[pve-devel] [PATCH installer v3 0/4] add check/rename for already-existing ZFS rpool

[Christoph Heiss]

Pretty straight forward overall, implements a check for an existing
`rpool` on the system and ask the user whether they would like to rename
it, much in the same way as it works for VGs already.

Without this, the installer would silently create a second (and thus
conflicting) `rpool` and cause a boot failure after the installation,
since it does not know which pool to import exactly.

v1: https://lists.proxmox.com/pipermail/pve-devel/2024-May/063874.html
v2: https://lists.proxmox.com/pipermail/pve-devel/2024-July/064619.html

Notable changes v2 -> v3:
  * make low-level option lvm_auto_rename more generic
  * skip rename prompt in auto-install mode

Notable changes v1 -> v2:
  * incorporated Aarons suggestions from v1
  * rewrote tests to use a pre-defined input instead
  * moved pool renaming to own subroutine
  * documented all new subroutines
  * split out tests into own patch

Christoph Heiss (4):
  test: add test cases for new zfs module
  low-level: install: check for already-existing `rpool` on install
  install: config: rename option lvm_auto_rename ->
    existing_storage_auto_rename
  low-level: install: automatically rename existing rpools on
    auto-installs
