[BUG] VMware disks not wiped by installer, fails to install

[aplace-lab]

Describe the bug

A fresh install of Harvester 1.0.0 on disks previously consumed by VMware datastores are not cleaned enough to install Harvester on.

To Reproduce
Steps to reproduce the behavior:

1. Start installing using an old VMware disk as the target device.

Expected behavior

Install completes.

Actual behavior

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

SSH into installer shows the following (note sdf1 with TYPE="VMFS_volume_member"):

Support bundle
Unavailable, install doesn't complete.

Resolution

1. SSH into the installer after configuring network.
2. Run sudo dd if=/dev/zero of=/dev/sd... bs=64M count=100 to remove the VMFS tag
3. Continue installing as normal
4. blkid now shows:

I will third this issue. I had already tried wiping signatures with wipefs -a, which did not resolve it, but zeroing the beginning sectors of the disk corrected the problem.

ermigard I just wasted 5 hours of my life on this issue :P

Heavens to betsy; ran into this same issue on Harvester v1.1.2 using a PXEBoot installation process. Had to CTRL+ALT+F2 and run dd if=/dev/zero of=/dev/sda count=10000 ... then re-run the installation process.

Sure would be nice if there was a Harvester config.yaml option to overwrite the existing drive during the installation process. 😄

Fixed with harvester/harvester-installer#660
