Hi Folks,
I could not find a resolution for this exact issue so I am posting here.

@acd Hello again.

Could you say what version of Rockstor you are experiencing this with.

Note that we don’t currently enforce share sizes so the Web-UI indication of a share size is basically a cosmetic currently. There were early quota maturity issues that have mostly now gone I believe so we can re-address this enforcement in time. But currently we have some more pressing issues that are taking the majority of development time available unfortunately.

You could try, in the mean time, just to have your figures line up. disabling quotas on the associated pool. But again this capability depends on the Rockstor version you are running.

Hope that helps.

Hi Phil, thank you for your quick response. I am trying to setup some monitoring and this is the main reason I want to have a realistic size for the share.
I am running ROCKSTOR 4.1.0-0.
I disabled the quotas and I was able to resize the share, thanks!
