https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209700 Bug ID: 209700 Summary: [iscsi] ctld advertises support for tagged queuing but does not appear to support it Product: Base System Version: 10.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: agrier@poofygoof.com Using NetBSD-7 iscsi initiator to FreeBSD-10.2-RELEASE ctld target fails wi= th check condition, overlapped commands attempted, even though ctld claims tha= t it supports tagged queueing. packet captures available at http://poofygoof.com/~agrier/attic/freebsd_iscsi.cap.bz2 . for comparison, the same client connecting to a smartOS (illumOS/opensolari= s) iSCSI target is at http://poofygoof.com/~agrier/attic/smartos_iscsi.cap.bz2= , which works correctly. current workaround is to add a quirk to the NetBSD initiator for the FreeBSD target to disable tagged queuing support. it is expected that this hurts throughput, since by definition it disables opportunities for pipelining. --=20 You are receiving this mail because: You are the assignee for the bug.=
