Openshift nodes with multipath attached root disk

Issue

• I've migrated some nodes from M4 AWS instances to M5. Since this change, some of the nodes have a multipath attached root disk, which causes the Grub install to fail.

  • Single-path device:

    nvme0n1       259:0    0  450G  0 disk 
    ├─nvme0n1p1   259:1    0  512K  0 part 
    ├─nvme0n1p2   259:2    0   20G  0 part /
    

  • Multipath device:

    nvme0n1         259:0    0  450G  0 disk  
    └─mpatha        253:0    0  450G  0 mpath 
      ├─mpatha1     253:1    0  512K  0 part  
      ├─mpatha2     253:2    0   20G  0 part  /
