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.

  • No labels
