PowerScale OneFS

The Dell PowerScale OneFS Info Hubs provide links to OneFS documentation.

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

This article displays a list of Dell Software Products and related articles on how to obtain the Software Unique ID (SWUID) for each specific product. The SWUID is required for streamlining the processes related to both the Software License Renewal process and opening a Support Case.

This article provides an overview of the PowerScale OneFS upgrade process.

This article is designed for OneFS 8.2.x, 9.5.x and later to provide customers insights about how licensing works, how to apply licenses, and an FAQ.

Server Message Block (SMB) connection and protocol audit may stop working after SMB service is disabled or enabled.

Affected Product: PowerScale OneFS (Releases prior to 9.13) S3 client applications operating against a PowerScale OneFS cluster reports "invalid UTF-8" or XML parsing exceptions when performing `ListObjects` or `ListObjectsV2` (GET Bucket) requests. This issue affects environments where standard ASCII filenames contain special characters, most notably the percent sign (`%`).

Affected Product: OneFS 9.7, 9.13, and earlier S3 `ListObjectsV2` API requests fail with XML parsing errors on the client side. This issue occurs selectively when the requested bucket contains files with names that include invalid character encodings or non-UTF-8 byte sequences. If a client attempts to access one of these specific offending files directly by S3, OneFS will correctly throw a `400(InvalidURI): Path cannot be encoded as UTF-8 string` error. However, during a `ListObjectsV2` directory walk, the API request succeeds with an HTTP 200 OK, but delivers a malformed XML payload that fails the client's parser.

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

An issue where provisioning SupportAssist in PowerScale OneFS and while checking "isi supportassist provision view," the status remains in INCOMING.

Some PowerScale hardware procedures (such as power cycling or power draining a node) vary depending on the hardware generation. The node model name does not clearly indicate the hardware generation. Use the table below to identify your node’s hardware generation and follow the appropriate instructions in related knowledge base articles.

SSH login to newly added PowerScale nodes fails with Active directory credentials, though the authentication provider is online on PowerScale nodes. The same credential working fine on the Web interface login portal

Troubleshoot slow data offload speed to CloudPools target by verifying upload statistics, checking running jobs, and modifying CloudPools file pool policy to skip read-only paths, ensuring files are not skipped and must be sent to the cloud target.

Before the fix, many messages "Can't start NLM - unable to contact NSM" are logged in /var/log/messages.

Upgrading OneFS fails with the error "Hook Failed [/usr/share/upgrade/event-actions/upgrade-post-reboot-final/remove-lsa-nthashes.py]."

SSH File Transfer Protocol (SFTP) fails for nonroot accounts after upgrading OneFS to 9.7.1.0 / 9.10.1.0.

OneFS 9.x clusters with mixed node configuration containing archive nodes can encounter performance issues if the system flag is set on the archive tier.

SK Hynix PE8010 & PE8030 NVMe M.2 drives have been observed to report a PDR3 Event Code and failed status.

It is essential to periodically check the installed firmware package and update to the most recent General Availability (GA) firmware version to enhance system performance. This process ensures that your system operates efficiently with the latest improvements and security updates. Regular maintenance and updates are key to optimal system functionality.

PowerScale node panic reboots intermittently with BUF_TIMELOCK or Journal BTL drain after upgrading to OneFS 9.10.1.7, 9.13.0.1, 9.13.0.2 or 9.13.1.0. Clients could potentially experience latency due to intermittent locking contention with hangdumps.

When cybercrime is at its peak, security is a prime concern and if, there is a plan to monitor cluster statistics, it is recommended to use SNMPv3.

This article discusses the reason for zero window counters from the netstat command. It also discusses possible points of interest while researching and investigating why these values are increasing.

Newly provisioned OneFS 9.13.0.X clusters lack a signed legacy XML license file. This causes upgrade failures to 9.13.1.0 or later because the required /ifs/.ifsvar/isi_license.xml file is missing.

OneFS 9.5 and above includes significant security enhancements that could potentially impact a Server Message Block (SMB) workflow. Clusters not yet on version 9.5 should follow the designated upgrade path in this article. This is to avoid issues that may result from these enhancements in code between versions of OneFS.

Troubleshoot PowerScale OneFS slow performance with a comprehensive guide on network configuration, processing loads, and monitoring with InsightIQ for improved cluster efficiency.

This shows how to choose between displaying available space as cluster size or quota hard threshold.

In a cluster, nodes are configured as peers, meaning they work together to share resources and manage data. If smartfail is failing out nodes, a full /var on one node may block the FlexProtect job and prevent smartfail of another node.

This KB article is useful to troubleshoot Application Programming Interface (API) issues against the cluster directly using curl commands. Use it to rule out issues with custom scripts or application code.
