Hi all,
I have a two-node LVS configuration that I'm using as a front-end
to a three-node cluster. It works really well for ssh, http, https,
etc. But, when a user tries to use scp to copy a large file or
directory to the cluster, it commonly stalls and doesn't complete. scp
directly to any node of the cluster works fine, either from outside the
network or from inside it. Things only crawl when using scp to go
through the redirectors. Here are the relevant parts of the
configuration file:
service = lvs
primary = xxx.xxx.xxx.30
backup = xxx.xxx.xxx.2
backup_active = 1
heartbeat = 1
heartbeat_port = 539
keepalive = 12
deadtime = 4
debug_level = NONE
network = direct
virtual plato-ssh {
active = 1
address = xxx.xxx.xxx.29 eth0:1
vip_nmask = 255.255.255.0
port = 22
expect = "SSH-2.0"
send = "SSH-2.0-Probe"
use_regex = 0
load_monitor = rup
scheduler = wlc
protocol = tcp
timeout = 60
reentry = 60
quiesce_server = 0
persistent = 600
server node1 {
address = xxx.xxx.xxx.36
active = 1
weight = 20
}
server node2 {
address = xxx.xxx.xxx.34
active = 1
weight = 20
}
server node3 {
address = xxx.xxx.xxx.32
active = 1
weight = 1
}
}
This is with kernel version 2.6.18-164.2.1.el5 and I'm running piranha
version 0.8.4-11.el5. Has anyone seen anything like this before or have
any ideas what I can do to try to debug it?
Thanks!
