Help mounting SHR under ubuntu

[Asgard]

Hello, I pulled out of my nas (Synology) disk, to recover a deleted folder.

I got the /dev/md2 and /dev/md3 devices in raid0 started.

 

cat /proc/mdstat
md3 : active raid1 sda6[1]
     976742784 blocks super 1.2 [2/1] [_U]

md2 : active raid1 sdb5[2]
     1948779648 blocks super 1.2 [2/1] [_U]

unused devices: 

 

So now I have two /dev/md2 and /dev/md3 that need to be in LVM.

So I did pvscan

Couldn't find device with uuid 8s9LfU-Egt2-sbtJ-1zkH-ewqb-LjRT-xZ2RC2.
 PV unknown device   VG vg1000   lvm2 [1.81 TiB / 0    free]
 PV /dev/md3         VG vg1000   lvm2 [931.49 GiB / 0    free]
 Total: 2 [2.72 TiB] / in use: 2 [2.72 TiB] / in no VG: 0 [0   ]

 

And it just cannot find the device with that uuid, but its right there:

blkid:

It worked in synology box.

Disk /dev/md3 doesn't contain a valid partition table

 

So fdisk -l shows kinda akward /dev/md2p1, maybe thats the problem. How could I get the LVM working in ubuntu that I could use extundelete?

install mdadm and lvm2

 

run the command

 

mdadm –Asf

vgchange -ay

I cannot try the commands now, but when I tried these commands then the output was something like: first command worked and found and configured raid, but with one disk. The other command, the lvm command outputted that cannot find uuid.
