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): http://lists.freebsd.org/pipermail/freebsd-stable/2011-June/062999.html -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
