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:

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?
