On a linux system we are unable to run ghost

Issue/Introduction

Unable to run ghost on a Linux machine

Environment

GSS 3.x

DS 8.x

Cause

Using non-supported drives

 

If you run lsblk and the drive is listed, ( in this case the drive in nvme0n1 )

but if run ./gdisk64 and the drive is not listed then running ghost to take an image will not work

Gdisk is unable to see the NVMe m2 drive

 

Resolution

Use tar commands to image the drive.  Use the provide script file and add it to the LinuxPE environment within bootwiz ( Right click on the configuration name > add > file and locate the gssbackup.sh file )

Also if you want the script to start automatically add: ./gssbackup.sh  to the startup.rc file in the configuration

Example backup script to use: (also attached at bottom of this document )
NOTE: it's required to save this file as UNIX file type, not windows.  Best Practice is to create this file on UNIX.

Additional Information

gssbackup zip file attached to this case includes a .sh file that has been saved on a Unix system (by running dos2unix).  Only edit this file inside Unix, if editing is required.  Saving this file in Windows will ruin the Linux formatting.
