root@truenas[~]# zfs mount -a
cannot mount 'TankPrincipal': mountpoint or dataset is busy
root@truenas[~]#
I tested exactly this, and the results were as follows.
Imported the pool read-only (without -R /mnt, since it’s not TrueNAS.)
zpool import -o readonly=on testpool
Then issued the simple command, as @HoneyBadger wrote:
zfs mount -a
And here are the results for all datasets, including children:
testpool on /testpool type zfs (ro,noexec,noatime,xattr,noacl,casesensitive)
testpool/ds1 on /testpool/ds1 type zfs (ro,noexec,noatime,xattr,noacl,casesensitive)
testpool/ds2 on /testpool/ds2 type zfs (ro,noexec,noatime,xattr,noacl,casesensitive)
Caveat: This is not a TrueNAS box, nor did I use any “recovery” or “TXG” magic.

Could this be because there’s a remnant directory that still exists under /mnt/ ?
@Berboo Is there another shell window open (another PuTTy session perhaps?) that’s in the /mnt/TankPrincipal directory?

Wow there is indeed TankPrincipal now in /mnt. But nothing inside it :
root@truenas[~]# cd /mnt
root@truenas[/mnt]# ls
TankPrincipal
root@truenas[/mnt]# ls /mnt/TankPrincipal
root@truenas[/mnt]# cd /mnt/TankPrincipal
root@truenas[/mnt/TankPrincipal]# ls
root@truenas[/mnt/TankPrincipal]#
Can you make sure you’re not “using” this directory in any way?
See @HoneyBadger’s post above.
There’s also the rmdir command, but considering your luck with anything rm-related, I’ll let someone else suggest that.
But how that TankPrincipal appeared in the first place ? Few posts ago there was nothing under /mnt.
Anyway, I closed all Putty sessions, closed any Chrome Tab with TrueNAS.
How about sudo zfs get mounted,mountpoint,canmount and let’s see if any of your other filesystems remember where they should wind up?
root@truenas[~]# zfs get mounted,mountpoint,canmount

Let’s just go for the easy sudo zfs mount TankPrincipal first.
root@truenas[~]# zfs mount TankPrincipal
cannot mount 'TankPrincipal': mountpoint or dataset is busy
root@truenas[~]#
sudo lsof | grep /mnt/TankPrincipal ?
root@truenas[~]# zfs mount TankPrincipal
cannot mount 'TankPrincipal': mountpoint or dataset is busy
root@truenas[~]# sudo lsof | grep /mnt/TankPrincipal
root@truenas[~]#
Maybe it’s a dumb question but what about a reboot ?
@HoneyBadger: Safe to issue (or attempt) a rmdir /mnt/TankPrincipal ?
Rebooting will put you back to needing to go through the very long import -fFXT again which is why we’re attempting to avoid it.
@winnielinnie I don’t think anything’s holding that directory as shown by the lsof output. I’d almost consider the inverse and do mkdir /mnt/TankPrincipal/somedatasetname and try to mount one of the other datasets into it.

Additional you could try renaming the directory if it’s a directory and not a mounted empty dataset.

So I can go for
mv /mnt/TankPrincipal /mnt/Old_TankPrincipal
?
It may still fail with “directory in use” but that should be non-destructive.
