June 1, 20233 yr Good evening, I could use some clarification on the 'Shrink Array' documentation under 'Unraid v6.2 and later' procedures. At what step in the procedure for "The "Remove Drives Then Rebuild Parity" Method" do you physically remove the drives? Secondly, in the "The "Clear Drive Then Remove Drive" Method", if you clear the drive via reformatting, do you still have to run the script? Couldn't you just jump from step 4 to 9? Thank you for the help. V

The only thing that matters is the disk to be removed is not assigned when you rebuild parity. 2 minutes ago, veemann said: clear the drive via reformatting A formatted disk is not a clear disk. A formatted disk contains an empty filesystem. Only a clear disk can be removed without invalidating parity. A clear disk is all zeros so has no effect on the parity results.
June 1, 20233 yr Author Thank you for the response. Then drives can be physically removed at any point? Even reformatted to a different file system the drive is still not 'cleared'? Thanks again. V
