Hi there,

It's my first time finding something I can't answer with previous posts, even if I use this forum for a while!


So here's the problem :
Today, I update my FreeNAS 11.0 u4 to the latest 11.1 u4, and when it restarted, I received the following mail:
upload_2018-4-9_16-45-20.png


I was afraid about it (it's used by another team for prod backups), so I rushed my web UI to double check that, and surprise:

upload_2018-4-9_16-53-35.png


Here I don't understand! So my last step was to connect directly on the NAS and go check this Dataset, and here's the output:
upload_2018-4-9_16-56-34.png


It accords with the web UI.


In my understanding, when we created this dataset, we allowed the team to use 700 GiB. They actually use 269/700, so 61% are still available in this dataset.


So as a conclusion, it's not an urgent problem, since I still can use this dataset, but I wasn't able to find anything close to this on the forum or on Google.


Do I need to open a ticket, or anyone has ever issued or can explain this to me?


Thanks a lot!

Hi, thank you for your answer

Here's the output :

Once again, it seems to be OK, but there's maybe something I don't understand.

I'm more concerned about the mail and its cause, since I still can create and remove file in the dataset

If you have any clues,
Thanks again

Well, the GUI is seriously confused, for starters. That 61% used makes no sense - if anything, the dataset is 61% empty.

As for the email, it's naïvely using the "used" property, which is at least as large as "reservation", apparently.

You can work around this by eliminating the reservation, since it's just a bookkeeping thing and doesn't actually affect anything as long as the pool is empty enough.

Ok, it's just the mail (and the GUI as you noticed) that are confused, but nothing that bad finally.

It's quite hard to change this reservation, it's about rules (and probably money) between teams inside, they have 700Go and I haven't any rights about it ...
Anyway, if there's nothing wrong, I'm fine with it, I don't restart the nas everyday

Thank you for your help, it's just little madness we can't explain
A last one, and I let you go :
Do you think I need to open a ticket about this (little and unsignifient) problem ?

I want to see what the new GUI does, first. We can revisit this after 11.2 is out.

Perfect, thank you again for your help =) !

I'm quite sure deleting the reservation is the solution here, so I will mark it as solved =) !
