repquota /volumename: This lists all quotas for a given volume. The output is formatted to ten columns, as follows:

Column 1: UID/GID or user group name.

Column 2: By default, this appears to be a two line dash. However, if the listed user has exceeded either soft or hard quota, the respective dash turns to a "+"

Column 3: Current disk usage in blocks for this user.

Column 4: Current soft block quota for this user.

Column 5: Current hard block quota for this user.

Column 6: If currently in excess of soft block quota, time remaining in seven day grace period. Field is blank if user is within soft quota.

Column 7: Current disk usage in number of files for this user.

Column 8: Current soft files quota for this user.

Column 9: Current hard files quota for this user.

Column 10: If currently in excess of soft files quota, time remaining in seven day grace period. Field is blank if user is within soft quota.

There is also a totals line at the end of the quota list, showing how many blocks and files exist on the specified volume.

The quotas are assigned by UID and GID. Every file on the Sun StorEdge 5310 NAS has a GID and UID. In the case of Windows users and groups, the UID/GID is assigned by user mapping.

Please note that the user mapping is only functional in NT domain mode. In secure share mode, the UID and GID are set directly on the share in the Sun StorEdge 5310

NAS UI.

One more important note, check the current file or block usage (via the repquota command) before setting quotas. A common mistake is to not realize that the user or group already owns many files, resulting in a quota that is exceeded as soon as it is defined.

How do I set up Directory Tree Quotas (DTQs)?

Directory Tree Quotas are assigned on sub-directory trees within a volume to limit the amount of space and/or the number of files created under each sub-directory. There is no relationship between directory tree quotas and user/group quotas.

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.
