Accidentally removed a QNAP storage pool instead of detaching. Pretty sure the data is all there, I just don't know how to mount it.

[ianyp]

My setup is two NVME drives and two 16TB HDDs (RAID 0)

I wanted to reinitialise my NAS; I didn't want to lose the data on my main HDDs, so I intended to 'safely detach pool', but instead did 'Remove Pool'. I'm sorry my error.

I'm convinced I didn't get a data loss warning (even though the docs say it should give one).

Then I physically removed the drives and then reinitialized the NAS.

I configured the basic settings, then reseated the two physical drives and I can see them listed under Disks/VJBOD. I went to Storage & Snapshots -> burger menu -> Recovery -> Attach and Recover Storage Pool. It doesn't find any pools. The pool is not password protected.

How do I recovery my storage pool? I have access to linux workstations if necessary, and I'm a confident shell user.

From ssh I can still see the partition tables on the drives in question. I have a backup of the NAS settings pre-reset, but it's as a bin file.

Maybe try emailing/calling QNAP support or asking on the QNAP forums?
You paid for a ready made device for the support, no?

I have already submitted a ticket, but I believe the response time is around 5+days, so I thought I'd call on the expertise of this forum.

You may get a faster response and more specific knowledge in the qnap forums. Here it can be random on the response.
