That's a good idea. Take a look at the log snippet below. ipvsadm is
failing to add the entry for the FTP virtual servers. Whay might that
be?

Hi,
One thing I did when I had problems was to run ldirectord without
heartbeat.
This might temporarily remove your problems with heartbeat, so you can
have a closer look at the problem with logging into ftp. They appear to
be separate problems. I ran ldirectord with the command:
/usr/sbin/ldirectord -d start
This would run ldirectord in debug mode, and it would output all its
logging to the screen, so you could see when it issued the ipvsadm
commands to set up ipvs as a load balancer, and you could also see when
you removed or replaced a realserver. You could also stop ldirectord and
the load balancer would continue to work.
Remember heartbeat should be stopped first. You will also need to
manually bring up your VIP. This was the command I used:
ifconfig eth0:0 192.168.0.240 netmask 255.255.255.255 broadcast
192.168.0.255 up
Hope this helps, Jason

Subject: At Startup, I Get This: sed: -e expression #1, char 1:

Hello list,
I am delighted to have gotten heartbeat and ldirectord running. I am now
able to load-balance traffic to two tomcat servers. However, I cannot
get FTP to work at all.
I fired up a sniffer and I can see ldirectord logging into the ftp
server and downloading the welcome.msg file, and I know the file
contains the right data, but for some reason ldirectord will not enable
the FTP virtual server. I've tried looking in ldirectord.log, but there
is no such file anywhere on my system (and I do not have a
syslog_facility enabled.)
I tried adding the --debug option to haresources, like this:
cluster1.nvipa.com \
LVSSyncDaemonSwap::master \
ldirectord::--debug::ldirectord.cf \
IPaddr2::192.168.5.100/24/eth0 \
IPaddr2::192.168.10.100/24/eth1
When I do that, I get additional logging DEBUG2 information in ha-debug.
The logging seems to show the FTP server being enabled. However, the
virtual IP address 192.168.5.100 does not get enabled. When I try to
stop heartbeat, it hangs forever and I have to do a hardware reset. When
it boots back up, heartbeat will not work until I take the --debug
parameter out of haresources and manually re-create /dev/watchdog. After
I do that, I can restart heartbeat and everything goes back to "normal,"
i.e., ldirectord virtualizes tomcat but not FTP.
I also get a couple of "unknown command" errors in ha-debug (see log
snippet below).
