After deleting files, volume free space remains the same.

The most likely cause of this is the checkpoint feature. Checkpoints store deleted and changed data for a defined period of time so that customers can retrieve deleted files and prior versions for data security. This means that the data is not removed from disk until the checkpoint is expired, a maximum of two weeks. If you are deleting data to free disk space, it will be necessary to remove or disable checkpoints.

Can’t delete a file.

If a file cannot be deleted, the first thing to check is security. Make sure that the deleting user has the appropriate rights. Files can also be deleted from the command line. For details on this procedure.

In some cases, a “file not found” message will be generated when attempting to delete a file, even from the command line. Usually, this is due to an invalid character in the filename that cannot be parsed. To delete such a file, use the “\” character. Use any of the command line utilities, and proceed the illegal character with “\”. An example of an illegal character would be a colon, a comma or a double quote.

An exception to this is the “$” character in a filename. In this case, the character must be preceded with another “$” in order for it to be accessible via command line operations.

There is one more item to be aware of when referencing filenames at the CLI. If the filename contains one or more spaces, the entire argument must be enclosed in quotes.

Example: del “/vol1/sales/my big file name”

Can’t delete files from /etc directory.

This is by design as many of these files are required for proper system operations. There may some times that files must be deleted, especially when configuring host files and user files manually. To enable deletion of files from the etc directory the immutable bet must be set.

From the command line type in “cleari /voname/etc/”

Now files can be deleted. Caution must be exercised it is not recommended to delete files from the etc.

5310 NAS specifications

Sun Microsystems, known for its innovative computing solutions, launched the Sun 5310 Network Attached Storage (NAS) system, which marked a significant advancement in the realm of storage solutions in the early 2000s. The 5310 NAS was designed to provide high-performance, reliable, and scalable storage tailored for enterprise environments.

One of the standout features of the Sun 5310 NAS is its file-serving capabilities, which support multiple protocols, notably NFS (Network File System) and CIFS (Common Internet File System). This dual-protocol support allowed organizations to seamlessly integrate the NAS into diverse IT ecosystems, facilitating interoperability between UNIX, Linux, and Windows systems. The enhanced file-sharing capabilities made it an ideal solution for businesses with mixed operating environments.

The Sun 5310 NAS incorporates cutting-edge technologies to ensure high availability and data integrity. The system utilized a RAID (Redundant Array of Independent Disks) technology, providing various RAID levels to protect against data loss while optimizing performance. Additionally, the device featured hot-swappable drives, enabling maintenance and upgrades with minimal downtime, a crucial factor for business continuity.

Equipped with advanced management software, the Sun 5310 NAS offered users an intuitive interface for monitoring storage health and performance. This software included comprehensive reporting functionalities that allowed IT administrators to oversee usage patterns and capacity planning efficiently.

Scalability was another defining characteristic of the Sun 5310 NAS. The system could easily expand with additional storage modules, accommodating the growing needs of an organization without the necessity for complete system overhauls. This flexibility ensured that businesses could adapt their storage solutions to meet evolving data storage needs without incurring significant costs or disruptions.

In terms of performance, the Sun 5310 NAS featured high I/O throughput achieved through its robust hardware architecture and optimized file serving capabilities. This performance baseline was crucial for organizations that relied on heavy data workloads and required rapid access to information.

In summary, the Sun 5310 NAS from Sun Microsystems embodied a forward-thinking approach to network storage, blending reliability, scalability, and multi-protocol support. Its user-friendly management software, combined with the robustness of RAID technology and hot-swappable drives, made it a preferred choice for enterprises looking to streamline their storage infrastructure while safeguarding critical data.
