ZFS is now listing my disk devices by their gptid names, ie # zpool status pool: nfsen state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM nfsen ONLINE 0 0 0 mirror ONLINE 0 0 0 gptid/55c03af2-5c54-11df-af69-001143d8b2eb ONLINE 0 0 0 gptid/58ef6152-5c54-11df-af69-001143d8b2eb ONLINE 0 0 0 errors: No known data errors Previously they were showing as ada0p1 etc. I was quite happy with the previous method as I'd fixed the device names via /boot/device.hints and this made it (to me) perfectly human readable without having to use labels. Is this something that in 8.2 is now hard coded into ZFS? Ie I am forced to use gptid or disk labelling? thanks Andy.
