1.7.3

• Added the ability to persist resource roles (persist-role)

• Added one-way replication (target-only) feature

1.7.2

• Added alias functionality for hostname

1.7

• Added forced dump collection feature

• Added log storage path change function

• Add new-current-uuid --no-rotate-bitmap command option

• Displayed in status when SB occurs

• Check kernel version during installation Minor scope expansion

• Added accelbuf-size option (enabled by default), improving replication performance for replicated data below 4K.

• Event Improvements

  • When changing status, add option (--diff) to output the previous status and the status after change.

  • Added synchronization progress event output option (--sync)

  • Added sync event output cycle setting option (--interval)

  • Add json format event output option

  • sync-target-primary event output

• Change c-max-rate default value to 6.5MB

• Changed the invalidate command to only operate when connected.

• [Windows] Changed to automatic meta disk wipe-md processing when /release_vol is performed on the target node.

• Version notation changed to 4 digits

• Changed handling of --discard-my-data connection command -> returns error if not in SB situation

• Changed to automatic SB resolution upon reconnection during SB resolution synchronization.

• Removed meta version upgrade support option during drbd metadisk migration.

1.6.3

• Change property disable_write_same to enable by default.

• Support Ubuntu22, Rocky 9.

• Support Windows/Linux mixed replication configurations.

• Performance Monitor's lookup method has been improved to allow specifying date and time.

1.6.2

• Added packet count-based replication congestion detection. Specify a packet count via congestion-highwater to detect congestion beyond that count. It is enabled by default.

• Added resync-ratio option to specify the synchronization ratio.

1.6.1

• Adds the performance monitor (bsrmon) feature.

• Do not perform kernel module unloading on Linux service termination. From now on, service and kernel module loading/unloading are performed independently.

1.6

• Add support for fast synchronization of only the used area of the filesystem (FastSync) on Linux.

• svc-auto-up, svc-auto-down options moved to node section.

• Made read I/O for BSR volumes to be bypassed without processing.

• Improved volume GUID notation in Windows resource configuration.

• The tcp-cork setting has been disabled by default.

• Enabling this setting could cause performance issues due to packet processing delays.

• The disk-flush setting has been disabled.

• Depending on the disk device, there may be a (severe) delay in the flush operation. This issue cannot be handled by BSR, so it is avoided by disabling this setting.
