We are running Fedora 24 w/ a VessRAID 1840i and we are seeing these errors from the file system:

 fdisk -l

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

Running fsck I get this:

fsck  /dev/sdc1

fsck from util-linux 2.28.2

Is there any other utility that I can run to fix this error?

Thanks so much.

Hi Rob,

You can use any 3rd party softwares to repair the File System .  Please be aware that you have to purchase it before you can repair the Volume and also check if it is compatible with your Operating System.

If you have the back up of the data, then formatting the volume and restoring it would be the easiest way to fix these issues.

Let us know if you have any questions.
