Yesterday I swapped my 100Mb server NICs for new Gbit NICs (RTL-8169). I have been running lucid on 2 machines for about a month, and the last machine was upgraded about 3 months ago. The NIC upgrade was the only thing that changed yesterday. My switches are D-Link DGS-2208 (Gbit).
- When transferring files via NFS3, transfer rates run about 65Mb/s, the *receiving* computer will lock up hard within the first minute. There seems to be no problems with the sending server. This is consistent regardless of which of my three servers are doing the sending or receiving. - In addition to the NFS problems everyone else is reporting here, I also run a DRBD share between two servers, formatted with OCFS2. After one of the machines is rebooted, a DRBD sync is started between servers, and again the *receiving* machine will lock up hard within the first minute. In drbd.conf, I have 'rate 1000M', and transfer speeds were again around 65Mb/s at the time of lockup. Lockup has occurred on the receiver regardless of which server was being brought up. I have changed rate to 500M and will see on the next reboot if their is still a lockup. I think this may show that the problem is not limited to NFS transfers. I was able to get DRBD back in sync by disconnecting the ethernet cable until ubuntu finished booting up, then plugging in the network again. This would lead me to believe that the problem is more likely related to a combination of system load and network load?
