Sorry for the late reply but I wasn't able to turn off and on the array. I don't have the errors anymore so I suppose it must be related somehow to a bad btrfs.

Seems that was the problem, reformatted sdd to xfs (instead of btrfs). Stopped and started the array again and voila, working cache disk. So this is a bug?

Ok I will reformat that disk. Am I correct to think that when excluding a disk from the shares and running mover moves the data away from that disk? thanks!

Your commands did not do/find anything: wipefs -o 0x10040 /dev/sdg wipefs: /dev/sdg: offset 0x10040 not found wipefs -o 0x10040 /dev/sdf wipefs: /dev/sdf: offset 0x10040 not found One disk was empty so I wiped the other one with the other command: wipefs -a /dev/sdf1 /dev/sdf1: 8 bytes were erased at offset 0x00010040 (btrfs): 5f 42 48 52 66 53 5f 4d wipefs -a /dev/sdf /dev/sdf: 2 bytes were erased at offset 0x000001fe (dos): 55 aa /dev/sdf: calling ioctl to re-read partition table: Success I recreated the cache with only sdg, mounted fine. The next command returned nothing: btrfs device add /dev/sdf1 /mnt/cache I stopped the array and from the moment I selected 2 slots the green dot went to blue, adding the second disk made 2 blue icons Started the array and tried the following command anyway: btrfs balance start --bg --full-balance /mnt/cache Checking status: Every 2.0s: btrfs balance status /mnt/cache ERROR: cannot access '/mnt/cache': No such file or directory btrfs fi show /mnt/cache ERROR: superblock checksum mismatch ERROR: cannot scan /dev/sdc1: Input/output error ERROR: not a valid btrfs filesystem: /mnt/cache sdc is an array disk formatted as btrfs

Anybody?

Ok I've been trying some things: Cache slots was set on 2 because I wanted to add 2 drives. When I set cache slots to 1, it works?! Disk is then tagged as normal (green icon) From the moment I set the slots to 2 the first disk is tagged as new (blue icon) and unmountable This with either disk. EDIT: in disk.cfg cacheUUID is still empty, whereas on another test server I have an SSD mounted for cache and that actually shows an UUID

mkay, well thanks for trying

I'm not sure what you mean, the array is fine. It's the cache pool that is not working. I did use "was" fine but it should read "is" fine I've attached a screenshot to illustrate the problem

So I installed a new unraid. Assigned all disks for the array and cache. Everything was working.. until I rebooted the server. Array was fine but cache disk showed with a blue icon (new disk). I've tried (i think) everything (after manually copying the data back to the array): - format disks - wipefs - preclear - new config It all stays the same, disks with blue icons and no way to make it a cache pool. When I click format it says "formatting" once but when reloading the main page it's possible to click format again. Any help would be appreciated I tried a lot of searches but came up empty. thank you

So 9211 would be supported if I use it in RAID mode? or is any major brand RAID card supported? What would also interest me if you could check and see if you can get SMART info in unRAID from your RAID 0 disks and if it's available in the web GUI? It should be possible according to this: https://www.thomas-krenn.com/en/wiki/Smartmontools_with_MegaRAID_Controller thanks!

Thanks, somehow it did not show up in my search results. Just out of curiosity, why is this not in the wiki? In a lot of pages it says that it's outdated so it's a bit difficult to find the right information when the wiki shows up first I also get a download request when I try to search on the wiki itself Yes that was also an idea I was thinking about, but everyone speaks of extra SATA ports and disabling RAID. Which is of course the primary idea of unRAID but I can't find a compatibility list with supported RAID cards (in RAID functionality), can you point me in the right direction please? I did see a video of Linus Tech Tips saying that the RAID cards don't provide smart & status info, unless this has been added / fixed or can be provided in another way? LSI SAS 9211-8i HBA or LSI SAS 9211-4i seem like good options if it's supported. Thanks for answering my questions

Hello From what little information I could find it is possible to have a cache pool in RAID 1, correct? I'm just not comfortable yet with just putting my VM's on an array with a delayed parity checks so I would like protection. Now I'm trying to decide to go with unRAID if I can get "instant" redundancy in the cache pool. So I found reasonably priced Intel 600P 1TB nvme ssd's (yes not the fastest I know but I don't want to exaggerate in price) I'm open to buying 4 to get them to work in RAID 10 if such a thing is possible, meaning I would have 2TB cache. So I have these questions: RAID 1 cache pool? RAID 10 cache pool? If the previous applies: RAID 1 to RAID 10 conversion possible? Thank you!

Hello I'm very much interested in unRAID but I'm a bit lost in the hardware for VM passthrough. So I would think to get Supermicro X11SSH-LN4F and a Xeon E3-1275 v6. Now the CPU has HD Graphics P630 and the motherboard says it has an Aspeed AST2400 BMC for graphics. So now it's unclear to me that while it is a new CPU, does it support GVT, because on certain articles I read it should be gen 4 or newer and others say only Iris Pro. The mother board has Aspeed, does this mean I wouldn't be able to access the HD Graphics or would I? thank you!
