Hi there,
I have two servers set up with drbd, heartbeat and NFS.
They are only talking over the network, there is no serial heartbeat, and
can't be at the moment.
What I'd like to happen is that if either one loses network connectivity
they "sit down and shut up", ie the one which cannot reach, say, the
router, does not try to become the active node; it sends drbd into
standalone, does not mount the drbd filesystem, does not bring up NFS and
does not bring up the floating interface. It has lost network, it should go
into a 'passive' mode and wait for the network to come back.
I tried using 'ping' with "respawn hacluster /usr/lib/heartbeat/ipfail" and
to list a few IP addresses which should be reachable, but this doesn't seem
to do what I want. Rather, when it loses network and cannot ping them it
puts drbd into standalone, mounts the drbd filesystem, starts NFS and
brings up the interface on the floating address... seems a bit wierd to me.
Is there an FAQ or something for this?
If you're using v1 style configuration, then ipfail is the right
thing. Otherwise, you should go with the pingd. See:
I'm using v1.
http://www.linux-ha.org/ipfail
I had read this, which is where I got the idea from.
However, it doesn't seem to be working.
Here is what I have in ha.cf:
logfacility local0
keepalive 100ms
deadping 5
deadtime 30
warntime 10
ucast eth0 10.10.2.26
ucast eth0 10.10.2.27
node drbd-test-1
node drbd-test-2
auto_failback on
ping 10.10.10.1
respawn hacluster /usr/lib/heartbeat/ipfail
Here is what I have in haresources:
drbd-test-1 \
drbddisk::drbdtest \
Filesystem::/dev/drbd0::/data::ext3 \
killnfsd \
nfs-common \
nfs-kernel-server \
Delay::20::0 \
IPaddr::10.10.2.28/16/eth0
If I go onto the node which is currently secondary and take down eth0 it
takes over as primary, mounts drbd0, starts nfs and tries to bring up
the floating IP.
This is the opposite of the behavior I expected to achieve with this config.
Note that this is a /16 network ie 255.255.0.0 so all listed IP
addresses are in the same network space. 10.10.10.1 is the default route
for both nodes.
Both nodes are running on the same Xen dom0 host ie there is no physical
network between them (I can't pull a network cable out to test loss of
connectivity so I use ifdown) and are running Debian Etch.
