Hi Andreas
Thanks for the prompt response,
Yes I did not use a partition table. I have always in the past used
partitions but recently noticed a trend to use the device, wont do
that again.
I am really not sure what wrote those partitions there. I only see
free space in them if I check with fdisk.
I am sure it was metadata version 1.2
I will attempt to recover using the overlay, will post my results.
Good call. The whole point of overlays is to enable you to write-protect
the physical disks. That means (of course) that you can't make matters
worse. That's always the worry - that an attempt at a fix will damage
the content of the disks and make a recovery harder/impossible.
Thanks again for your help.
A little more (hopefully) help - on the wiki the last entry in the "When
things go wrogn" section is about recovering a trashed array. As it
says, it's a work in progress, but it gives you various hints about how
to search the disk for clues as to where your data is, and hence what
all those things like offsets are.
Have you ever added disks to your array? Rebuilt and changed its
configuration? This can mess about with the superblock values changing
them from the defaults. This is information the list will want.
If you have trouble getting overlays to work, search for clues like this
on your list and get back here for help. ON NO ACCOUNT do anything that
will actually write to your disks unless you are absolutely confident
that you've found the correct magic incantation.
There are plenty of people here who will help you get your data back -
and they've got a good track record! Unfortunately, I'm "learning by
documenting" so I'm quite happy to give you hints and guidance, but I
can't say for certain what is likely to work.
Cheers,
Wol
