The container should launch without crashing

disk I/O error

Looks like it's an error with our disk, not vaultwarden.

Are you running other applications off the drive just fine? It's not about free space, it's more likely the drive is failing, corrupting, or a bad cable.

I think you are using a shared storage like samba/cifs or nfs. For that to work you need to disable WAL. But i would suggest to use a different type of database in that case like postgresql or mariadb.

The storage folder is indeed shared using samba. You're saying that not sharing this folder will fix the issue?
