In Windows a new line, is a CR (carriage return) followed by LF (line feed). In Linux, it’s just LF. If you bring over a text file from Windows to Linux, sometimes you’ll end up with a file with a bunch of ^M at the end of each line, which will breaks a lot of things. To fix, just run dos2unix.

Here’s how to identify your disks on the system to cross check with GCP Dashboard.
ls -l /dev/disk/by-id |
ls -l /dev/disk/by-id
Result:
[root@servername ~]# ls -l /dev/disk/by-id total 0 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 google-boot -> ../../sda lrwxrwxrwx. 1 root root 10 Sep 15 05:30 google-boot-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 google-persistent-disk-1 -> ../../sdb lrwxrwxrwx. 1 root root 9 Sep 15 05:30 scsi-0Google_PersistentDisk_boot -> ../../sda lrwxrwxrwx. 1 root root 10 Sep 15 05:30 scsi-0Google_PersistentDisk_boot-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 scsi-0Google_PersistentDisk_persistent-disk-1 -> ../../sdb |

Here’s how to display a list the disks attached to an instance.
