When i use umask parameter to mount bucket, ( -o uid=1001 -o gid=1001 -o umask=277), the file and directory permission display 500 (dr-x------, r-x------) from OS , but when i use this user (uid=1001) to create,delete file and directory successful. Normally, umask=277 , don't have write privilege. why i can create and delete?

s3fs version 1.82, fuse version 2.9.2-7,

@nelson-zhong
The creating/deleting files depend on the permissions of the directory storing those files.
That is, when creating "parent/newfile", it depends on the permissions of the "parent" directory.
Please check the permissions of the parent directory of the file you tried to create.
If the parent directory is 500, I think you can not create the file.
If the parent directory is a mount point and you want to change the permissions, you can use the mp_umask option to control it.
