This article provides guidance for troubleshooting common BoostFS issues, including connectivity, mount failures, lockbox problems, performance concerns, and compatibility validation. It also outlines recommended checks, log collection locations, and information to gather when investigating BoostFS-related issues.

A user was unable to write to a BoostFS-mounted storage unit after directory ownership was changed from a user-owned group to a shared operations group. Investigation confirmed the behavior is expected because BoostFS authorization checks rely on the user's primary group, unlike some NFS configurations where mount-point permissions may allow broader write access.

This guide explains what Dial Home is on Data Domain systems, what data it sends to Dell, and how each connection method and report type works. Expectations are set for how these automated reports speed issue detection, simplify support, and improve system‑health visibility.

Data Domain claims to need a replication license for a local copy operation which has never historically required one.

Token-based authentication in DD Boost OST Plug-in 8.4 provides a more reliable authentication method and helps avoid intermittent credential decryption issues seen with earlier authentication handling in some NetBackup 10.x environments. It also improves credential security by eliminating dependence on encrypted password decryption workflows.

This article outlines how to fix the issue and reenable the file system when the Data Domain File System (DDFS) panics with the following PANIC string: PANIC: ddr/dm/dmbt_iface.c: dmbt_update_entry_nolock

A BoostFS lockbox may become corrupted after Windows patch installation and a subsequent system reboot, causing BoostFS mount and lockbox query operations to fail. Recreating the lockbox temporarily restores functionality, but the issue can reoccur unless Windows patching and reboot activities are completed before BoostFS installation.

A NetBackup LSU (Logical Storage Unit) or Disk Volume configured through the Data Domain OST plugin may be marked offline when a single DDBoost storage unit has more than five associations configured in the same replication direction. This limitation can cause backup, replication, and disk polling operations to fail, resulting in the associated Disk Volume and Disk Pool being reported as down.

Auto Image Replication (AIR) imports were intermittently missing because multiple NetBackup domains were configured to access the same Data Domain storage units using shared DDBoost credentials. This created an event-stealing race condition where unintended media servers consumed AIR event files, resulting in inconsistent imports and failed restores during disaster recovery testing.

A Data Domain system generated excessive Priority Flow Control (PFC) packets during Avamar swing node replication activities, causing connected Cisco Nexus switches to automatically disable network interfaces. The issue was traced to Intel NIC firmware-level LLDP behavior affecting DCBx communications and was resolved by upgrading to DDOS 8.4 or later.

When a DDOS upgrade is performed on version 8.7 or earlier, the RPM signature check may fail with the error message: "RPM ".rpm file" signature is invalid."

This article outlines the process for generating a Technical Support Report (TSR) log (also known as a SupportAssist bundle), on PowerProtect Data Domain platforms. These logs are essential for Support to diagnose and resolve various system-related issues.

NetWorker: Clone fails with Err: 5009-nfs filecopy stop failed (nfs: I/O error) after Data Domain upgrade to DDOS 8.7 or 8.8

This article explains the process for using a new encryption key.

After upgrading to DDOS 8.6, a Data Domain appliance may be unable to configure or reconfigure a network interface. Affected interfaces may display the FEC value as N/A, and configuration attempts may fail with the error "Failed to set link parameters".

The /ddvar (also known as /ddr/var) filesystem is the primary location that DDOS uses to store logs. This knowledge base article describes the common causes and steps to take to help alleviate or free up space inside /ddvar

Applies To: Any Supported DD model, with DS60 enclosures attached. Description Of The Issue: A Data Domain system experienced a filesystem outage after one power distribution unit (PDU) was powered down during a scheduled redundant power interruption. The issue occurred because DS60 storage shelves were incorrectly cabled to PDUs, breaking fault tolerance.

This article provides information regarding the error "DD Retention Lock Compliance Mode is enabled on this system. License modification requires Security Officer credentials and can be performed only using the Command-Line Interface."

When an NFS client mounts an exported PowerProtect DD MTree, a separate mount for the ".snapshot" subdirectory may appear automatically. This article explains the cause and possible consequences.

Data Domain currently supports SMB dialects up to SMB 2.1 and does not support SMB3. Clients configured to require SMB3, including Windows Server 2025 systems with an SMB3-only configuration, will be unable to connect to Data Domain CIFS shares because SMB negotiation cannot be completed.
