[BUG] install fails at grub2-install

[kkaempf]

Describe the bug

Fresh install on a dual-cpu, dual-ssd server. Installer chooses /dev/sdb (to my surprise) and stops after a while with

grub2-install: error: failed to get canonical path of '/run/cos/target/boot/efi'

To Reproduce
Steps to reproduce the behavior:

• boot from iso image
• accept defaults (only /dev/sdb was offered)
• wait

Expected behavior

Installation to succeed 😉

Support bundle

Environment:

• Harvester ISO version: harvester-v1.0.0-amd64.iso
• Underlying Infrastructure (e.g. Baremetal with Dell PowerEdge R630):
  2x AMD EPYC 7282 (Zen-Rome) 16-Core CPU,
  2x SSD 1,9TB SAS3, 24x7, 1 DWPD, Samsung PM1643

@kkaempf Can you change to TTY2 and capture the output of sudo lsblk and sudo blkid? Thanks!

[kkaempf]

Sorry, the system has a broken serial console and (apparently) there's no other way to access it :-(
Will retry on a similar system 🤞🏻

Turns out that the problem probably was caused by a broken /dev/sda. As the drive was replaced meanwhile, I cannot reproduce the problem.
Closing for now. Will re-open if/when new logs are available,

I had this same issue, it seems if you already have an efi partition, it doesn't wipe it out correctly and the old label remains, in my case VMWARE label still existed. after doing a zero wipe of the first gig of the drive, reinstalling worked fine and blkid shows the name of the EFI partition as COS_GRUB instead of VMWARE.....
