I am attempting to clone a pool from one thumper to another using zfs send -R | zfs receive -d. To make network transfers a little faster I am using netcat so the entire path looks like: thumper-2 # nc -q 1 -l -p 8023 | zfs receive -vdF tank2 thumper-1 # zfs send -vR tank1 at sent-20080506 | nc thumper-2 8023 The problem is that at some point while sending the zfs send command exits (status 1) with no reason as to why. The zfs receive side just sits waiting for more input. root at thumper-01:~# zfs list -t filesystem -r tank1 | wc 27 135 1818 root at thumper-01:~# zfs list -t volume -r tank1 | wc 6 30 285 root at thumper-01:~# zfs list -t snapshot -r tank1 | wc 88 440 7049 Before exiting 357G of data successfully transferred. Sometimes there is less and sometimes more. Has anyone else seen this or have any suggestions for debugging it? I''m using Nexenta which was built off of b82 sources. Thanks, -Tim
