Check NixOS configurations / eval-hosts (push) Failing after 9m44s
/dev/sda and /dev/sdb are assigned by the OS based on Proxmox disk-add
order, which is not consistent across VMs. Use the SCSI controller path
instead — drive-scsi1 is always the dedicated data disk on all HA nodes
regardless of which sda/sdb it gets assigned to.
variables.nix: replace per-node haServer{1,2}DrbdDisk with a single
haServerDrbdDisk using /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi1.
cluster-config.nix: revert to shared volume block (per-node block was
needed for /dev/sd* but the by-id path is identical on both nodes).
cluster-init.sh:
- single DRBD_DISK variable (matching haServerDrbdDisk)
- robust /etc/drbd.conf patch: NixOS manages this file as a symlink to
a read-only Nix store path; cp --remove-destination breaks the symlink
before sed -i so the edit actually takes effect
- scp helper script to NODE2 rather than bash -c over SSH to avoid
quoting complexity
