Starting from DSM 6.2, the core replication function is centrally managed by a new package, Replication Service. Packages with replication feature, such as Snapshot Replication, must install the Replication Service package.

DSM 6.2 can only be installed on Synology products running DSM 6.0 and above.

What’s New in DSM 6.2

Daily and monthly reports provide more comprehensive information, allowing IT administrator to review abnormal activity and security scan regularly.

User login details and abnormal geolocation information are dissected using intelligent analysis techniques and reported via DSM notifications.

Btrfs file system is now available on more Synology NAS models utilizing ARM platforms. Enjoy the powerful features of the next-generation file system.

When first creating SHA cluster, user new to SHA can choose to only replicate system configuration to shorten setup time.

Brand new user interface is introduced to display more details of both active server and passive server, giving you an in-depth system utilization overview.

The new interface design provides more detailed and visual information as well as easy-to-follow solutions.

A simpler yet more intuitive user interface, offering you a comprehensive cluster overview and management.

SHA 2.0 can handle situations more effectively especially when the servers are in a vulnerable state.

New mechanism can now eliminate unnecessary system reboot during major update to keep your cluster secure and maintain high service availability.

High Availability Manager has been modularized into a package to ensure better system maintenance and offers greater update flexibility.

Provided an option to change stripe cache size when the RAID type of Storage pool is RAID 5, RAID 6, RAID F1, or SHR (three disks or above).

The health status of disks is now uniform with storage pools and volumes.

After each DSM upgrade, DSM will remind users if a bad sector or lifespan alert is not set up.

Added a default monthly S.M.A.R.T. test on both new and existing drives that were not previously configured.

Users can remotely deactivate drives via Storage Manager for better management.

RAID resync speed can now be adjusted to accommodate IT management needs.

Smart Data Scrubbing detects the supported file system and RAID type to perform data scrubbing automatically while enhancing data scrubbing usability. A new built-in scheduler allows users to do data scrubbing periodically with just a few clicks, improving data integrity and consistency.

Introduced Storage Pool, a new storage component, to replace the original Disk Group and RAID Group, and rearrange storage-related functions to provide users with a more consistent and smoother experience.

The brand new Overview shows the health status of all storage components on your NAS, displaying a clearer and better look on the system overview.

Known Issues & Limitations

Office 2.x and below are not compatible with DSM 6.2.

The original RAID scrubbing scheduled tasks will be migrated to Smart Data Scrubbing scheduled tasks. If the upgrade is performed while running scheduled tasks, the Data Scrubbing process will automatically be re-executed shortly after the upgrade is completed.
