2.7.0 Features
This section applies to installations that are upgrading from Release 2.6.0 or earlier.
Release 2.7.0 added three features, also included in this release:
• Persistent statistics for shadow-copy rules after failed runs of the rule,
• enhanced resiliency for shadow-copy runs, and
• improvements to the output for the show active-directory CLI command, to help with diagnosis of
Active-Directory issues.
2.6.0 Features
This section applies to installations that are upgrading from Release 2.4.3 or 2.5.x.
Release 2.6.0 added two features, also included in this release:
• Forest-to-Forest Trusts (Kerberos) – Windows 2003 servers can now support trust relationships
between AD forests. This allows clients in one of the AD forests to access a CIFS service in the other
forest. In Release 2.6.0, the ARX can support these forest-to-forest trusts, allowing clients from a
remote AD forest to authenticate with services in the local AD forest.
• Shadow-Copy Support for CIFS Open Files – By default, a shadow-copy rule blocks any writes
from CIFS clients while it opens a file to copy it. No other client can write to the file or delete it in the
middle of the copy operation. This prevents any corruptions in the shadow-copy of the file. However,
if some other application is already holding the file open for writes before the shadow-copy rule opens
it, the shadow-copy rule cannot open the file with read-only access. In Release 2.6.0, you can use the
optional allow-shared-access command to successfully shadow copy any such open files.
2.5.1 Features
This section applies to installations that are upgrading from Release 2.4.3.
Release 2.5.1 offered these enhancements, also included in this release:
• Forcing a Volume to “Take Ownership” of a Back-End Share – A managed volume can now take
ownership of a filer share that is evidently (but not actually) owned by another managed volume. This
is an option for the CLI command, enable, for a share (in gbl-ns-vol-shr mode); refer to the CLI
documentation for use cases and other details.
• Flexible Naming for CIFS Services – CIFS services now support NT domain names that do not
match their AD domain names. Refer to the documentation for the CLI command, windows-domain
(gbl-gs).
• Performance Enhancements – for removing shares from a managed volume.
• Latency Statistics for Quorum Disks – The CLI command, show redundancy quorum-disk, now
shows latency statistics for the quorum disk. This is useful for anticipating redundancy-related issues.
