It was faulty power cable. Array is now up. Sincere thanks.

Noted. But please check disk 2 smart report in before upgrade diagnostic, it was same and without touching hardware it is perfect now. Is is something to do with pendrive?

Hi. My configuration is 4 nos. HDD (1 Parity + 3 data) 2 TB each and one cache SSD of 240 GB. After starting the server array did not start as disk 2 & 3 were listed as missing and both could be seen as UD (with 4.14 GB size?). Went through missing disk threads on forum & got confused if I have to go for new config without loosing data. Then downloaded diagnostics & flash backup (time 1455). Upgraded OS from 6.10.9 to 6.12.2 latest and after reboot, disk 2 started showing as data disk & disk 3 is still UD. Now downloaded diagnostics (time 1306). Now array can be started & disk 3 I guess can be rebuilt. But I thought of seeking support first, what could be problem, how come disk 2 started showing automatically. There should be way to get back disk in array. It is not listed in dropdown of disk 3 slot. prashant-diagnostics-20230713-1455.zip prashant-diagnostics-20230713-1506.zip

Thank you very much. It really helped me. I love unraid because of all you supporting members.

Can you please provide similar commands for nextcloud?

Thanks for valuable tip, well noted. Since it is not having data, can remove it from array & is there way to tell config just to forget & rebuild parity without it?

@Frank1940, Now it's "clear" to me. If have to add disk to array then I'll just pre clear it for obvious reasons you mentioned above. Any if I plan to use it as unassigned device then only format it, post pre clear.

Basically being new user, I am just exploring things & get hands on experience of the features. I'll use it for storing data which perhaps is not important. I used Krusader, unassigned device, pre clear etc. On this hdd, till date which I had only read about it. Also with this disk I'll explore replacing disk etc. feature.

Thanks for clarifying & guidance.

Hello all, I'm first time user. With the help of all you guys & especially spaceinvader videos, I have successfully set up my unraid from scratch. Presently using trial key but will be purchasing plus key today as my unraid is successful. My configuration is as follows; Intel i7 8700 8th generation CPU Asus rog strix H370 F mobo Corsair vengeance 16GB 2400 mHz RAM single module 750 watts 80plus bronze modular PSU cooler Master K380 case Zotac GTX 1060 GPU KINGSTON A400 SSD 240GB dedicated for windows 10 Pro (dual boot application) KINGSTON A400 SSD 240 GB for cache 3 X 2TB IRONWOLF for array (1 parity + 2 data disks) SanDisk ultra fit 3.1 USB Flash 32 GB for OS It's my DIY project & only few days with system. My first question or rather observation in forum is as follows: Yesterday I added one 80GB Hitachi HDD, using Krusader, transferred useful data to newly created share, using unassigned device plugin removed the old partions, pre cleared it & formatted in XFS file system. I had read somewhere that such drive can be added to array without needing to clear it format again. But when I added this disk to array, it was put to clearing operation & post that was available as unmountable needing to be formatted again to be part of array. Without much thinking I completed the process. Something went wrong in my procedure? Is it normal? Repeating of clear & format function. Now I'm struggling with my first VM. I have ordered Ziyituod SATA3.0 Card, 6 Port pcie card for expansion. I understand that I can seamlessly shift my array drives to this card as unraid remembers the configuration by disk serial numbers and I need not do any additional steps, Please confirm my understanding. Also is it right choice for this card? Thank you all in advance & for my successful unraid built.
