Hello, Here's the story: I started with a 5x6 TB raid5 array. I added another 6 TB drive and started to grow the array. However, one of my SATA cables were bad and the reshape gave me lots of I/O errors. Instead of fixing the SATA cable issue directly, I shutdown the server and swapped places of 2 drives. My reasoning was that putting the new drive in a good slot would reduce the I/O errors. Bad move, I know. I tried a few commands but was not able to continue the reshape. I then took out the server from the rack and replaced the SATA cable. No more I/O errors, but at this point I am unable to recreate the array. This is when I really started to panic. After multiple attempts at rescuing the array, I tried running the Permute_array.pl script [1] with some local modifications to additionally try different chunk sizes. So far I've had no luck. I don't remember what commands I have run. I have the OS on a separate drive, i.e. /var/log and /etc is intact. raid metadata version is 1.2. Ubuntu 16.04.02 LTS Kernel 4.4.0-72-generic mdadm 3.3 Is there any help you can offer?
