If the error rate is not zero, you have an increased error rate. In linux, you just do this: sudo /sbin/ifconfig -a | grep errors | grep -v 'errors:0 ' All of my servers right now have error counter = 0 cumulative since last reboot. In solaris, I had to figure out the command once before, but I forget it now. I remember being misled ... Seeing one error counter stay at zero, while another error counter increased. While we were trying to enable LACP, we'd get one error packet per ... I guess every 1Gb or so that traversed the LACP link. This was fatal to ssh connections. So unless you see a nonzero error counter, I'm not sure how to tell you which error counter to check. Sorry I couldn't be more informative on that ... > Could you share what implementations (OS, switch) have you tested and > how it was done ? I would like to try to simulate these issues. I've done this on Dell switches, almost exclusively. I've done it with Linux, Solaris 10u6 x86, and I think one Netapp. So no, I cannot exclude Dell switches as the possible cause. I revisit and reattempt once every few years, always with the same result. I simply do not use LACP anywhere. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
