Humm, yes, i got this, what i don't get is, for example, an error i get
and which happens when starting heartbeat on the secondary server : here
it is, and my haresources follows it :
-------------------------------------------------------------------------
Starting High-Availability services:
mknod: wrong number of arguments
Try `mknod --help' for more information.
Heartbeat failure [rc=6]. Failed.
heartbeat: 2006/01/09_10:24:07 info: Neither logfile nor logfacility
found.
heartbeat: 2006/01/09_10:24:07 info: Logging defaulting

heartbeat: 2006/01/09_10:24:07 ERROR: Configuration error, heartbeat not

-------------------------------------------------------------------------
/etc/ha.d/haresources:
management drbddisk::drbd-resource-0 \
Filesystem::/dev/drbd0::/share/spool0/data::ext3 \
killnfsd \
nfs-common \
nfs-kernel-server \
sleep::3 \
IPaddr::10.0.1.200/24/eth1
-------------------------------------------------------------------------
this same file works on the primary server, note that "management" is
the hostname of the primary server where "node1" is the name of the
secondary.
so heartbeat doesn't works on my secondary...
I decided to create /share/spool0 on the secondary.
Last question beeing:
On the primary server, /var/lib/nfs is copied on the mounted/shared
partition. and a link is done. I guess on the secondary, i should
delete /var/lib/nfs and create the same link so when it failover, nfs
knows what to do... right ?
Thanks again :)
Pierre.
