Unable to write file filename: Stale file handle

3 views (last 30 days)
I have a script which generates some data, and at the end of the execution, the data is saved using save command. The script runs smoothly and the data is generated. However when it comes to saving the data, I get the above mentioned error. I have no clue what's happening. Any help would be appreciated.
Update: I ran the same script on my laptop and it works as intended. However if I try to run it on a server I get the same error, even after changing the name of the file I want to save data to. However if I try to append that data to another file, I don't see any errors.

Hello Ruchir,
The issue you are experiencing with the save command, where it works on your laptop but not on a server, could be due to several factors. Here are some possible causes and solutions:
  • File Permissions: Check the permissions of the directory using commands like ls -l (on Unix/Linux) or check the properties (on Windows). Ensure you have write access. You might need to contact the server administrator to change permissions.
  • Path Issues: Use an absolute path for the `save` command to ensure it points to the correct directory. For example:
save('/absolute/path/to/yourfile.mat', 'variableName');
  • Disk Quota: Check your disk usage and quota on the server. You might need to free up space or request a quota increase.
  • MATLAB Version Differences: Ensure the MATLAB versions are compatible. If the server version is older, try using save options compatible with that version.
  • Environment Variables: Check MATLAB's path and environment variables on the server. Ensure they are set up correctly to allow file operations in the desired directories.
  • File System Issues: Ensure the file system is not mounted as read-only. You can check this with system commands (df -h or mount on Unix/Linux).
  • File Locking: Ensure no other processes are using the file or directory. You can use system commands to check for file locks.
I hope it helps!
