New Features and Enhancements The following sections summarize the new features and enhancements in each release. FluidFS Version 6.0.500135 New Features and Enhancements Version 6.0.500135 provides the following new features and enhancements: ● ● ● ● ● Increased the event severity of Active Directory Clock Skew events. Increased the event severity and added the detailed description of 'Partial' or 'No Service' events. Disabled Arcfour cypher for SSH by default Disabled TLS 1.
PAGE 3
Multitenancy Data Access – Access through a VIP enumerates the SMB shares and NFS exports that belong to the tenant and connect to these shares and exports. Each tenant has separate access control settings, including the ability to join the same or separate Active Directory domains.
PAGE 4
NFSv4 Advisory Locks FluidFS NFSv4 supports mandatory byte-range locks. With multitenancy enabled, NAS administrators can configure NFSv4 to switch from mandatory to advisory locks at the tenant level using the CLI. FTP and FTPS User Authentication and Encryption Starting with FluidFS v6, anonymous access to FTP and FTPS is disabled by default. Only authenticated users can log in.
PAGE 5
● CLI> client-access authentication local-groups list Metadata Tiering Metadata tiering provides the ability to store data and metadata in different storage tiers . When creating or expanding a NAS pool, administrators can specify the Storage Center tiers to use for data and metadata. The NAS administrator has the option to optimize the setting for metadata-intensive I/O patterns, which allocates a larger portion of the NAS pool for metadata than the non-optimized setting.
PAGE 6
Area Description System Functionality In rare cases, the system failed to poll the power supply within a short interval and false events would be shown in the event log stating voltage/current problems with a PSU. The polling logic has been improved to prevent false negatives. Data Protection Using NFS4 with Kerberos could cause a file system process to panic. Data Protection PowerShell API does not report accurate replication data. Fields are empty or 0 for the GetDellFluidFsReplication cmdlet.
PAGE 7
Area Description Some applications, such as Novell Storage Manager, requesting to enumerate open files in a given folder or directory (basepath) received faulty results. Changing ownership (chown) of a file using NFS4 did not reflect in space usage (quota). When applications requested to lock a byte-range and to ignore the lock sequence, file locks were not honored when using SMB3. Data Protection Under rare conditions, NDMP backup failed.
PAGE 8
Area Description During a battery calibration cycle, the following alert was falsely generated: BPS on NAS controller X is not operating properly. Battery reports failed state. After a Firmware update to v6, the following event was falsely generated: The forced battery cycle in NAS controller X is no longer required. After a Firmware update to v6, capacity trends and statistics only showed 48 hours of historical data. Fixed Issues in FluidFS Version 6.0.
PAGE 9
Area Description NFSv4 ACL inheritance on UNIX volume did not function properly on subfolders created from SMB clients. Users were unable to set/get ShareLevelPermissions attributes with PowerShell API. Copying using Finder and NFS4 did not work on Mac OSX, but it worked from terminal. NAS pool could not be expanded in system with multiple storage arrays if new size was not divisible by the number of storage arrays.
PAGE 10
Area Description Attempts to create or modify reserved names will be denied. Account Management and Authentication FluidFS shows open files of SMB and NFSv4 protocols only. Open files for NFSv3 are not displayed. If you have a cluster joined to Active Directory and NIS domains, the Domain drop-down list displays the UNIX and Windows user names in different windows. To use Metadata tiering, you must have an even number of Storage Centers.
