Missing files / data

[RHead]

Hi.

Something strange happened after upgrade kernel and boot. Before that everything worked out now all files are missing but zfs still says that space is still used. Also storage disk ids are odd.
When looking directories of /data there is empy.

Please check if it is mounted:

zfs list -t filesystem -o space,mounted

And please post text, not images of text and format with CODE tags.
