Hi,
I am trying to use heartbeat to manage one virtual IP address accros two hosts
which are interconnected only via the normal network. Configuration files are
included in the end of this post.
My problem is that gratious ARP is not always sent when the IP address is moved
between the hosts, resulting in the other equipment being unable to connect to
the virtual IP, even though it is available.
I do the following:
* Initially the IP address is located on the slave host (deb-hp-mla-hlrtest). I
assume the same would happen if it started on the master, but have not tried
that.
* I disconnect ethernet to the slave host
* The IP address is moved to the master host, which broadcasts some gratious
ARP. Everything work fine after 10 seconds.
* I reconnect the slave host.
* The master host detect this:
Nov 7 10:12:08 localhost heartbeat[20683]: WARN: Cluster node deb-hp-mla-hlrtest returning
after partition.
Nov 7 10:12:08 localhost heartbeat[20683]: WARN: Deadtime value may be too
small.
and then it heartbeat restarts
* The slave hosts never released the virtual IP, so it is running as before,
and since heartbeat restarted on the master host, it is the only host with the
IP address.
Nov 7 10:12:07 localhost ipfail[4431]: info: Link Status update: Link nw/nw
now
has status up
* And everything looks ok, BUT no gratious ARP are sent! So my other equipment
still thinks the IP address is at the master host, and cannot connect until
they time out their ARP table.
Am I doing something wrong? I realize the problem could probably be fixed by
using a serial interconnect, but the 2 hosts may not be located the same place.
The easiest for me would be if a host always send gratious arp after the link
has been down.
I am using version 1.2.3 on Debian 3.1 (Sarge)
On 1.2.3, that "returning after partition" should cause both sides to
shut down all resources and restart them. Restarting them should issue
more gratuitous ARPs.
Do both servers get the "returning after partition" message?
