Hi folks, I'm having (as the title suggests) a problem with zfs send/receive. Command line is like this : pfexec zfs send -Rp tank/t...@snapshot | ssh remotehost pfexec zfs recv -v -F -d tank This works like a charm as long as the snapshot is small enough. When it gets too big (meaning somewhere between 17G and 900G), I get ssh errors (can't read from remote host). I tried various encryption options (the fastest being in my case arcfour) with no better results. I tried to setup a script to insert dd on the sending and receiving side to buffer the flow, still read errors. I tried with mbuffer (which gives better performance), it didn't get better. Today I tried with netcat (and mbuffer) and I got better throughput, but it failed at 269GB transferred. The two machines are connected to the switch with 2x1GbE (Intel) joined together with LACP. The switch logs show no errors on the ports. kstat -p | grep e1000g shows one recv error on the sending side. I can't find anything in the logs which could give me a clue about what's happening. I'm running build 131. If anyone has the slightest clue of where I could look or what I could do to pinpoint/solve the problem, I'd be very gratefull if (s)he could share it with me. Thanks and have a nice evening. Arnaud |
