sudo chmod -R 777 /mnt/nfs

sudo nano /etc/exports

General Options	Description
secure	Requires request originate on secure ports, those less than 1024. This is on by default.
insecure	Turns off the secure option.
ro	Allows only read-only access. This is the default.
rw	Allows read/write access.
sync	Performs all writes when requested. This is the default.
async	Performs all writes when the server is ready.
no_wdelay	Performs writes immediately, not checking to see if they are related.
wdelay	Checks to see if writes are related, and, if so, waits to perform them together. Can degrade performance. This is the default.
hide	Automatically hides an exported directory that is the subdirectory of another exported directory. The subdirectory has to be explicitly mounted to be accessed. Mounting the parent directory does not allow access. This is the default.
no_hide	Does not hide an exported directory that is the subdirectory of another exported directory (opposite of hide). Only works for single hosts and can be unreliable.
subtree_check	Checks parent directories in a file system to validate an exported subdirectory. This is the default.
no_subtree_check	Does not check parent directories in a file system to validate an exported subdirectory.
insecure_locks	Does not require authentication of locking requests. Used for older NFS versions.

User ID Mapping	Description
all_squash	Maps all UIDs and GIDs to the anonymous user. Useful for NFS-exported public FTP directories, news spool directories, and so forth.
no_all_squash	The opposite option to all_squash. This is the default setting.
root_squash	Maps requests from remote root user to the anonymous UID/GID. This is the default.
no_root_squash	Turns off root squashing. Allows the root user to access as the remote root.
anonuid
anongid	Sets explicitly the UID and GID of the anonymous account used for all_squash and root_squash options. The defaults are nobody and nogroup.
