Subject: [pve-devel] [PATCH storage] base plugin: do not decode the empty string
Date: Mon, 2 Sep 2024 14:47:45 +0200 [thread overview]
Message-ID: <20240902124745.77160-1-m.sandoval@proxmox.com> (raw)
If the json was empty, for example if the qemu-img command times out, a
message
warn "could not parse qemu-img info command output for '$filename' - $err\n";
would have been printed.
This message could lead one to think the issue lies in the contents of
the json, even if the previous warning said that there was a timeout.
