[Bug 1940723] Re: shim-signed fails to install if grub disk config is incorrect

[Marc Landtwing]

We seem to be hitting the same issue, also on Azure.

It happens when we deploy a VM from a Shared Image gallery and change
the OS disk size during deployment. We use a template spec to deploy the
VM. If we set diskSizeGB in the storageProfile, the issue appears.


mount: /var/lib/grub/esp: special device /dev/disk/by-id/scsi-14d534654202020203d0cbbcd0bb74669a97057319f6cd140-part15 does not exist.

ls -al /dev/disk/by-id/ | grep sda15
lrwxrwxrwx 1 root root  11 Sep 15 10:23 scsi-14d53465420202020ad9d668420ceb0419516df3a7418668d-part15 -> ../../sda15

I does not happen when we keep the original OS size from the image:
ls -al /dev/disk/by-id/ | grep sda15
lrwxrwxrwx 1 root root  11 Sep 14 09:04 scsi-14d534654202020203d0cbbcd0bb74669a97057319f6cd140-part15 -> ../../sda15

lrwxrwxrwx 1 root root  11 Sep 14 09:04 wwn-0x600224803d0cbbcd0bb757319f6cd140-part15 -> ../../sda15
