Understanding CIFS Shares on Synology DSM 7.0
CIFS (Common Internet File System) is a protocol used to share files between systems over a network. Synology DSM 7.0 supports CIFS shares, which can be accessed and mounted on other systems to access the shared files. However, sometimes users encounter the error message "notmount (22) Invalid argument" when trying to mount a CIFS share on Synology DSM 7.0.
Replicating the Error
To replicate the error, let's try to mount a CIFS share on Synology DSM 7.0 using the following commands:
sudo mkdir /mnt/ADN_Archives
echo $?
kinit [email protected]
echo $?
sudo mount.cifs //myNAS.myDomain.lan/ADN_Archives /mnt/
The above commands will create a directory named "ADN_Archives" under "/mnt", initiate a Kerberos ticket for authentication, and then mount the CIFS share located at "//myNAS.myDomain.lan/ADN_Archives" to the "/mnt/ADN_Archives" directory.
If the mount command fails, you may see the error message "notmount (22) Invalid argument."
Resolving the Error
The "notmount (22) Invalid argument" error can occur due to various reasons, including incorrect syntax, incorrect permissions, or a problem with the CIFS share itself. Here are some steps you can take to resolve the error:
Check the Syntax
Make sure that the syntax of the mount command is correct. Double-check the share name, the directory where you want to mount the share, and the credentials used for authentication.
Check the Permissions
Make sure that the user running the mount command has the necessary permissions to access the CIFS share. You can check the permissions of the directory where you want to mount the share using the "ls -l" command.
Check the CIFS Share
Make sure that the CIFS share is accessible and configured correctly. You can check the status of the CIFS share by logging in to the Synology DSM and navigating to the "Control Panel" > "File Services" > "CIFS" page.
Use the "vers" Option
You can try using the "vers" option with the mount command to specify the version of the CIFS protocol to use. For example, you can use the following command to mount the CIFS share using version 1.0 of the CIFS protocol:
sudo mount.cifs //myNAS.myDomain.lan/ADN_Archives /mnt/ -o vers=1.0
Use the "sec" Option
You can also try using the "sec" option with the mount command to specify the security mode to use. For example, you can use the following command to mount the CIFS share using the "ntlm" security mode:
sudo mount.cifs //myNAS.myDomain.lan/ADN_Archives /mnt/ -o sec=ntlm
