[SOLVED] Update to 21.0.2 fails on files backup

Dear Community,

I get an issue when trying t update from 21.0.1 to 21.0.2 on my Debian 10 machine (Dell R240, 16GB RAM, 3x1TB hardware RAID5, Apache 2.4.38, PHP 7.3.27):

  • Web updater gets stuck at step 4 “Create backup” with no error message

  • CLI updater (sudo -u nextcloud php updater.phar) returns

    Check for expected files …sda4: write failed, user block limit reached.
    PHP Warning: file_put_contents(): Only 0 of 26 bytes written, possibly out of free disk space in phar:///home/nextcloud/public_html/updater/updater.phar/lib/Updater.php on line 1008
    [✘] Check for expected files failed
    Could not write to .step
    although 1.8TB is avaliable on sda4!

Did anyone already encounter this? Could this be linked to the RAID configuration on my machine?

Thanks in advance for any help!

SOLVED: there was a curious disk quota that prevented files creation… :thinking:
I now have another error (HTTP 500) while downloading the update and will investigate on the server configuration.
