Solved ada0p* disappearing after mounting zfs root

A

alinxv.iso

I recently installed 14.2-RELEASE and upgraded to 14.3-RELEASE, and chose zfs and my root partition during initial install. The order of my partitions was messed up since the root was made before the swap, so i booted my linux partition and fixed the partition order using fdisk, but after doing that, my partitions have disappeared from /dev/ada and now i need to use /dev/diskid. Is this pure user error and can I fix it?

I have also mounted it on linux and set the mount using "doas zfs set mountpoint=/freebsd root" so I'll try to fix set it back to "/" later. This also happens on the 14.2-RELEASE live DVD.

The partition showing freebsd-swap is actually a udf partition i made in linux that i mean to format to swap, but i haven't been able to since my partitions won't show in bsdconfig.
 
Please add following two sysctl(8) keys to /boot/loader.conf and reboot system:
Code: 
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
This should populate /dev/ada0 with partition device nodes, and the ZFS pool will get the wanted device name ( /dev/ada0p5). Also, gpart(8) will show now the device names instead of diskids.

You can display a short description of the keys (or OID - Object ID) with sysctl -d <key>

when you're mounting a ZFS in a rescue environment, you should use mkdir -p /altroot; zpool import -R /altroot pool to avoid having to muck with the mount points of the datasets.

Keep in mind the CD and DVD images are read-only, even if you 'burned' them to a memory stick. You won't be able to create that mount point there. You can use /tmp/altroot for example as /tmp is a writable tmpfs(5) filesystem. The installer itself uses /mnt as altroot.
