Make Ubuntu VM NVMe storage mounting more robust
I experience periodically that, when I start a storage-optimized Ubuntu VM (size L32s), the NVMe disk is not mounted. When I try `sudo mount /mnt`, I get: `mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.` and no obvious way to fix this. Other times, the machine starts and the disk is mounted fine. No obvious pattern. Please make mounting more robust.
