ISCSI lost partition

[Blisk]

Here is a scenario.
On qnap have created iscsi and connected and mounted on linux.
I have qnap ts212 with two disks, fev months ago I changed 3Tb disks to 4 Tb disks, by manual one by one. All goes well and works great

But yesterday I accidentally delete partition on iscsi disk, which was 3Tb in linux disk management.

I have no backup of iscsi or files of it.
So I tried testdisk to get parition back, but it didn't find parition, now is on deep scan.

So I tried disk from fev months ago, one was already used second was intacted so I put it in qnap and start but in section iscsi I can se error and when I connect iscsi in linux I can not mount it, because partition doesn't exist.

Is there possible to restore partition on first 3Tb disk or on second two 4Tb disks???

that old cat1 device of yours, should have plenty of options

stick any of the old disks into the nas and it should boot up (including your file based iscsi)

stick any of those disks in a linux computer and copy off the lun ..plain linux mdadm, no lvm layer

I did but it is error on iscsi.
I also tried testdisk but didn't solve problem, it found only 450 GB disk instead of 3 Tb
I also found some 1TB iscsi files, but don't know if there is something usefull in

the old drives have your old system ..if it was working then..it should work now

It looks like there is a some mess on old disk too.
Is there a way to recover iscsi disk from files? One is latelly one is 3 years odl and one is from august? each of them is 1Tb
I have 3 files on disk called
iSCSI-qnap-53cd1d36.001
iSCSI-qnap-53cd1d36.002
iSCSI-qnap-53cd1d36.003
