Last update: after disk5 partiy build its showing up green in array and all good. Thanks a lot to @trurl for helping me out.

Thanks a lot. Thats exactly what's happening now

Parity rebuild is in-progress now to disk5. Its showing yellow rectangle with this message "disk content emulated", is this expected until parity build is complete? I believe 2 days ago. Right, i have disk share enabled. I had some issues in past and needed to see contents on some folder that got spread across all disk. Thanks for pointing it out, i will disable them. I only use user share when needed, not disk share.

Did this and UD can mount it, nothing in the disk. Do I add it back to array or you suggest to format it then add?

Yes, I want to make sure nothing is in the physical disk. Do I just unassign from array and load in unassigned disk to check for content as you suggested?

Noted. I have a disk to add another parity, just been putting it off. I will do that now and setup notifications as well. Thanks!

Unfortunately no. I periodically check if there is any issue/update pending. I will setup notifications. I dont want to remove the disk if there is no issue with disk. Can you advise if I got this right: 1. stop array 2. unassign disk5 3. rebuild parity without disk5 4. After parity built is complete, stop array 5. assign disk5 again 6. re-build parity

I didnt do any formatting recently, server have been in same state for many months now until recently this disk issue. I think its been around 3 years.

I did exclude this disk from all shares. Didn't do anything manually.

No, never reformat the drive since adding to the array. Here is the result: root@homeNAS:~# ls -lah /mnt/disk5 total 0 drwxrwxrwx 2 nobody users 6 Jul 7 11:41 ./ drwxr-xr-x 15 root root 300 Jul 7 11:31 ../

Thank you for checking the logs. I dont recall what was the status of the disk5 before I noticed the issue. It was never setup to be empty. Its showing it have 27GB of data on it (which is pretty low since this drive was in the array since beginning). Can you please advise what can I do now?

Please see the screenshot. When I hover over the red X tooltip says click to spin-up the drive, when I do that drive still have same red X beside it and contents are not displayed when I check the disk in explorer. I have not done anything yet that will impact the drive. Array is still up and running on same situation. Only change I have done is excluded the bad drive (disk 5 in my array) from any share. Thanks a lot for helping.

Here is the guide I landed on when searching on this issue https://wiki.unraid.net/Shrink_array#:~:text=Make sure that the drive or drives you are removing have been removed from any inclusions or exclusions for all shares%2C including in the global share settings. Shares should be changed from the default of "All" to "Include". This include list should contain only the drives that will be retained. Attached diagnostic log homenas-diagnostics-20220727-1218.zip

Hi everyone. I am on unraid version: 6.9.2. Recently one of my drive failed (red cross mark beside it) and it wont turn on at all. How can I safely remove it? I dont have a replacement drive of same size, I have a bigger driver that I will add later. Not sure if I can just replace the bad drive with new bigger one and have parity rebuild safely. I have checked all FAQs, but they all advise to move data to other drives, which I can't since drive is already bad. Thanks in advance for any suggestion.
