Use an empty disk from the array to replace a failed disk

[threiner]

Hi , guess it is somewhere explained but i cant find it... how do i replace a failed drive with an empty one what is already in side the array?

That is not a supported option.

 

once a disk has been added to the array and formatted then it is no longer ‘empty’ as far as parity is concerned because although it may not contain any files it has the directory structure representing an empty file system that was created by the formatting process and parity had been updated to reflect this.

ok but ther should be a way to take one drive out of the array or also not???

You have functionally already taken one drive out of the array: the recently deceased drive. You must now add an additional drive to the array and allow that drive to be rebuilt from parity. Your "empty" drive is fully assimilated into the party maths and must be accounted for thusly. It cannot be removed until after this procedure has been followed.

i was going to replace the drive unraid disabeld, but unraid is not showing anymore the details like serilnumber of the drive. How do i find out the serial of the drive ?
