SOLVED Actual diskspace and estimated diskspace differ.

Hi people,

I noticed today, that we have some sort of problem with our FreeNAS.
We have rsync tasks, to backup some other machines to FreeNAS. Rsync is configured, to delete files on FreeNAS, that does not exist on the sending side. Everything was running fine for the last few month, but now we have a small issue. (Probably after we upgraded hdds on the remote machines?)

While

Code:

du -hs

shows a reasonable diskusage, the webinterface of FreeNAS shows a growing amount of data everyday.
For example: du= 260GB vs. webinterface= 970GB at the moment.

Does anybody has an idea?

We copy about 60GB every night, so the output of "du" stays almost the same, but weboutput says data is growing exactly by this amount.

du doesn't really understand ZFS snapshots, quotas, etc. zfs list -o space will give you a better idea of what is going on space-wise.

Great! I'm embarrassed: snapshots... ;-)

Snapshots was what came to mind as well when reading the first post. It's a common thing.
