Hi budy, getting back to this. This is what I get when I run the command grep: /var/www/nextcloud/config/config.php: Permission denied. I am logging in as ncadmin.
Thanks
For whatever reasons, the permissions on your files are wrong, if you can access them even read-only. What’s the output of
ls -l /var/www/nextcloud/
Stephan,
Here is what I get:
ncadmin@cloud:~$ ls -l /var/www/nextcloud/
ls: cannot open directory ‘/var/www/nextcloud/’: Permission denied
After the space issue, after logging in I now get:
Then you will have to work your way up - and you will need to be able to become the root user, otherwise you won’t be able to change permissions, once you figured out, what went wrong.
Try these:
ls -l /var/
ls -l /var/www/Stephan,
For the ls -l /var/ command I get:
ncadmin@cloud:~$ ls -l /var/

sudo grep -i datadirectory /var/www/nextcloud/config/config.php
this will give you access to config file if it is in /var/www/nextcloud. Output will show you where is your data saved. Example:
sudo grep -i datadirectory /var/www/nextcloud/config/config.php
'datadirectory' => '/var/www/nextcloud/data',
Did you install NC with snap, docker or manually?
I suppose you use snap, in this case if you run ps -ef | grep nextcloud command you will see similar output as in this comment: How to: change data directory in nextcloud snap - #4 by Igor_Danilov. In this case your data folder is probably under: /var/snap/nextcloud/common/nextcloud/data.
Stephan, I ran the command and get:
ncadmin@cloud:~$ sudo grep -i datadirectory /var/www/nextcloud/config/config.php
[sudo] password for ncadmin:
‘datadirectory’ => ‘/mnt/ncdata’,
the df command shows:
ncadmin@cloud:~$ df

This installation was a VM purchase from @enoch85. I though this would be the easiest way to get running for a Windows guy like me.
Would it hurt to follow this link? I don’t think it will help with NC but good general practice?
Thanks!
I have 6.2gb of data I want to keep in sync with NC After 2.5GB uploaded I get “Your storage is full files can not be updated or synced anymore!”
It might be that the appdata folder is very large, or that you (or your users) didn’t remove files stored in trashbin.
Set trashbin retention in config.php. You can find examples here: Configuration Parameters — Nextcloud 15 Administration Manual 15 documentation
That’s a start at least.
Hi Daniel,
Thanks for chiming in again!.. I will review the doc but have already ran:
sudo -u www-data /var/www/nextcloud/occ trashbin:cleanup --all-users
sudo -u www-data /var/www/nextcloud/occ versions:cleanup
and cleaned this up.
Am I missing something?
Thanks
Sorry, I don’t know all the ‘occ’ commands from the top of my head, but you can always check the docs.
Also, when using the VM you can use ‘nextcloud_occ actual:command’ instead if writing the whole path. 
So I was able to peck around the file system till i found where the data is kept. I thought there would be extraneous file not synced but its all good. I also searched around looking for appdata solutions. I came across this, Screwed up data/appdata_instanceid
Think following this will fix my issue? Right now my system is completely down 
Thanks!
Is your problem in appdata directory? Run command to find out what is your biggest folder is (ask ubuntu):
du -ah --max-depth=1 /mnt/ncdata | sort -hr
than you can check what is the biggest folder under the biggest folder and decide what to do next.
@gas85, Thanks for your help! I was about to give up. The output from the command is:
ncadmin@cloud:~$ sudo du -ah --max-depth=1 /mnt/ncdata | sort -hr
[sudo] password for ncadmin:

From what i know, I don’t see any problems with space. I am also now getting this error after logging in:
Internal Server Error
The server was unable to complete your request.
If this happens again, please send the technical details below to the server administrator.
More details can be found in the server log.

Ugh!! So frustrating!
Update
I’m getting cert errors, due to network connection problems over port 80. Should be getting fixed very soon.
File sync is oddly working fine
Thats funny, because your partition has no space left (100% being used):
I believe that this user (dtorres) has used most of your space.
Also appdata looks a little bit big. I bet you have previews enabled and if you check inside of appdata folder preview will be the biggest one. Example of command under appdata folder:
du -ah --max-depth=1 . | sort -hr
27G ./preview
27G .
2.9M ./js
1.4M ./appstore
704K ./css
664K ./avatar
228K ./theming
204K ./dav-photocache
124K ./identityproof
20K ./external
8.0K ./richdocuments
As you can see my previews folder is huge, but this does not disturbs me → Previews / data size
OK here is the before:
ncadmin@cloud:~$ sudo du -ah --max-depth=1 /mnt/ncdata | sort -hr
[sudo] password for ncadmin:
2.8G /mnt/ncdata
2.7G /mnt/ncdata/dtorres
129M /mnt/ncdata/appdata_ocm2710gjvgh
11M /mnt/ncdata/ncadmin
11M /mnt/ncdata/jtorres
11M /mnt/ncdata/datorres
213K /mnt/ncdata/files_external
65K /mnt/ncdata/nextcloud.log
4.5K /mnt/ncdata/updater.log

I am very new to NextCloud and Linux in general. I edited the config.php file, added:
'enable_previews' => true,
'enabledPreviewProviders' =>
array (
0 => 'OC\\Preview\\PNG',
1 => 'OC\\Preview\\JPEG',
2 => 'OC\\Preview\\GIF',
3 => 'OC\\Preview\\BMP',
4 => 'OC\\Preview\\XBitmap',
5 => 'OC\\Preview\\Movie',
6 => 'OC\\Preview\\PDF',
7 => 'OC\\Preview\\MP3',
8 => 'OC\\Preview\\TXT',
9 => 'OC\\Preview\\MarkDown',
),
'preview_max_x' => 1080,
'preview_max_y' => 1920,
),
);
Then ran :
sudo -u www-data /var/www/nextcloud/occ config:app:set --value=“32 64 1024” previewgenerator squareSizes
Responce was:
Config value squareSizes for app previewgenerator set to 32 64 1024
sudo -u www-data /var/www/nextcloud/occ config:app:set --value=“64 128 1024” previewgenerator widthSizes
Responce was
Config value widthSizes for app previewgenerator set to 64 128 1024
sudo -u www-data /var/www/nextcloud/occ config:app:set --value=“64 256 1024” previewgenerator heightSizes
Responce was
Config value heightSizes for app previewgenerator set to 64 256 1024
Here is after deleting all my data and emptying the trash bin:
ncadmin@cloud:~$ sudo du -ah --max-depth=1 /mnt/ncdata | sort -hr
160M /mnt/ncdata
129M /mnt/ncdata/appdata_ocm2710gjvgh

Another view is:

Space seems to no longer be an issue. I still problems with my Cert but i’ll open a new thread on that.
Thanks for all the help!!

I can no longer login with out getting the, Internal Server Error, message. How is it possible the ncdata partition is shrinking?
Any guidance would be greatly appreciated. Thanks again!
Using the preview generator app will fill your disk if not setup properly. Hence there is a script for it in the VM that can be found here.
@enoch85 Thanks for the script. I ran it till successful but this did not address my issue. As seen below the appdata folder is a good size. I can no longer login with out getting the, Internal Server Error, message. How is it possible the ncdata partition is shrinking?
