Subject: [PATCH 14/22] tests: test self-cure of parallels image with duplicated clusters
Date: Mon, 18 Sep 2023 20:00:52 +0200 [thread overview]
Message-ID: <20230918180100.524843-16-den@openvz.org> (raw)
In-Reply-To: <20230918180100.524843-1-den@openvz.org>
The test is quite similar with the original one for duplicated clusters.
There is the only difference in the operation which should fix the
image.
