Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Checking that no-one is using this disk right now ... OK Disk /dev/sda: 3 TiB, 3298534883328 bytes, 805306368 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes After trying to add it to the array: Mar 20 17:27:07 Tower emhttp: writing GPT on disk (sda), with partition 1 offset 64, erased: 0 Mar 20 17:27:07 Tower emhttp: shcmd (118): sgdisk -Z /dev/sda &> /dev/null Mar 20 17:27:08 Tower emhttp: shcmd (119): sgdisk -o -a 64 -n 1:64:0 /dev/sda |& logger Mar 20 17:27:09 Tower kernel: sda: sda1 Mar 20 17:27:09 Tower root: Creating new GPT entries.

Mar 20 17:27:09 Tower emhttp: shcmd (120): udevadm settle Mar 20 17:27:09 Tower emhttp: invalid partition(s) Don't know it will work for what you need though... ETA: disk can be an image or passing-trough a 512e disk using /dev/by-id/ but making it look like a 4kn disk. Edited March 21, 2017 by johnnie.black Quote Link to comment
