Subject: [pve-devel] [PATCH v2 storage 1/6] diskmanage: add change_parttype and is_partition helpers
Date: Wed, 6 Oct 2021 11:18:41 +0200 [thread overview]
Message-ID: <20211006091853.82237-2-f.ebner@proxmox.com> (raw)
In-Reply-To: <20211006091853.82237-1-f.ebner@proxmox.com>
For change_parttype, only GPT-partitioned disks are supported, as I
didn't see an option for sgdisk to make it also work with
MBR-partitioned disks. And while sfdisk could be used instead (or
additionally) it would be a new dependency, and AFAICS require some
conversion of partition type GUIDs to MBR types on our part.
Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>

Changes from v1:
* Add is_partition helper here, because it is used in the next
patch.
