Subject: [PATCH 11/22] parallels: add test which will validate data_off fixes through repair
Date: Mon, 18 Sep 2023 20:00:49 +0200 [thread overview]
Message-ID: <20230918180100.524843-13-den@openvz.org> (raw)
In-Reply-To: <20230918180100.524843-1-den@openvz.org>
We have only check through self-repair and that proven to be not enough.
