Hi,

As a start you can use these in /boot/loader.conf to prevent the confusion about gptid or disk_ident. I disabled gptid at my computer. But if I understand you would like to disable disk_ident. For ZFS it should not matter what you use.


$ sysctl kern.geom.label
kern.geom.label.disk_ident.enable: 1
kern.geom.label.gptid.enable: 0
kern.geom.label.gpt.enable: 1
kern.geom.label.ufs.enable: 1
kern.geom.label.ufsid.enable: 1
kern.geom.label.reiserfs.enable: 1
kern.geom.label.ntfs.enable: 1
kern.geom.label.msdosfs.enable: 1
kern.geom.label.iso9660.enable: 1
kern.geom.label.ext2fs.enable: 1
kern.geom.label.debug: 0

Further. Does ZFS see 14989197580381994958 and gptid/31be0527-84f0-11e6-bbbc-fcaa14edc6a6 as the same disk? Zpool replace also has an option to replace the disk 'with itself'. Just provide it one parameter like this:
# zpool replace tank 14989197580381994958
or
# zpool replace tank gptid/31be0527-84f0-11e6-bbbc-fcaa14edc6a6
Does that help?

Oh, while I read your mail again. You have 2 GB swap configured on the disk so wiping 2MB at the start of the disk does not wipe the freebsd-zfs metadata of the da14p2 partition. Try wiping 3GB from the start and end of the disk and repartition it.

Success.
Ronald.

Hello,

I recently offlined the device and after onlining it the label changed to
geom. After a few reboots the pool started importing by diskid. After
attempting to offline/online by gptid, would continue to fail with an
error. I decided try to replace it and is also failing with the error
above. I also wiped the first & last 2MB of the disk without success. Is
they're a known issue or perhaps I'm missing something obvious? zpool
labelclear is also providing a similar error. The -f options are not
helping.


Any ideas what my issue maybe? The error suggests it is currently active on
the pool, however the offline should have changed that status correct?
