 # Troubleshoot Linux VM boot issues due to fstab errors
@@ -112,13 +113,17 @@ Azure Linux Auto Repair (ALAR) scripts are part of the VM repair extension descr
 The ALAR scripts use the repair extension `repair-button` to fix fstab issues by specifying `--button-command fstab`. This parameter triggers the automated recovery. Implement the following steps to automate fstab errors via the offline ALAR approach:
 
 ```azurecli-interactive
-az vm repair repair-button --button-command fstab --verbose rgtest --name vmtest
+az extension add -n vm-repair
+az extension update -n vm-repair
+az vm repair repair-button --button-command 'fstab' --verbose $RGNAME --name $VMNAME
 ```

-> - Replace the resource group name `rgtest` and VM name `vmtest` accordingly.
-> - The repair VM script, in conjunction with the ALAR script, will temporarily create a resource group, a repair VM, and a copy of the affected VM's OS disk. It backs up the original **/etc/fstab** file and modifies it by removing or commenting out data file system entries that aren't required to boot the system.
-> - After the OS starts successfully, review and edit the **/etc/fstab** file to fix any errors that might have prevented a proper reboot. Finally, the `repair-button` script will automatically delete the resource group containing the repair VM.
