Ah yes, I remember have seen this before.

Need to check whether it happens with "occ files:scan --all". If yes, does it abort scanning or continues ?
If it aborts, then that's bad => high.
If it ignores it, not too bad => medium

Setting to high for now to try it out.

Yes, it was happening with --all in the first place.

If yes, does it abort scanning or continues ?

Don't know. It happend on the last projected user...

Not too bad, I just tried the following:

1. Create a user "user1" in the web UI but DO NOT login with that user
2. Create a user "user2"
3. Login as "user2" to init home
4. run occ files:scan --all

petry:/srv/www/htdocs/owncloud # sudo -uwwwrun ./occ files:scan --all -vvv
The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see http://php.net/manual/en/book.pcntl.php

Scanning files for 3 users

Starting scan for user 1 out of 3 (admin)
        Folder /admin/
        Folder /admin/files
        File   /admin/files/welcome.txt
        Folder /admin/files/test
        Folder /admin/files/test2
        Folder /admin/cache
        Folder /admin/thumbnails
        Folder /admin/thumbnails/3
        File   /admin/thumbnails/3/2048-2048-max.png
        File   /admin/thumbnails/3/32-32.png

Starting scan for user 2 out of 3 (user1)
Home storage for user user1 not writable
Make sure you're running the scan command only as the user the web server runs as

Starting scan for user 3 out of 3 (user2)
        Folder /user2/
        Folder /user2/cache
        Folder /user2/files
        File   /user2/files/welcome.txt
        Folder /user2/thumbnails
        Folder /user2/thumbnails/16
        File   /user2/thumbnails/16/2048-2048-max.png
        File   /user2/thumbnails/16/32-32.png

As we can see, the home of "user1" is skipped but scanning continues.
Downgrading to sev3-medium as it's not too bad.

Then the question is what to do with such storages. Since the user did not log in they don't have a skeleton yet.

Should we trigger skeleton creation at this time ? (might be slow with many users)
Or should we just adjust the error message to say "User hasn't logged in yet, cannot scan" ?

@icewind1991 @mmattel didn't we fix that recently ?
