Aren't GPT labels stored in the /dev/gpt directory structure?
If so, try maybe one of these two:
zpool replace zroot gptid/55ab4aad-f180-11e0-a060-0030488e9ff3 /dev/gpt/disk5
zpool replace -f zroot gptid/55ab4aad-f180-11e0-a060-0030488e9ff3 /dev/gpt/disk5
You might also try offlining the "gptid/XXX" entry first, then try a
normal replace.
After doing this (on each and every device -- your pool will need to
resilver too, every time), I imagine you will need to disable GPT IDs
entirely using a loader.conf variable (see this thread, read the full
thing):
