Subject: Re: Unable to mount degraded RAID5
Date: Sun, 10 Jul 2016 09:01:56 +0200 [thread overview]
Message-ID: <31d22f36-b97a-c150-3125-576a830e08c1@gmail.com> (raw)
In-Reply-To: <CAJCQCtSA9TXO5dEZ-77hoFnc3VAa+81KRoEx9CoJhfStvW3O0A@mail.gmail.com>
After every step, I tried mount fs with ro, ro,recovery and
ro,degraded,recovery. If failed, I moved to next step.
