nothing. from the 10.04 syslog, I do see this right after all the scsi attach events:
Sep 24 13:54:01 file3 multipathd: sdm: add path (uevent) Sep 24 13:54:02 file3 kernel: [ 7.297268] sd 10:0:0:0: rdac: LUN 0 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.299115] sd 8:0:0:0: rdac: LUN 0 (owned) Sep 24 13:54:02 file3 kernel: [ 7.300844] sd 9:0:0:0: rdac: LUN 0 (owned) Sep 24 13:54:02 file3 kernel: [ 7.302519] sd 10:0:0:1: rdac: LUN 1 (owned) Sep 24 13:54:02 file3 kernel: [ 7.304256] sd 10:0:0:2: rdac: LUN 2 (owned) Sep 24 13:54:02 file3 kernel: [ 7.306406] sd 10:0:0:3: rdac: LUN 3 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.308048] sd 8:0:0:1: rdac: LUN 1 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.309676] sd 9:0:0:1: rdac: LUN 1 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.311221] sd 9:0:0:2: rdac: LUN 2 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.313092] sd 8:0:0:2: rdac: LUN 2 (unowned) Sep 24 13:54:02 file3 kernel: [ 7.314769] sd 9:0:0:3: rdac: LUN 3 (owned) Sep 24 13:54:02 file3 kernel: [ 7.316383] sd 8:0:0:3: rdac: LUN 3 (owned) Sep 24 13:54:02 file3 kernel: [ 7.316388] rdac: device handler registered and similar with the first 12.04 boot, except the "owned/unowned" lines are intermixed with the scsi attaches instead of all at the end, so that's different. as far as active/active, I am seeing 140MB/s writes, so RR is working well enough. I think the MD3000 processor is the bottleneck. it's not renowned for being super fast. I did try adjusting the rr_weight and rr_min_io, but it doens't seems to have changed much. Defaults are working well. I'm not running Jumbo frames yet, so maybe that'll help some. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1057054 Title: poor performance after upgrade to Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1057054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
