Hi, you were right, it was a correcting parity check. And I've got rid of all power cable splitters, and all runs well and it feels solid with stable power delivery. I've lost many files but mostly media files, nothing too serious. I thought the problem was solved so I deleted the diagnostics And I'm grateful for all the patience and help all along. Thank you! And community!

I can access the folder through the specific disk, but not from the share folder which says invalid path. Is the folder created in the disk where the files originally located? If so I might know what they are and how to deal with them, millions of folders lol Thanks for the reminders, I'll see to the connections after the parity check. Thanks for the support!

Update I've managed to rebuild and repair the whole system after several times of rebooting, rebuilding and formatting and parity check. I now believe the problem might be caused by hardware issue as every time I opened up the machine, something wrong popped up. I gave it 3 days for the whole data rebuild, the rebuild speed changed dramatically, but it completed at last, and I formatted the unmountable disk, thus lost all files from the original disk 1(toasted). then the disk 2 showed up as unmountable, but a filesystem fix then solved it. After rebuilding and checking and fixing corruptions the system shows all green for now. Now I see a 490G lost+found folder showed up located in disk2, i failed to go into the folder. Wondering if you may point me the way to restore whatever is in the lost+found folder? Also latest diagnostics attached, would you be so kind to check if everything is alright now? Any potential risks? Also I haven't done memtest yet, I know I shall do it sometime. Thanks in advance!

Understood, let me find a monitor with vga first

Is the live memtest plugin sufficient? Thanks!

So sad and strange. And no sir, no memtest done recently.

Rebooted without the failed old disk, nothing assigned, diagnostics attached. Now sdd is showing as unmountable...

Disk 1 unassigned, please see attached diagnostics. Thanks!

Sorry for the confusion. I meant the former parity sdb... Currently sdc. Is there any way I can fully cancel the rebuild, and lose this disk, format it and add into the array? I've backed up most of the files so should be ok. Thanks!

Or perhaps there is any way to stop this rebuild process, to totally ignore the swapping and copying and add back sdb formatted as new while remain the other disks and array config untouched? I can withstand the minor data loss of that one disk. Thank you!

I think the following I did was why sdf thinks it has a valid filesystem because when I was messing up to start it I put it in the parity swap slot in the config to try if it can be started.. As for sdg, I've tried changing it's physical slots, re connect, but I think the disk itself may be broken physically, as it's buzzing when spinning.. could this be reported as the connection problem? Thanks!

Sorry my typo, sdg, 2t, the original failed disk, sdf, 16t, a new complete disk.

Sdg is the 6th new disk, prepared for expansion.

Screenshot attached.

Yes sir, sdg is the original failed disk. The machine has 6 sata ports splitting into 3 controllers each with 2 slots, if this is what you were referring to. Confirm plugin installed. Waiting for instructions. Thx!
