I ended up finally being able to promote /ix-apps/app_mounts/tailscale-1.2.7-clone with “zfs promote”, and then ran zfs destroy -r mnt/ix-apps/app_mounts/tailscale-1.2.7-clone, it destroyed the snapshot, it no longer appears in the snapshots tab, but when I try to disconnect pool, I still get the “[EFAULT] Failed to stop docker service: [EFAULT] Failed to umount dataset: cannot unmount '/mnt/.ix-apps/app_mounts/tailscale-1.2.7-clone': unmount failed”
Here’s my full shell:

Also tried killing the process again, here’s the shell:
root@truenas[/mnt/.ix-apps/app_mounts]# ps ax | grep tailscale
1155464 pts/3 S+ 0:00 grep tailscale
root@truenas[/mnt/.ix-apps/app_mounts]# kill 1155464
kill: kill 1155464 failed: no such process
Now ran a command to see if I could locate the parent process, I think I found the parent process ID that doesn’t change, but can’t kill it for shit:
root@truenas[/mnt/.ix-apps/app_mounts]# ps -o pid,ppid,cmd -U root | grep tailscale
1169788 1126922 grep tailscale
Going to repost everything to a new thread that’s better formated
