That did it, awesome! Thanks a bunch for all the help.

Oh okay, I think I'd prefer to sort it out before updating then. So what are the next steps if we continue where we left off yesterday?

@JorgeB Side note, would an update to 7.1 help or is that a bad idea at this stage until my current issue is sorted out?

Hi @JorgeB! Thanks for taking the time. Here are the diags after doing what you suggested. Linking a screenshot as well of what it looks like currently. edi-diagnostics-20250323-1129.zip

So to clarify the Samsung 840 Pro that is currently unassigned is the OLD drive. The drive currently assigned as Cache 2, Kingston 2 TB, is the NEW drive. What I've done so far is the following 1. I added the new drive to the pool and let them go through the balance process. 2. When that was done I stopped the array and unassigned the old Samsung 840 Pro. 3. I then started the array again and waited a while before stopping the array to change back to 1 slot. This is pretty much where I am now. As it is currently I can not start the array and can not change back to 1 slot. Should I "move" the new drive to the first position sort of like this and then click "Yes, I Want to do this"? Watching the video you posted, I guess that is the process I should've used instead of this one which at first glance seemed more straight forward...

Hi! I've been "using" (read started and basically let it run) unraid for going on 4 yrs and thought it was time to swap out the old sata cache ssd for a nvme drive. However I think I messed up. After some searching I followed a reddit post that seemed straight forward. I added the new nvme drive to the cache pool and let it balance. When it was done I stopped the array and unassigned the old ssd and restarted the array. After a while I stopped the array again to change the slots back to 1 but I can't. And now here I am where the array won't start with the error "Wrong pool state". I can't change the slot count to 1 either. I looked at the thread by @FrForget and @JorgeB but I don't think I have the same issue. I included diagnostics and a screenshot of the cmd line asked in that thread. What do I do now? Thanks. edi-diagnostics-20250322-1456.zip

Yup, that is exactly what is happening, which I find reaaally weird! Yeah.. probably have to do that, I gave this thread a try first though since the OP had similar issues. Thanks!

I have (now) but it doesn't really provide any more info, that I can see anyway. I do have the guest network set as a separate SSID and password. However neither the Unraid or my PC is connected via WiFi so I find it rather strange.. If I enable "Access Intranet" it starts working again as well but that kinda defeats the purpose of a guest network imo. I've attached a couple of images below of the guest network setup screens of the router.

Hi, sorry to open this thread back up but I've had the exact same issue and just like you disabling the guest network immediately solved it (thanks for that!). Have you figured out a way to have the guest network up and still be able to access Unraid? To clarify: When I enable the guest network on the router I'm no longer able to access the gui/shares via my Win 11 PC. None of these are connected via the guest network. I could however connect to the web gui on my phone with the IP. The router is a Asus RT-AXE7800.
