Hello
I'm trying to do NFS failover in a test environment with an underlying
OCFS2 filesystem. This is something that's apparently been done before
and certainly HA NFS isn't new.
I've followed several HowTos, all of which seem to suggest pretty much
the same setup, but I seem to get the same problem no matter how I
configure it.
Here's the setup:
2 VMWare VMs (NODE01 and NODE02) running RHEL4 U5 x86_64 with a shared
fibre channel SAN volume. That volume is OCFS2 formatted and mounted as
/data on both hosts.
Each host has 2 interfaces. An external facing 10.0.0.0/24 and an
internal 192.168.100.0/30
Heartbeat is installed on both nodes and configured identically as follows:
=ha.cf=
keepalive 2
deadtime 30
warntime 10
initdead 120
bcast eth0
ucast eth1 192.168.100.1 # Obviously on NODE02 this is 192.168.100.2
auto_failback on
node NODE02 NODE01
ping 10.0.0.133 # this is an unrelated LAN host
respawn hacluster /usr/lib64/heartbeat/ipfail
use_logd yes
crm off
=/ha.cf=
=haresources=
NODE01 10.199.133.90 nfslock nfs_wrapper
=/haresources=
BTW, crm is off because I tried it with it on and got EXACTLY the same
result.
Here's the problem:
Both hosts start up just fine, NODE01 picks up all 3 resources and
everything's roses. If I induce a failure on NODE01, NODE02 correctly
acquires the resources and everything is still roses. HOWEVER, ~30
seconds later NODE02 reboots. Now the odd thing is, it doesn't matter
which is the primary node, or which host has the failure or even which
has the resources, NODE02 always reboots when there's a failure.
Even if the resources are started on NODE02 and NODE01 has a failure
(ie, everything should stay as it is, no failover required) 30 seconds
after the failure NODE02 reboots!!!
I've got NTP syncing the time, so it's not a clock issue, and I've tried
twiddling just about every setting in the config, to no avail.
Any help? Please?
