Subject: [pve-devel] [PATCH container] fix #5761: add the "discard" mount option
Date: Wed, 9 Oct 2024 16:22:00 +0200 [thread overview]
Message-ID: <20241009142200.130318-1-f.schauer@proxmox.com> (raw)
Introduce the "discard" mount option for rootfs and mount points. This
ensures that unused container volume blocks are discarded from the
underlying storage backend when deleting files within the container.
