Sometimes this happens when your VPS is powered off abruptly, or when a piece of software or hardware malfunctions suddenly.

The success of your recovery operations comes down to a number of factors, such as how quickly the filesystem noticed the corruption, how widespread the issue was, and what files were affected. That being said, in many cases, fsck recovery is successful and you can go back to using your server without too much of a headache.

Alternate Method If your droplet is not accessible via ssh you can still boot your droplet to single user mode using this alternate method. When you see the line: First, in the control panel click on the power cycle button to reboot your droplet.

Often, these are files that you had deleted anyways, but were still being used when the system crashed. Once the reboot has completed you will find yourself at a very minimal shell similar to the one shown below: If your filesystem is noticeably broken still, or if the boot fails when changing back to multi-user mode, your best option may be to use a recovery ISO to recover any needed files.

After a few seconds you should see a screen like this:FreeBSD includes a filesystem checking utility called fsck that can be used to recover your system in cases of corruption.
