i change it to sdk1 - the first drive in pool I got this: root@BigServer:~# btrfs-select-super -s 1 /dev/sdk1 using SB copy 1, bytenr 67108864 root@BigServer:~# What thats mean ?

The server its a buddys, but he says he not change anything. I think its a fubar SSD drive - thats why i will copy the VM out, and pull out the fubar SSD and then format the pool.

When i run btrfs-select-super -s 1 /dev/sdg1 root@BigServer:~# btrfs-select-super -s 1 /dev/sdg1 No valid Btrfs found on /dev/sdg1 Open ctree failed

Its correct, Pool/cache its Raid1 when there its more than one drive ?

Nope - 1 harddrive - Disk2 got a fail and jump out of the array. Then the Pool says this after reboot. Disk2 its online right now, and i copy all data to a new drive and put Disk2 in the trash efter this. But what happend to Pool SSd, i dont know - but i have a VM image i want to recover from the cache/pool. Right now, i try BTRFS reapair - and i says really many times: super bytes used 261601894400 mismatches actual used 261601878016

Hello! I have a real big problem... My setup its: [url=https://ibb.co/YB31tTb][img]https://i.ibb.co/TMk7Hqr/Sk-rmbillede-2022-09-03-144031.png[/img][/url] https://ibb.co/YB31tTb But i have many problems with my setup, but one of them, its my Pool dosent work. and stupid i was. I dont read what Pool was 1. time i install Unraid. So i have install all my stuff in cache drives, instead of Array drives. I know its stupid, 2 years after and understand Unraid a little better. But it dosent work today, and i dont know how to fix i. Next its, i have one VMs in there - and it will be so cool, if i can recovery the VM image og better, recover everything, and then i can move to a array drive after. Can someone help me here ? bigserver-diagnostics-20220903-1448.zip

Its first time i set an unraid system up, and i got problem with space all the time - but i can see the answer was lower in this thread. VMs and Docker + Plex its running on the cache disk, at thats not so smart, i can see that now, when i understand how its work. The system its updated from RC2 to RC4 - and then all the problems start. And Yes, i now the problem with disk2 - The problem its, its crash some times and the system its not very stable with this hard drive. But i have an idea, that the priority hard drive has the data. So i took the disk2 drive out, and hope there come som guide to migrate data to a new drive. At same time the update RC4 also installed. Its disabled now Drive2 has some problem - i look for at guide to migrate all data from Drive2 to Drive"recovery". But i couldt find a guide thats work. There was a cowboy trick in the forum, how to get the cache back i normal state - i took a empty cache drive, off the pool and in the pool again. but that not work. And then i found the this thread - and now i beginning to understand the problem - but the biggest problem its the begging setup, i can se that now. But i still not understand, why have a priority drive, if the system not can copy the lost data from lost drive?? But i think i will begin from beginning again. Are there a easy way, to copy all the data from data pool and cache pool (or its dead?) to a drive i put in the server - and setup up the system again - with the right parameter and the right file system. And then copy all the data back again ?
