https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229986 --- Comment #2 from Martin Birgmeier <d8zNeCFG@aon.at> --- I just noticed that the same hang happens when trying to stop the ctld. Scenario: - Machine recently upgrade to 11.2, but with https://reviews.freebsd.org/D7= 538 because of excessive swapping - Machine with raidz2 pool with 6 1.5 TB partitions - Machine acts as iSCSI server to remote VirtualBox instances - Run "zpool scrub" on the pool - In another terminal window, gstat is running - Stop the iSCSI server using "service ctld stop" Result: - gstat hangs - "service ctld stop" does not terminate Expected result: - gstat should continue running - "service ctld stop" should return Scenario continued: - Pause the scrub with "zpool scrub -p" Result: - After a few seconds, gstat continues and "service ctld stop" terminates Remark: - Both the VBox client running directly on the machine as well as the ctld serve zvols, so maybe it is related to that. --=20 You are receiving this mail because: You are the assignee for the bug.=
