Hi all, We're seeing the same issues with our ixgbe cards as mentioned in this thread: http://lists.freebsd.org/pipermail/freebsd-bugs/2013-October/054216.html on FreeBSD 9.2-RELEASE. Can anyone tell me if there's a fix out there that I cannot find? -- Met vriendelijke groeten / With kind regards, Johan Kooijman T +31(0) 6 43 44 45 27 F +31(0) 162 82 00 01 E mail at johankooijman.com
This sounds like it might be the issue where large NFS transfers over TSO exceed the maximum number of segments supported by ixgbe (or other drivers). There is a thread on it: http://lists.freebsd.org/pipermail/freebsd-net/2014-January/037694.html Workaround would include: - Disable TSO on the ixgbe port with "ifconfig ix0 -tso". There would be a performance impact on the NFS server. - Decrease rsize/wsize parameters on the ESXi client mounts to 32K or lower. There would be a performance impact on both the NFS server and the clients.
