Failure to Write Data to a CIFS Share

Publication Date:  2013-05-04 Views:  86 Downloads:  0
Issue Description
A CIFS share cannot be written. On the CLI, the command output indicates that the permission for the file system is dr--r--r--.
Alarm Information
None
Handling Process
Step 1 Log in to the CLI of the clustered NAS storage system by using the console IP address.
Step 2 Find the shared filesystem.
1. Run the su - master.
2. Run the cifs.
3. Run the share show share_name to find the shared filesystem.
fs_01 is the shared filesystem.
CIFS> share show share01
ShareName FileSystem ShareOptions
share01 fs_01 ro,noguest,oplocks,no_full_acl,inherit permissions=yes
4. Run the exit.
5. Run the logout.
Step 3 Repair the filesystem.
1. Run the cd /vx.
2. Run the l command to list existing file systems.
Record the name of the file system that is shared by users but cannot be written, where the CIFS share resides.
3. Run the chmod 777 fsname command to grant the read, write and execution permission for the file system.
fsname indicates the name of the file system that is shared by users but cannot be written, where the CIFS share resides.
4. Run the l command and check whether the permission for the fsname file system is changed to drwxrwxrwx.
 If yes, go to Step 4.
 If no, contact Huawei technical support.
Step 4 Map the CIFS share as a network drive again. Then, check whether the fault is rectified.
 If yes, no further action is required.
 If no, contact Huawei technical support.
----End
Root Cause
Users or user groups are not authorized to write data to the file system where the CIFS share resides.
