I'm trying to transfer a btrfs snapshot via the network. First attempt: Both NC programs don't exit after the transfer is complete. When I ctrl-C the sending side, the receiving side exits OK.
btrfs subvolume delete /mnt/rec/snapshots/* receive side: # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At subvol 0 sending side: # btrfs send /mnt/send/snapshots/0 | nc -v 127.0.0.1 6790 At subvol /mnt/send/snapshots/0 localhost [127.0.0.1] 6790 (hnmp) open Second attempt: both nc programs exit ok at snapshot 0,1,2, but snapshot3 fails halfway, and 4 fails, as 3 is not complete. receive side: # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At subvol 0 # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At snapshot 1 # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At snapshot 2 # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At snapshot 3 read(net): Connection reset by peer ERROR: short read from stream: expected 49183 read 10450 # nc -l -p 6790 | btrfs receive /mnt/rec/snapshots At snapshot 4 ERROR: cannot find parent subvolume write(stdout): Broken pipe sending side: # btrfs send /mnt/send/snapshots/0 | nc -v -c 127.0.0.1 6790 At subvol /mnt/send/snapshots/0 localhost [127.0.0.1] 6790 (hnmp) open # btrfs send -p /mnt/send/snapshots/0 /mnt/send/snapshots/1 | nc -v -c 127.0.0.1 6790 At subvol /mnt/send/snapshots/1 localhost [127.0.0.1] 6790 (hnmp) open # btrfs send -p /mnt/send/snapshots/1 /mnt/send/snapshots/2 | nc -v -c 127.0.0.1 6790 At subvol /mnt/send/snapshots/2 localhost [127.0.0.1] 6790 (hnmp) open # btrfs send -p /mnt/send/snapshots/2 /mnt/send/snapshots/3 | nc -v -c 127.0.0.1 6790 At subvol /mnt/send/snapshots/3 localhost [127.0.0.1] 6790 (hnmp) open # btrfs send -p /mnt/send/snapshots/3 /mnt/send/snapshots/4 | nc -v -c 127.0.0.1 6790 At subvol /mnt/send/snapshots/4 localhost [127.0.0.1] 6790 (hnmp) open write(net): Connection reset by peer --- Take your mailboxes with you.
