Hi,

Run this:

1. wget https://raw.githubusercontent.com/nextcloud/vm/main/disk/zfs-prune-snapshots.sh
2. sudo bash zfs-prune-snapshots.sh 1s
3. sudo apt purge zfs-auto-snapshot (if you don't want it anymore)

[FrankHae]

Thanks. Now
ncdata 1K-blocks: 40086144 used: 35741056. avail: 4345088. Use 90%. ??
90% use, I think this value is still far too high...

Userconfigurtion?
This system is original from Hansson IT and is only updated by the automated scripts from Hansson IT.
I have not made a single change and still have a lot of problems.

[enoch85]

Well, there are pretty many factors which could play a role here...

Another guess is that your trashbin are full, try to delete that and cleanup: wget https://raw.githubusercontent.com/nextcloud/vm/main/disk/prune_zfs_snaphots.sh && sudo bash prune_zfs_snaphots.sh

Did it work?

[FrankHae]

Yes this did work:

There are actually only 2 User.....
The trashes are empty
There are ONLY files (1 User) in external storage.
The other user has NOT any data...

EDIT:
I have logged the last user out of external storage. Now there is no more external storage and no more local storage... 2 users, no local data and no external data. The recycle bin is empty, but the storage space is still 96% full.

[enoch85]

External storage doesn't affect the local storage since it resides on a remote location.

I suggest you book support for us to have a look: https://shop.hanssonit.se/product/premium-support-per-30-minutes/

I guess you actually use that much data, or something is very wrong.

Have you tried a reboot?

External storage doesn't affect the local storage since it resides on a remote location.

Yes I know, but every attempt counts....
Every 30 minutes I get this

I think that's a good (probably the only) idea.

I guess you actually use that much data, or something is very wrong.

I have no idea. Only 2 users, no data (data temporarily stored elsewhere), recycle bin empty,

Have you tried a reboot?

Of course, several times

The installation ran smoothly for several months. Only the automated updates were installed

This error messages have only been present since the last update.

• The .htaccess file does not work...
• The server does not have a configured start time for the maintenance window...

This message was already there from the beginning.:

• The PHP module “imagick” is not activated

[enoch85]

Can we close this?
