How to Fix: Error splicing files when copying from NAS
Error splicing files when copying from NAS in Ubuntu 20.10 with Nemo 4.4.2.
📋 Table of Contents
The error 'Error splicing files when copying from NAS' affects users of Ubuntu 20.10 who are using Nemo file manager to copy files from their Samba/Cifs NAS storage to local drives. This issue is frustrating because it prevents users from easily transferring files between the two storage devices, and it can cause significant delays in file transfers.
The problem persists even after trying various mounting options and configurations, making it a challenging issue to resolve.
⚠️ Common Causes
- The primary root cause of this error is related to the way Nemo handles file copying from Samba/Cifs NAS storage. The issue arises when Nemo encounters an 'Input/output error' while trying to copy files from the NAS, which can be caused by various factors such as network connectivity issues, disk errors, or incorrect file system settings.
- Another possible root cause is related to the way Ubuntu handles large file transfers over Samba/Cifs connections. In some cases, the error may occur due to the limitations of the cifs file system, which can cause issues when transferring files larger than a certain size (in this case, 500MB).
🛠️ Step-by-Step Verified Fixes
Enable verbose logging and check for disk errors
- Step 1: Open a terminal as the root user and run the command `setloguid=0` to enable verbose logging. This will help you gather more detailed information about the error.
- Step 2: Run the command `sudo fsck -t cifs -n /media/NAS\Storage` to check for any disk errors on the NAS storage device. If there are any errors, fix them using the `fsck` command or seek further assistance from a Linux expert.
- Step 3: After fixing any disk errors, try copying files again using Nemo to see if the issue persists.
Check for cifs file system limitations and adjust settings
- Step 1: Run the command `sudo cifs.utils -i` to check the current cifs file system settings. This will help you identify any potential limitations or issues with your current settings.
- Step 2: Adjust the `file_mode` and `dir_mode` settings in your fstab configuration to optimize performance for large file transfers. For example, you can try changing `file_mode=0777` to `file_mode=0666` or adjusting `dir_mode=0777` to `dir_mode=0666`.
- Step 3: After making any necessary adjustments, restart the Nemo file manager and try copying files from the NAS again.
✨ Wrapping Up
To resolve the 'Error splicing files when copying from NAS' issue, you can try enabling verbose logging and checking for disk errors, or check for cifs file system limitations and adjust settings. If none of these methods work, consider seeking further assistance from a Linux expert or exploring alternative file transfer solutions.
