I can't thank you enough. So many questions: 1. Are you an LT employee? I see you saving so many people and you're awesome. 2. Have you ever thought about creating/posting a knowledge base workflow? I see you answering questions like this a lot. Like, how did you know to "do this" then this based on the output? Would it beneficial for you to create something as a guide for people to walk through first? 3. You think my SSD is actually failing or is it a known problem that they sometimes only re-appear after a hard shutdown/reboot? 4. If my drive wasn't recoverable, what would my nightly CA backup provide me if anything? Again, thank you for your time.

On the step where I re-add the devices and start the array. Should I change the FS from "auto" to "btrfs" since my cache pool was originally a shared-non-raid pool of 4TB total?

I have 2 NVME drives in a pool not in Raid 1(dumb, I know). One seemingly stopped working so I rebooted to see one drive was missing. I then attempted the following steps. Thanks for the help. 1. Started/Stopped the array. 2. Made a new cache pool with the one working drive and started the array. 3. Got the Unmountable error. 4. Hard rebooted the server which came back up and found the missing cache drive. I realize it's probably dying, but I've had this happen before last year. SMART passes on this drive even now. 5. Created a pool with BOTH drives back again. 6. Still got the Unmountable error btrfs fi show Label: none uuid: c21ac1df-edb4-4149-8b0f-b992d5d3f776 Total devices 1 FS bytes used 14.32GiB devid 1 size 20.00GiB used 18.52GiB path /dev/loop2 Label: none uuid: 95ca501b-f019-4e4d-8084-84a0a285b8e2 Total devices 1 FS bytes used 412.00KiB devid 1 size 1.00GiB used 126.38MiB path /dev/loop3 warning, device 2 is missing Label: none uuid: 754b3e32-4ddf-4175-9c82-17006b7525a3 Total devices 2 FS bytes used 163.99GiB devid 1 size 1.82TiB used 133.01GiB path /dev/nvme0n1p1 *** Some devices missing

I'm sure this has been answered and I did search the thread. Maybe, my old man eyes or brain isn't working. Sorry and thanks in advance. I'm getting the RETENTION WILL NOT BE CHECKED!

Works great when I'm away from home, but noticing some network issues since installing a month ago. 1. Sometimes I can't access my Unraid server when I'm on a local machine without tailscale active on the client. Rebooting the Unraid plugin seems to help. 2. Plex users are saying their streams will stop every 20 mins or so. Not sure if it's Tailscale related, but figured I'd upload the diagnostics. Thanks. Hera-tailscale-diag-20230917-101241.zip

I spent some time thinking about it and went with this part list. Just finished running memtest overnight and I'm about to load up Unraid. https://pcpartpicker.com/list/Nw4hW4 I think the thing that scared me the most was the Supermicro mobo potentially not supporting the CPU out-of-the-box without a bios update. I also wanted 10GB on the mobo.

Will be using it with some normal hard drives(WD Red Pros) not SSDs. There's about an $80 difference on eBay from what I see (already flashed in IT mode). Which should I go with? Also, I keep reading about heat and seeing people rig a 40mm fan directly on it. If performance is the same, meaning given I'm only using spinners...is there a difference in heat? If there is a concern about heat, should I attempt to attach a 40mm fan or find some type of bracket. I have no idea what type of bracket either. Thanks.

Whoa, awesome info. Thank you @Hoopster. How come I rarely see Supermicro mentioned for motherboard choices? It's usually Asus, Gigabyte, and ASRock. So with that OCuLink cable, are you saying I won't need a controller then? Am I turning one motherboard SATA port into 4? Does that affect r/w speeds? You think air cooling is good enough for the 13th gen Intel? The gaming folks water cool them. Do we typically need it for a few 4k transcoding streams?

I think I'm ready to build my second Unraid server. Some things I'm pretty sure I want: 13th Gen Intel: i9-13900K, i7-13700K or i5-13600K? I dunno...these keep coming up. 10GB network. Reading here 2.5GB isn't great? 2-4TB SSD cache pool. A pool of two drives is faster? Two 2TB Samsungs? 12 SATA drive support(Rosewill chassis has 12 hot swap). A motherboard with enough SATA connections that I would only need 1 additional LSI expander. As in, can someone recommend a motherboard that has 4 SATA connections then I get an expander with 8? LSI expander in IT mode. So much info on these boards and I can't dig my feet into the sand on a choice. Things I don't know much about: Is having a separate network card better than having it built into the motherboard? Does Unraid still have issues with Intel HW transcoding with the 13Gen chips? Is having multiple SSDs in the cache faster than just one for reads/writes? Will hard drives have different speed performances if connected directly to a SATA port on the motherboard vs an expander? I know this is a big ask, but it would greatly be appreciated for some compatible parts I can pull the trigger on. Any similar parts picker lists I can just steal? Thanks.

Probably overthinking this, but I'm about to put together a new build to replace my functioning unRAID server. I mysteriously was able to put a build together with the Norco 8 years ago, but I'll be honest when I say backplane talk confuses me and I don't know how the case/sata can limit my system. Replacing all the hardware, but should I reuse the Norco case? Any benefit to buying the Rosewill? I would think copying data to the new drives/build would be easier with less down time. If I reuse the case, I would think I would have to swap my parity with a new larger drive and add the other new drives then unbalance it with the plugin. Then swap the old internals with the new build keeping the new parity and data drives. Thanks for the advice.

Thanks for this. Nope, nothing holding me back from updating Unraid. I think Unraid had some bad releases last year which scared me. Plus I haven't updated any of my HW bios...not even sure if that's a factor. Yeah, so I am somewhat concerned about the age of the disks and system. I guess I'm probably just unnecessarily nervous to even get hands on with the current system as it's still working. Family and friends also use it so if I screw up I'll have to answer texts.

Gotcha, thanks @trurl and @Kilrah for the clarification and education. Soo...without a magic eight ball...you think 8 years is enough for a NAS? I feel like I don't have much life left(sound about right?), Unraid is running an older version, and I have to keep dupe movie resolutions because it can't HW transcode.
