PowerScale OneFS

This document highlights minimum, recommended, and latest code versions for Dell Technologies Enterprise and Datacenter Infrastructure products. We carefully evaluate and monitor code deployment data to ensure that product releases meet our stringent expectations to provide our customers with reliable products and solutions.

This article provides information about supported patches and service releases for OneFS and the HealthCheck system.

Any repurposed nodes should be reset to factory settings before they are added to an existing cluster. Otherwise, previous configurations with overlapping backend IP addresses may cause cluster issues.

The PowerScale Scale-out NAS uses Dell Networking Ethernet switches to provide the network. Dell Networking OS9 and the new OS10 Enterprise Edition (OS10EE) are used in the examples in this document. PowerScale, NAS, Network, Networking, OS9, OS10, OS10EE, switch.

Sometimes a replacement drive can become stuck in the USED state, and further attempts to format or add the drive will return no error but not actually format or add the drive either.

The OneFS event 'Physical Memory low (expected xxxGB, found yyyGB)' indicates either a defective DIMM module in the node, or a problem with the node's configuration.

When adding a replacement drive to a node, the add operation may fail with the message "The add operation failed. An unrecognized drive was found in bay <#>. To format this drive and add it to the file system, run 'isi devices -a format' on this drive and follow the instructions provided."

On OneFS 8.0, the firmware update process will fail if the BMC/CMC subsystem is unresponsive. Sometimes the warning event to indicate this condition is not generated.

Many OneFS versions have obsolete timeout values configured for the drive stall timer. Increasing these values can help prevent unnecessary drive stall events.

Isilon GEN 6: HW_INFINITY_COMPUTE_FAULT: Compute node fault detected (User Correctable) - Event ID: 900160003

Gen6 node fails to boot during the PSI configuration phase, showing the 'isi_upgrade_hardware' script running followed by an error message stating 'Unable to perform receipt update for Hardware Upgrade'.

While trying to configure IPMI on a cluster containing Gen6 nodes, 'isi ipmi features list' returns an empty feature list and no IPMI features can be enabled.

PowerScale Info Hub for OneFS 9.13.0.0 documentation

NetWorker Snapshot Management (NSM) backups may fail with Error relinking snapvx snapshot to target: Unable to perform action Link on SnapVX snapshot, error SYMAPI_C_ACCESS_DENIED.

Network File System (NFS) clients report touch: setting times errors when writing to ACL-governed directories, though the file appears afterward. The issue often occurs after migrations from other storage vendors to PowerScale and affects both NFSv3 and NFSv4.

Unable to send CELOG email events if using Simple Mail Transfer Protocol (SMTP) Port 25 in email settings or an Event Channel.

Anti-virus scan report disappears every day after an upgrade to version 9.5 or later. Impacted report types include SCAN_ON_OPEN and SCAN_ON_CLOSE.

Oplock leases were added to SMB version 2.1 to improve performance and reduce network traffic. Certain workflows may work better if oplock leases are disabled.

Clusters on OneFS 9.13.0.1 may experience Data Unavailability. This issue affects clusters containing F710 or F910 node hardware.

This KB article describes instances where a /base partition appears and shows as full. This occurs when looking at the partitions on a PowerScale node, or output from commands such as the df command.

NFS netgroup clients can still connect to PowerScale NFS exports even after LDAP provider is disabled. This configuration continues to work until the nodes of the cluster are rebooted for maintenance or unexpected reasons, causing potential Data Unavailability (DU).

SmartPools or FilePolicy job fails to start with "too many concurrent daemon jobs" when CloudPools policies are defined.

On Isilon OneFS and PowerScale, Swift authentication with NTLMv2 does not work. It does work with NTLMv1. For use of TLS/SSL with NTLM authentication, any system must use NTLMv2. NTLMv1 is older and plain text only. The Swift implementation does not support NTLMv2 presently, and would require substantial rearchitecture to implement. As the third-party Swift utility as an Isilon component is set for end of life and will be removed in a future release, there are no present plans to redesign our platform and modify third-party OpenStack Swift code to support NTLMv2. This article applies to all versions of Isilon OneFS and PowerScale as of and through 9.x and going forward.

Trash directory HealthCheck failure during daily HealthCheck run.

In the case of aggressive or extensive deletes of files on OneFS, it is possible for certain tracking databases to be overwhelmed. However, this should be easy to fix.

JWT and PAPI timeouts may occur with high volumes of web, API, PAPI, and JWT actions on 9.5 and higher PowerScale OneFS. This may present as JWT process coring.

Instructions for gathering a SupportAssist log, also known as a Tech Support Report (TSR)

Upon upgrading OneFS, the isi_avscan_d daemon is consuming CPU, affecting node performance.

Snapshots may remain on a cluster after their expiration period has passed.
