Issue #2759 has been reported by ftigeot. ---------------------------------------- Bug #2759: hammer(8) doesn't respect the timelimit for deduplication http://bugs.dragonflybsd.org/issues/2759
* Author: ftigeot * Status: New * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- Environment: - a storage server with a 20TB /data volume - a dataset potentially deduplication-friendly (protein sequences) - deduplication has been enabled with a 5mn per day timelimit for /data Problem: - hammer(8) is running most of the day, inducing a high background I/O load on the disks - the particular command is "hammer -t 300 dedup" That command is run from the nightly hammer cleanup cron. It starts at 3am an never finishes. A quick test on a brand new hammer volume confirms the -t argument to hammer dedup has no effect. hammer dedup will run forever as long as there is still data to deduplicate. -- You have received this notification because you have either subscribed to it, or are involved in it.
