fsck-on-nextboot

Warning

You must only use this command when recommended by Sophos Support. It helps resolve /sig, /conf, or /var partition mount errors on startup. If the firewall hardware or SSD isn't healthy, it can damage the file system.

Check the file system integrity of all the partitions. Turning this option on forcefully checks the file system integrity on the next device restart. This check is automatically turned on if the device goes into failsafe mode. The device can go into failsafe mode for the following reasons:

  • Unable to start config, report, or signature database.
  • Unable to apply migration.
  • Unable to find the deployment mode.

Command

system fsck-on-nextboot

Syntax

system fsck-on-nextboot
[on |off | show]

Options

[on |off | show]

Turn integrity checking on or off for the next restart or show the current configuration. Default: off.
