I'd suggest first double checking that your kernel modules and user space utilities are up to date. If you're running 0.8.0 you can run zpool version to get the version information. Assuming everything is up to date, you should then be able to run zpool set feature@bookmark_v2=enabled tank to enable the feature.

 zpool version not a command for me

 root@prime:~# zpool set feature@bookmark_v2=enabled zpool
 cannot set property for 'zpool': invalid feature 'bookmark_v2'
 root@prime:~#

 root@prime:~# zpool get version zpool
 NAME   PROPERTY  VALUE    SOURCE
 zpool  version   -        default

Then it sounds like your user space utilities haven't been updated the 0.8.0 for some reason and you should reinstall.

Are you talking about zfsutils-linux?

and reinstall as in the server or the utilities; if utilities how would I go about that ( Sorry for the dumb questions) ?

[behlendorf]

I'm a bit confused myself. My understanding is Ubuntu 18.04 only provides packages for the zfs 0.7,x release which does not support encryption, nor the bookmark_v2. So this isn't an error you should be seeing. Did you somehow install a newer version of ZFS from an alternate source?

[MLWALK3R]

Compiled lastest kernel with lasted zfs build. I never had issues in the past up until 8.0

Used this guide

Well, it sounds as if you user space utilities haven't been updated. Try running through the 'Configure, Build, and Install ZFS' steps again from the guide. Perhaps you accidentally didn't run make install? You could also try running the utilities directly form the source tree being installing them, (i.e. ./cmd/zpool/zpool version).

Tried to get it to install but it isn't working, it would use the old version that was installed I have now removed it totally and still can't get it to install via make.

I've used ./zpool in the cmd folder to get boommark enabled.

Do you have specific instructions for installing the utilities?

[MLWALK3R]

I've reinstalled ubuntu, too many issues going on; build ZFS from the 8.0 build rebooted and everythink is working as it should. Thank you for the support
