Database Crashed

Hi,

When I tried to open my Nextcloud in a web browser suddenly did not work and when i tried to log in to MySQL it is throwing errors and when I am checking occ status it is also throwing an error I cant find where the issues are?

Steps to replicate it:

  1. I cannot open MySQL login.
  2. I cannot able to check the occ status
  3. i cannot able to login Nextcloud browser login page

Did you try to repair the tables? The oc_file_locks can be emptied, that is just for locking files during they are changed. If everything runs through your database instead of a dedicated cache, it can create an important load and lead to locked files:

Could be that it is too much for your database and a redis cache could solve your problem.

for me this error

sounds like a root cause. If the DB can’t access required files no wonder it crashes… take look here:

This is resolved after dropping the oc_filecache table but I’m unable to view the files which I have in nextcloud.

I have decrypted all files but still i cant able to open any of miles showing file is damaged or corrupted or unsupported format

Also when I download those files it shows an Internal server error.

You shouldn’t do that. Especially with encryption since the files are signed with information from this table.

You can restore single files with password and the keyfile only. There were some topics about this here in the forum or on github.
With a current backup, it’s perhaps the easiest, to restore the backup and just pick and restore single files that were changed since the backup. Then all the client sync and apps are working.

Sorry for the information which i have given wrongly i have dropped the table of oc_filelocks.

As I am having the master keys for private and public and each individual user key for files i have tried with occ encryption:decrypt --all username but still the issue is not resolved.

The error inidicated database server detected corruption of specific database table on startup… but there might be more which are not detected now… your tries on the application side don address the underlying issue… most likely the apparmor caused database corruption and you need to recover… I would recommend you to restore last known good backup and try again.
