[fvdw]

for me it is bedtime :z)

[Jocko]

So that means yesterday we work on the sane disk :dry

but sdx8 and sdx9 does not contain the data.

For me it is too late now


So see you later this WE

To recover your data:

As you have an Ubuntu.
-plug on it the sane disk
-on a terminal window, assemble partition 2 like I posted previously (with one component only)
- mount the raid device and you should see a folder shares where are your data

[manelppa]

thank you both of you fvdw and Jocko. I understand it's late. It's late for me too. Yesterday I went bed at 4:22 because I wanted to understand...

Cheers

[Jocko]

so
:z)

[manelppa]

Dear Jocko,
I will need your help to assemble the RAID as you suggested. I've many errors when I try your cmd

Code: Select all

mdadm --zero-superblock /dev/sdb8 => Unrecognised md component device - /dev/sdb8
-- same for sdb9
mdadm --assemble /dev/md1 /dev/sda8 --run => mdadm: no recogniseable superblock on /dev/sdb8
mdadm: /dev/sdb8 has no superblock - assembly aborted

cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]

Hi manelppa

Be careful, with your 2big2 and with fvdw-sl console, currently sdb is the safe disk and sda is the new disk

So on any partition from sda there is no super block as long as you do not add them on existings raid!
And you delete super block (zero-superblock) on sdbx and you destroy the raid on sdbx!(but with a raid1 data are still here :whistle )

Note: on sda8 or 9 it does not matter but DO NOT DO this command on sdb2!


So please explain what commands did you run on the raid component.
(it was bed time yesterday night!)

[manelppa]

Hello Jocko,
I understand : do not touch SDB 2... I know and I won't make mistake.

the cmd I run yesteday for which I got the error message are the same I sent late yesteray.

From this point, I don't know what to do. Just ask me to post few results from check, maybe you'll have an idea of what is going on.

Kind regards,

[manelppa]

Probably stupid but : what happen if I recreate the RAID partition (except sdb2) ?
Is it a risk to delete the partition 5, 7, 8 & 9 and recreate using fdisk, then affect the type and copy the *.gz files without touching the SDB2

I've tried to mount the sdb2 partition in /mnt, but I get an error message : "sdb2 already mounted or /mnt busy"

[Jocko]

Well, I think first it would be better to backup data from your sane disk.

It is why posted yesterday

As you have an Ubuntu.
-plug on it the sane disk
-on a terminal window, assemble partition 2 like I posted previously (with one component only)
- mount the raid device and you should see a folder shares where are your data
