Hello!
Recently I mounted my Windows Server 2016’s network drive to my Ubuntu server (location /mnt/shares). Then I installed External storages plugin when I accessed my NextCloud webpage. I did the configurations, I can access all the files that I mounted. For some reason when I open the mounted files it keeps giving me "External storage is full, files can not be updated or synced anymore! error. There are 8 GB of files, I increased my NextCloud server’s disk size to 50 GB, that didn’t help.
When I do the df -h command, it gives me (it doesn’t even show 50 GB here even though I increased disk size, maybe I’m just dumb): 
I’ve done some research, can’t figure out why it’s giving me the error.
For mounting network drive to /mnt/shares I used cifs, edited the /etc/fstab file. In web browser I used “Local” option to display the files.
Would love to get rid of the error. Any help is appreciated, thanks!
