report and ncp.log?

It says there that you ran out of space

Yes I only have an 120GB SSD connected.

lsblk -f

`-sda2 ext4 rootfs 29075e46-f0d4-44e2-a9e7-XXXXXXXXXXX /

zram3 [SWAP]

But can I return an older backup? Will my newer calendar appointments disappear from phone where they still are visible when I connect it back to nextcloud?

I found the DB and Data directory’s. Everything seems to be still in tact.


Could I just in the NCP control webpanel set those paths in NC-Datadir and NC-Database?

don’t know what you did to empty the value of datadir, but you can set datadir in /var/www/nextcloud/config/config.php to /var/www/nextcloud/data (or wherever your datadir is)
