Resolving 'Can't Read Superblock' Error in Proxmox

Jeremy Theocharis -

The "Can't read superblock" error can occur in Linux systems due to a defective disk or power outage while significant changes to the superblock were being made. This error can cause data loss and may prevent you from accessing your files or folders. In this tutorial, we'll show you how to fix the 'Can't Read Superblock' error in Proxmox.

Instructions

  1. Press the "Enter" key to get a bash shell.
  2. If you don't get a bash shell, stop and wait for technical support.
  3. Execute the following command:
    fsck -y /dev/vda1
    (Note: Change "/dev/vda1" to whatever disk it says that it couldn't read.)

    This will attempt to restore the superblock from a backup.
  4. Reboot your system.
