Post maybe output of zfs get all zfs-mirror-01 and stat /mnt/zfs-mirror-01.

That's interesting. Inode number for a dataset mountpoint should be `34`. What is output of df -T /mnt/zfs-mirror-01? What is output of filesystem.stat /mnt/zfs-mirror-01?

 

[schwartznet]

root@tssn-file-p10[/]# df -T /mnt/zfs-mirror-01

root@tssn-file-p10[/]# filesystem.stat /mnt/zfs-mirror-01
zsh: command not found: filesystem.stat

What version of ubuntu did this come from? I see sharesmb enabled and nfsv4 acls enabled (my code for this hasn't been merged upstream yet so that's a little surprising)?

root@tssn-file-p10[/]# df -T /mnt/zfs-mirror-01
Filesystem Type 1K-blocks Used Available Use% Mounted on
boot-pool/ROOT/22.12.0 zfs 455188736 3162624 452026112 1% /

It looks like the root dataset failed to mount probably because of the sharesmb parameter. It should have been auto-disabled on import.

zfs set sharesmb=off zfs-mirror-01

then
zfs mount zfs-mirror-01

 

[schwartznet]

It was Ubuntu 22.04

root@tssn-file-p10[/]# zfs set sharesmb=off zfs-mirror-01
root@tssn-file-p10[/]# zfs mount zfs-mirror-01
cannot mount 'zfs-mirror-01': 'canmount' property is set to 'off'

 

[schwartznet]

That worked!!!!

I set canmount to on then BOOM its there now!

 

[anodos]

Did you in any way change defaults for ZFS in ubuntu 22.04?

 

[schwartznet]

Im not sure i set it up a year ago but pretty much the only options i turned on that i remember was dedpue

 

[schwartznet]

The dataset error is gone now too

 

[schwartznet]

I do have Validation errors when trying to create any SMB share though

 

[schwartznet]

This fixed that error FYI

zfs destroy -R zfs-mirror-01/ix-applications

 

[anodos]

This fixed that error FYI

zfs destroy -R zfs-mirror-01/ix-applications

You'll probably want to have that dataset somewhere if you intend to use apps (maybe a second zpool).

I have the same problem.
I imported my pool from a previous Ubuntu install.
Interestingly the other pool that came from exactly the same machine can be shared after I figured out, how to mount it into the proper "/mnt" folder.
