Nextcloud problems after update

Support
#1

NethServer Version: 7.9.2009
Module: nextcloud
Hello guys,
I have a problem in nextcloud, since the last update nectcloud stopped working, I can only see 4 files in the web interface with no folders and I can’t create anything more.
Here the logs :
Error: disk_free_space(): No such file or directory at /usr/share/nextcloud/lib/private/Files/Storage/Local.php#381

Error: fopen(/var/lib/nethserver/nextcloud/7a24f9ae-8122-1038-9de4-8fb1afc488fc/files/Photos/Readme.md): failed to open stream: No such file or directory at /usr/share/nextcloud/lib/private/Files/Storage/Local.php#363

disk full? I still have about 200GB free…
anyone can help me ?

Nextcloud problem after upgrade
#3

sorry for the double posting, I cannot delete the message

#4

Probably useless hint but… would you please start from console signal-event nethserver-nextcloud-update and try again?

#5

everything is useful when you can learn a bit more, but here’s the log after launching the command

and in the attached image you can see what’s the problem, there also was an external storage configured (/var/lib/nethserver/ibay/shared/) not visible now

#6

is this path available to your server currently? (bold added by me)
Is it mounted in R/W mode?

#7

the path is in the same server, is the local folder shared with samba to internal network clients

#8

the folder is owned by nobody:root

#9

And this permission IMVHO should not be correct…
image
But I am not linux-skilled to suggest the correct chown instruction

#10

@pike

Hi

The correct syntax for changing the permissions (actually here only owner, not permissions) in NethServer would be:

chown -R root.root /var/lib/nethserver/ibay/shared/

chown changes the owner
-R is recursive, including subfolders
root.root = owner.group
path is the valid path…

My 2 cents
Andy

#11

Thanks for the contribution, @Andy_Wismer, I hope that Gatto will use it and… this would help to solve the issue.

i think it is not a folder permission problem, that folder inherit owner from samba sharing in local ldap mode. Also apache give me no errors when I connect it as external storage folder to nextcloud. This configuration ran for many months before the crash, I suspect there was a hardware reset of the server, maybe a power fault that corrupt some file.
Can I completely purge and reinstall nextcloud without touching db, users and files?

#13

then scrub your logs, messages for starters but not only…

#14

no errors in logs but when I try to run
sudo -u apache scl enable rh-php73 – php /usr/share/nextcloud/occ maintenance:mode-on the result is :
An unhandled exception has been thrown:
OCP\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)
if I run instead
sudo -u apache scl enable rh-php72 – php /usr/share/nextcloud/occ maintenance:mode-on
This version of Nextcloud requires at least PHP 7.3
You are currently running 7.2.24. Please update your PHP version
could it be a wrong php version? how can I upgrade it?

#15

You can run occ directly without choosing the php version, as on nethserver there is an occ wrapper file.

Check rh-php73-php-pecl-apcu package is installed.
Maybe nextcloud’s config.php file is worth a look.

Probably an upstream bug (similar bug was reported on nextcloud github issue tracker).

For peace of mind you can check your user files are not gone:

/var/lib/nethserver/nextcloud/*

same with the external share /var/lib/nethserver/ibay/shared/

#16

I ran into this on my RPI I managed to fix it NextCloud Update how to Raspberry Pi - #2 by Shane_Treweek

#17

tried your solution but no luck. I’m now running
sudo -u apache scl enable rh-php73 – php -dmemory_limit=512M -d apc.enable_cli=1 /usr/share/nextcloud/occ files:scan --all
to see if there are any corrupted files or folder.
I got two warnings like :
Starting scan for user 4 out of 8 (591c04f0-8122-1038-9de3-8fb1afc488fc)
Home storage for user 591c04f0-8122-1038-9de3-8fb1afc488fc not writable
but if I run ls -l on 591c04f0-8122-1038-9de3-8fb1afc488fc
I get
drwxr-xr-x 2 apache apache 6 May 31 2021 cache
drwxr-xr-x 5 apache apache 47 Jul 15 2021 files_trashbin
drwxr-xr-x 3 apache apache 20 Aug 2 2021 files_versions
drwxr-xr-x 2 apache apache 6 Jul 12 22:18 uploads
this server is driving me mad…

#18

Can you restore a pre-package upgrade backup?

#19

Well, I think is the last chance we have… I’m going to do it…

#20

A skilled/experienced sysadmin with centos and nextcloud competence maybe can find the real hiccup browsing into logs of OS and nextcloud.
A better and more wise sysadmin that i am now. Sometimes you hit the wall of your lack of knowledge. Will power, time and patience (adding also reading and scheduling steps) are great tools to learn something new.
