Subject: [pbs-devel] [PATCH proxmox-backup v6 21/21] GC: clean up bad chunks from the filesystem only
Date: Fri, 14 Nov 2025 14:19:01 +0100 [thread overview]
Message-ID: <20251114131901.441650-22-c.ebner@proxmox.com> (raw)
In-Reply-To: <20251114131901.441650-1-c.ebner@proxmox.com>
Bad chunks are not present in the in-memory LRU cache, so only clean
up the bad chunk file from the filesystem.
