Pool dataset is missing, can't even open the tab.

[MateusMat]

I don't know how to describe my problem. One day I couldn't access my NAS. I could boot it, but it wouldn't do anything. From the machine it had the common screen with the address. On the web interface my pools were missing. I tried to import them and it just say it was importing and even hours after nothing was done.

I updated the boot pool to the lasted stable version. One of my pools I was able to import but the other didn't, kinda. I was able to import, but it didn't show anywhere. Not in the status page, nor the storage page. I could list the disks, and it said it had the pool.

I couldn't unlock any of the datasets. Going to the page would just keep on loading and never show my datasets.

I physically unplugged the disks of the pool that didn't import. And the webinterface was back to normal. I was able to unlock the datasets. Set a new share, and access my files.

So I physically unplugged the working pool disks, and plugged the other one. Again no pool was showing. I couldn't import as it said I already had a pool. And I couldn't open the dataset page as it just kept on loading. (The entire web interface became laggy as hell).

I destroyed the pool... and recovered. And still not able to open the dataset page.

pool: Slayer

errors: No known data errors

I don't know what to do now. If I could at least access the files temporarily I would save them and destroy the pool permanently.

As far as I see all the drives are working correctly.

I don't know what else to do. I've spend the last few hours trying to fix this and have to work in 4 hours. So I'm gonna try get some sleep. And I'll try and reply to any suggestions latter.

Thanks in advance.

It would be nice if you tell us details about your hardware.

Right... Sorry.

It's an old PC.

CPU: AMD FX-8350 Eight-Core
RAM: 16Gb DDR3 1400MHz
Motherboard: ASUS M5A97 R2.0

Boot-pool is a generic 120gb Sata SSD

Illyria pool, (the one working) are 4 4Tb Ironwolf NAS disks in a single Vdev in Raid5.

Slayer pool, (the one with the problem) are 2 2Tb Seagate disks in a mirror Vdev, and 2 1Tb WesterDigital disks in a mirror Vdev.

To add to this...

I'm using a PCIe to Sata expansion.

My motherboard has 6 Sata slots... the PCIe expansion has 6 more.

Before the problem... Illyria pool was on the motherboard while Slayer was on the expansion card.

When disconnecting and connecting each pool, I connected Slayer (The one with the problem) directly to the mother board.

After waiting an hour on the webpage for the dataset after a pseudo successful import. It showed.

I was able to unlock it... but despite the mount partition on the NAS showing the pool, it has no files.

The funny and weird thing is that on the Storage page, the pool still doesn't show.

Went back to the dataset page, and got this error.

Can someone help me please. I just need to retrieve my data.
