Subject: [pve-devel] [PATCH v2 storage 2/6] diskmanage: wipe blockdev: also change partition type
Date: Wed, 6 Oct 2021 11:18:42 +0200 [thread overview]
Message-ID: <20211006091853.82237-3-f.ebner@proxmox.com> (raw)
In-Reply-To: <20211006091853.82237-1-f.ebner@proxmox.com>
when called with a partition. Since get_disks uses the partition type
(among other things) to detect LVM and ZFS volumes, such volumes would
still be seen as in-use after wiping. Thus, also change the partition
type and simply use 0x83 "Linux filesystem".
