Subject: grub-probe: "found two disks with the index 3 for RAID md2" after changing superblock 0.9 to 1.0
Date: Mon, 15 Sep 2014 06:47:41 +0000	[thread overview]
Message-ID: <20140915064741.GH11855@bitfolk.com> (raw)

Hi,

During the process of shrinking the number of devices in a raid-10
array from 6 down to 4¹, I needed to upgrade the superblock from 0.9
to 1.0.

Now, when I run grub-probe on that host it gives me complaints like
this:

    error: found two disks with the index 3 for RAID md2.
    error: superfluous RAID member (6 found).

(many times over)

Searching around I learn that it may be because grub looks at the
end of the disk and finds an md superblock but cannot tell if it is
for the entire disk or for the final partition on the disk:

    http://savannah.gnu.org/bugs/index.php?34250

In my case, I have four disks sda to sdd all of which have three
partitions on them, and md2 is composed of the third (last)
partition.

    $ cat /proc/mdstat 
    Personalities : [raid1] [raid10] 
    md2 : active raid10 sdd3[0] sdb3[3] sdc3[4] sda3[5]
          618726528 blocks super 1.0 64K chunks 2 near-copies [4/4] [UUUU]

    md1 : active raid10 sda2[0] sdd2[3] sdc2[2] sdb2[1]
          5874688 blocks super 1.2 512K chunks 2 near-copies [4/4] [UUUU]

    md0 : active raid1 sdd1[0] sdc1[3] sdb1[2] sda1[1]
          256896 blocks [4/4] [UUUU]

    unused devices: <none>

The thing is, that bug report is quite old and is marked closed, and
also states:

    "The problem is that 0.9x metadata block doesn't have enough
    info to check it. With 1.x we have no such problem."

Of course, it *is* 1.x superblock. Did the poster actually mean to
say that they have no problem with v1.1 and v1.2 (because they are
located at or near the beginning of the device, not at the end)?

The host is Debian wheezy with grub-pc package version
1.99-27+deb7u2 so if that bug is closed due to a fix, I would expect
to have it by now.

There is also a Debian bug bearing some similarity, and that is also
marked fixed upstream and references the above Gnu bug report.

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620390

The host still boots but that may be because md2 is not involved in
booting anyway.

Do other people experience this?

Is it unavoidable with v1.0 superblock?

If so, is there any way to convert to 1.1 or 1.2 without recreating
the array?

Verbose grub-probe output is appended.

Cheers,
Andy
