For T311591: decommission db2075 and T311589: decommission db2071 I ended up with the following error (for both hosts):
----- OUTPUT of 'lsblk --all --ou...-all --force %*'' ----- /dev/sda: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54 /dev/sda: 8 bytes were erased at offset 0x3a2c7fffe00 (gpt): 45 46 49 20 50 41 52 54 /dev/sda: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa /dev/sda1: 2 bytes were erased at offset 0x00000438 (ext4): 53 ef wipefs: /dev/sda2: failed to erase swap magic string at offset 0x00000ff6: Text file busy ================ PASS | | 0% (0/1) [00:00<?, ?hosts/s] FAIL |█████████████████████████████████████████████████████████████████████████████████████████| 100% (1/1) [00:00<00:00, 1.55hosts/s] 100.0% (1/1) of nodes failed to execute command 'lsblk --all --ou...-all --force %*'': db2075.codfw.wmnet 0.0% (0/1) success ratio (< 100.0% threshold) for command: 'lsblk --all --ou...-all --force %*''.

The rest of the decom process went fine.
Both hosts were up and running normally before the decommissioning.
