Webserver warning:Your storage is full, files can not be updated or synced anymore!

Steps to reproduce

1.upgrade ths filesystem to storage users’ files
2.after upgrade,I login the web-server as local user,the web interface shows:Your storage is full, files can not be updated or synced anymore!
3.And I click “settings” ,You are using 1.4 GB of 1.4 GB (100 %),but default quota is 100 GB
4.Then I refreash the brower, which display normal :You are using 1.4 GB of 100 GB (1.37 %)
5.after a few minuters ,When I login as the same user, the warning about Your storage is full occurs
but desktop client can use normally.
So I don’t know how to solve it, could you give me some suggestion?
thank you.

Sounds interesting, but where is the meat?
Sorry, but without any information about your environment, it’s impossible to say anything. And for pure guessing, I don’t have any time.

Sorry , Maybe I have solved this problem.
We change the mount type of filesystem, and it words well
