Lessfs-1.5.6 now comes with support for forcing the rotation of a replication logfile.
echo 1 >/.lessfs/replication/rotate_replog
It also fixes a recently introduced bug that caused the replication logfile not to rotate after REPLOG_DELAY had expired.
A new feature is that lessfs_stats now shows the compression/deduplication ratio.
Last but not least a bug has been fixed that allows Lessfs IOPS to increase from approx 1000 IOPS to more then 6000 IOPS. This has been measured with Lessfs compiled with Berkeley DB and the databases stored on an Intel X25M SSD.
