The error is at the end of the page, where it says that you can
see how
much space is being used using 'df -h', but the problem is that df
can't
actually see the space gain from dedup, it shows how much would be
used
without dedup.
This command (df -h) shows how much allocated and free space is
available on the filesystem. So when you have a dedup ratio 20:1, and
you wrote 20TB, then your df command shows 1TB allocated.
But that is the exact problem I had. df did NOT show 1TB allocated. It
indicated 20TB allocated (yes, in ZFS).
Yes, zpool list shows you the exact Dedup ratio achieved without
additional checking or counting. But this command (as mentioned by
Heitor) will work with ZFS only.
Aligned volumes can be used with external deduplication appliances
where zpool command is unavailable. Then you can quickly check with
the df -h command.
Yes zpool listed all the information properly, both the actually
allocated space and the dedup ratio, and as I said, in ZFS, df is not
showing the correct information (in an Ubuntu 22.04 and ZFS environment).
Thank you,
Roberto
