dc 3,62T
dc2 1,81T
zroot 1,80T
Total amount: 7,23T

Can you post the output of the command zpool list -p on your system?

root@vladiom:~ # zpool list -p

Thanks - can you also post the output of the mount command?

Update to 1.791.

Webmin still show:
Local disk space: 3.37 TB used, 5.27 TB total.

Real local disk space: 8 TB.

What does zpool list -p output on this system?

Also, are all three pools used by mounted filesystems?

[w@sp]

Yes.

[Jamie Cameron]

I'm totally mystified - based on your files and the Webmin code, it should be showing the full 8 TB of disk.

[w@sp]

I know, but the reality is another :(

[Jamie Cameron]

Any chance I could login to this system to see what's going on? I don't have a BSD system with ZFS to test on.

[w@sp]

No, this is a production server.
If you need more information, I am ready to provide it.

Updated webmin:

root@vladiom:~ # pkg version -v | grep webmin
webmin-1.800 = up-to-date with index

The problem is still present ...
