Yes sir that is correct.

will do, thanks

Okay great. If I create the new pool and send you photos would you be willing to send the commands?

If that doesn't work then my next plan is the one I outlined yesterday with a slight twist. I was hoping to get new 12TB drives but that is out. I do have on hand a bunch of 8TB drives so my new plan is to create a new temporary pool with the 8TB drives. Then use the commands you offered to send to replicate the shares over to the temp pool. After that reformat the old raidz2 into a new raidz with only 4 drives. Then use the same commands to move the data back from the temp pool to the new pool on the raidz. Would that work?

Okay so the plan has changed slightly, and any help you can give me would be great. So I need to switch from a case with an 8-drive bay to a case with a 4-drive bay. In an ideal world, I would just somehow convert my current 6 drive raidz2 to a 4 drive raidz1. Is there any way to do this without reformatting and losing the data?

I have another quick question if you don't mind. I'm thinking about switching my hardware around and going from a 6 10TB drive raidz2 to a 4 12TB drive raidz1. Is there a simple way to migrate the shares and pool data?

Check your Paypay for a tip/beer. From DarkOmen44z. Thanks again, Cheers!

It looks like its resilvering

I think we are making progress

Yes I ran that command but it doesn't seem to give any feedback on if it was successful or not

OKay now im getting this "cannot replace 7931583891141304603 with /dev/sdg1: already in replacing/spare config; wait for completion or use 'zpool detach'"

Roger that. I did it with the array started and The first command was fine. The second is kicking out this. "cannot remove /dev/sdg1: Pool busy; removal may already be in progress"

Should I stop the array to do this?

So I had a "Hot spare" already assigned to the pool when the drive failed. When the system didn't automatically swap out the faulted drive for the spare, I just removed the spare, and added it as the 6th drive in the pool. I figured it would re-silver and be all set. So there should be 6 good drives in the pool right now, and no hot spare. So to answer your question I thought I already did replace the faulted disk, with the hot spare. Did I do something wrong?

So I just got home and re checked and it still says the pool is degraded when I click on it. But on the main page it shows all the drives green and healthy. Which is correct?

Okay thanks. I will try this when I get home. Cheers

"I can then post the instructions to removed the slog" Can you send me these? Thanks again.

Thanks. I had a bad drive last night but I had a spare drive on hand and I have fixed that issue. That brings me to another question if possible. I had a drive in the pool as a hot spare. When a drive in the main pool failed I waited and was expecting the system to just do its thing and replace the failed drive. but it didn't. I then just manually replaced it so that the problem was fixed. it now shows as healthy. Does having a hot spare mean it will do anything automatically? or will I always have to move it up to the main pool? Feel free to send those steps. Again, I can't thank you enough!

I have attached the diagnostic file as requested. Thanks so much! unraid-diagnostics-20240827-0747.zip

I'm new to Unraid. I set up a 6-disk raidz2 that I'm happy with. After that I had a couple of extra nvme's so I added them as cache, and slog drives to the pool. After learning more I found that I don't need them as Ram handles so much of that duty and I have enough of that. So I went to remove the two drives. I started with removing the cache drive and the pool mounted fine. Next, I tried to remove the slog and it wasn't happy and won't mount the pool without reformatting. Can anyone tell me the correct way to remove this slog without reformatting? Thanks so much, everyone.
