Can you mount the boot disk as a secondary disk on another vm and check the following:

mount /dev/sdX2 /mnt/part2

then check the following
ls /mnt/part2
this should show the root file system

ls /mnt/part2/boot
should the following ( new kernel + initrd image )
grub initrd.img-4.12.14-08-petasan vmlinuz-4.12.14-08-petasan

what is the output of (if it exists)
cat /mnt/part2/boot/grub/grub.cfg

I checked upgrading a 2.1 to 2.2 as a VM in vSphere and it is working here.

The listing you posted looks good. Maybe the boot loader failed to install, can you try the following while the disk is mounted in the second VM:

mount --bind /sys /mnt/part2/sys
mount --bind /proc /mnt/part2/proc
mount --bind /dev /mnt/part2/dev

chroot /mnt/part2/ grub-install --target=i386-pc --modules="ext2 part_gpt" /dev/sdX

where sdX is the drive the failed disk is seen as in the second VM.  Does the command complete successfully  ? If so remove it from the second VM and use in the original VM as first disk ( sda ), double check the disk order.

Let me know how this goes.

Note if this is a production system, you can re-install 2.1 on a new VM os/disk and do a "Replace Management Node"  deployment if it is node 1-3, else do a Join. After deployment you can move the old OSD vmdks (if any) to the new VM and restart.

I take ubuntu live CD:

root@ubuntu-server:~# mount /dev/sda2 /mnt/part2

root@ubuntu-server:~# chroot /mnt/part2/ grub-install --target=i386-pc --modules="ext2 part_gpt" /dev/sda2

Installing for i386-pc platform

grub-install: error: cannot find a device for /boot/grub (is /dev mounted?)

 

I try the from "hirens boot cd" different linux distro and get the same error

sdX is the drive the failed disk is seen as in the second VM

enter the drive like /dev/sda /dev/sde   ...not a partition

OK

YES

root@ubuntu-server:~# mount /dev/sda2 /mnt/part2

root@ubuntu-server:~# chroot /mnt/part2/ grub-install --target=i386-pc --modules="ext2 part_gpt" /dev/sda

Installing for i386-pc platform

grub-install: error: cannot find a device for /boot/grub (is /dev mounted?)

The same error.

Sorry, my wrong mounts))

Now a have:

Installing for i386-pc platform

grub-install: warning: Your embedding area is unusually small. core.img won't fit in it..

grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.

grub-setup: error: will not proceed with blocklists.

The 386-pc by itself is not an issue,  it specifies mbr/bios partition. the error itself is strange. we also did an upgrade on vms in vSphere and they worked. can you give more detail: what version of vmware, any special disk settings that may help us reproduce this.

again if this was a production system, i suggest you re-deploy a new vm with 2.1 and do a replace management node
