RSYNC is a utility software application used in Unix & Linux systems for synchronizing files and directories from one location to another while minimizing data transfer with its unique “delta-transfer” algorithm.
Occasionally, when using RSYNC, you might encounter an error message like this: “rsync error: error in file IO (code 11) at receiver.c(…)” or “write failed”. This message typically signifies that RSYNC ran into a problem while trying to write files to the destination directory.
There are several possible causes for the RSYNC write failed error.
1. Lack of disk space: If the disk you’re writing to does not have enough free space, RSYNC will not be able to perform its operations correctly.
1. File/directory permissions: RSYNC may not have sufficient permissions to write to the destination directory.
1. Network Issues: If you’re using RSYNC over a network, interruptions or instability in the connection could cause this error.
1. Disk Errors: Physical damage or file system corruption on the drive could also be the source of the problem.
Here are a few steps to resolve these issues.
1. Check disk space: Run ‘df -h’ or ‘du’ command in Unix/Linux shell to see your disk usage and ensure that you have adequate space on the destination disk. You can delete unneeded files or move them elsewhere to free up space.
1. Verify permissions: Use ‘ls -l’ command to check directory permissions. If Rsync does not have write access, you can use the ‘chmod’ command to modify directory/file permissions.
1. Network troubleshooting: If you’re using Rsync over a network, you can employ tools like ‘ping’ or ‘traceroute’ to check the network connection. You may also need to consult with your network administrator.
1. Check and repair disk errors: Tools like ‘fsck’ (file system consistency check) in Linux can help identify and fix disk-related errors.
It’s always recommended to check the Rsync man page (‘man rsync’) and other online resources for more detailed guidance. In general, thorough reading and understanding of the command you’re executing will help not only with troubleshooting but also with preventing similar issues from occurring in the future.
