Hi everybody.

I need help with the same problem on my server.

I made a parity sync, then replaced with a bigger disk I had brand new, formatted it and pre-cleared It, it directly showed un-mountable. tried reformatting it, tried another disk, tried the old disk, it never came back as normal.

I also tried to update unraid, parity sync with the un-mountable drive  and other things I could think of  but nothing ever worked. (even repair the disk in safe mode, but I wasn't convinced of the work it done (I think nothing happened at all three bad knowledge).

I don't want to lose too much data. (my system is still emulating the missing disk)

Thanks a lot to you all and hope you can help me.

Respectfully

The release you are using has a known issue formatting disks >2TB, update to v6.11.5 then rebuild the disk again, don't format, just unassign the disk, start array, stop array, re-assign the disk and start array.

thank you @JorgeB at least your answer was very clear  it seems to work .

before your answer i tried to understand the other unsupported topic and couldn't make a sense to it  (maybe my bad english) 

 

so thanks to you and to the community
