I have created a samba share and granted a user permissions to read/write to the folder. It worked fine for several days. But from yesterday it started giving me the error messages while saving any file to the samba share from windows.

The error says that :There is not enough disk space to "save file... access denied"


But I checked the free space on the server. there is enough space available

I got this error in log file of samba
open_fake_file_shared: access_denied to service[SERVICE_NAME]
file[$Extend/$Quota:$Q:$INDEX_ALLOCATION] user[USER_NAME]


can some body help me fix this ?
