Subject: [pve-devel] [PATCH manager 1/3] ui: virtiofs edit: drop writeback checkbox
Date: Tue,  8 Apr 2025 17:07:13 +0200	[thread overview]
Message-ID: <20250408150715.105253-2-f.ebner@proxmox.com> (raw)
In-Reply-To: <20250408150715.105253-1-f.ebner@proxmox.com>

VirtIO-fs using writeback cache seems very broken at the moment. If a
guest accesses a file (even just using 'touch'), that the host is
currently writing, the guest can permanently end up with a truncated
version of that file. Even subsequent operations like moving the file,
will not result in the correct file being visible, but just rename the
truncated one.
