Hi all, I have a weird situation here where I can't get my head around. One FreeBSD 9.2-STABLE ZFS/NFS box, multiple Linux clients. Once in a while the Linux clients loose their NFS connection: Feb 25 06:24:09 hv3 kernel: nfs: server 10.0.24.1 not responding, timed out Not all boxes, just one out of the cluster. The weird part is that when I try to ping a Linux client from the FreeBSD box, I have between 10 and 30% packetloss - all day long, no specific timeframe. If I ping the Linux clients - no loss. If I ping back from the Linux clients to FBSD box - no loss. The errors I get when pinging a Linux client is this one: ping: sendto: File too large What we already did: - switched interfaces in the FreeBSD box: switched from ixgbe to a gbe interface. Both have the same issue. - After that I configured the ixgbe interface with a different IP & subnet and I'm able to ping without any issue to any client. - Verified MTU's - all default; - Cheched switch config - is empty now, it's as much configured as a fridge :) Any hints on where to search from here? -- 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@johankooijman.com
