[pve-devel] [PATCH-SERIES storage/widget-toolkit/manager] Add wipe disk api call and button

[pve-devel] [PATCH-SERIES storage/widget-toolkit/manager] Add wipe disk api call and button

[Fabian Ebner]

so admins wipe disks that are not actually used, but contain left-overs.

The last patch needs dependency bumps for pve-storage and
proxmox-widget-toolkit.

storage:

Fabian Ebner (5):
  diskmanage: add wipe_blockdev method
  diskmanage: factor out mounted_blockdevs helper
  diskmanage: add is_mounted method
  diskmanage: add has_holder method
  api: add wipedisk call

[pve-devel] [PATCH storage 01/11] diskmanage: add wipe_blockdev method

[Fabian Ebner]

based on the wipe_disks method from pve-manager's Ceph/Tools.pm with the
following main differences:
    * use wipefs to wipe labels first (to avoid sgdisk complaining about the
      backed up GPT structure on a subsequent GPT initialization)
    * only take one device as an argument
    * do not use an absolute path for 'dd'
    * die if one of the command fails

The wipefs command makes checks and complains about e.g. mounted or active
devices. One could supply --force to wipefs, but in many such situations it
does not work as expected, because the device would still be detected as in-use
afterwards, and further manaual steps would be needed.

[pve-devel] [PATCH storage 05/11] api: add wipedisk call

[Fabian Ebner]

Try to detect active mounts and holders early, because it's cheap. The wipefs
command in the worker will detect even more situations where wiping alone is
not enough for the device to show up as unused, or could otherwise be
problematic.

applied the storage part, with a followup to add the single partitions to the wipefs
command to ensure that really all FS signatures are gone, else, if one creates a
similar partition layout later a mkfs. call may complain about potential existing FS.

applied the remaining patches.

Next things to do:

* enabled wiping for partitions
* hint that disks recognized as OSDs should use the OSD destroy dialogue if possible (i.e., if
  that disk is actually an OSD in the current cluster and all is still healthy enough for that)
* I'd change the top bar in general more like the OSD tree one, i.e., only reload left and the
  wipe/smart/init GPT buttons on the right with the selected disk text prefixed
* The confirm dialogue feels like it could get still some improvement about how to convey
  what will be destroyed more nicely, but as I do not have concrete proposals I just mention
  it for the sake of it, maybe someone else has better ideas.
