4.First, select option “N”, “No”. This will allow the database to be checked read- only.

5.If errors are reported, run dbck again as above, and select “Y”, “Yes” to perform the repairs.

Can’t create new DTQ

A DTQ cannot be defined for existing regular directories. A DTQ must be created using StorEdge administration interfaces (telnet, GUI or command-line), which automatically creates a new directory as part of the DTQ setup.

The maximum number of DTQs per volume is 255. If creation of the 256th DTQ on a volume is attempted, the DTQ will not be created, and an error will appear in the system log.

Nested DTQs are supported. This means that a DTQ can be created as a sub- directory of an existing DTQ. The sub directory DTQ must be created from the command line, using the dtq create command.

If an existing DTQ is moved under another DTQ, the moved DTQ will be converted to a regular directory object and its quota record will be removed. The containing DTQ will take account of the moved objects.

Hard links can be created only inside the same DTQ. Creating a hard link between different DTQs is not allowed. There is no limitation for soft (symbolic) links.

Files moved from DTQ to another directory get new time stamps and copy more slowly.

When moving objects into a DTQ, out of a DTQ or between different DTQs, but still within a single file system volume, the operation is treated as if the object had been moved from one volume to another. The StorEdge will perform a copy & delete operation rather than a rename operation. This takes much more time.

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.
