Description of problem:
Attempt to request custom disk partition on the boot disk fails.
From node's console it reports issue mounting /sysroot:
Error: system has 0 devices with a filesystem labeled 'boot': [] coreos-ignition-unique-boot.service: Main process exited, code=exited, status=1/Failure
Version-Release number of selected component (if applicable):
4.19.0-ec.4
How reproducible:
100%
Steps to Reproduce:
1. Request a custom disk partition for `var` directory on the same disk requested by `rootDeviceHints` in the ZTP site-config
automatedCleaningMode: metadata nodeLabels: node-role.kubernetes.io/standard: '' rootDeviceHints: deviceName: /dev/disk/by-path/pci-0000:5c:00.0-sas-0x58ce38ee220a82fe-lun-0
2. Specify ignitionCOnfigOverride
ignitionConfigOverride: '{"ignition": {"version": "3.2.0"},"storage": {"disks": [{"device": "/dev/disk/by-path/pci-0000:5c:00.0-sas-0x58ce38ee220a82fe-lun-0","partitions": [{"label": "var","number": 5,"sizeMiB": 0,"startMiB": 307201,"wipePartitionEntry": true}],"wipeTable": true}],"filesystems": [{"device": "/dev/disk/by-partlabel/var","format": "xfs","mountOptions": ["defaults","prjquota"],"path": "/var","wipeFilesystem": true}]},"systemd": {"units": [{"contents": "# Generated by Butane\n[Unit]\nRequires=systemd-fsck@dev-disk-by\\x2dpartlabel-var.service\nAfter=systemd-fsck@dev-disk-by\\x2dpartlabel-var.service\n\n[Mount]\nWhere=/var\nWhat=/dev/disk/by-partlabel/var\nType=xfs\nOptions=defaults,prjquota\n\n[Install]\nRequiredBy=local-fs.target","enabled": true,"name": "var.mount"}]}}'
3. Start deployment
Actual results:
Deployment fails as nodes fail to boot and end up in emergency shell
Expected results:
Deployment succeeds
Additional info:
When requesting portion on other than "boot" disk it works without issues:
