I have configured an NIS master/slave set up for our environment NIS1 is
the master and NIS2 is the slave server. NIS1 has a shared directory that
will be automounted by the clients of the network. In order to configure
failover mechanism of automount, I have put in place an NIS map file
auto.share which contains
init NIS1,NIS2:/usr1/share/&
I have then replicated the NIS1:/usr1/share/init directory onto NIS2
server using rsync and shared it accross the network using share command.
I have read that automount failover works only for read only file systems.
So I have shared the /usr1/share/init directoriies on both NIS1 and NIS2
as read-only using the -o ro option
share -F nfs -o ro /usr1/share/init
After having done all this, everything worked perfectly as long as both
servers were up and running. To test the fail-over, I shutdown NIS1 while
all clients were active and the unexpected (or was it the expected)
happened:
-all commands on all clients hang ( I guess, the /share/init directory is
in the front of /usr/bin/ /bin in the PATH environment variable)
-users not able to login to the environment because the environment called
from /share/init is not set. ( it gives a prompt after timing out on NFS)
- cannot cd the /share/init it says NFS timed out waiting for NIS1
- it llooks like the NIS failover mechanism worked fine because on booting
NIS1 again, ypwhich now points to NIS2 on all clients
So it looks to me that all my woes are centered around the automount
fail-over mechanism. Did I miss something? Or is it that automount just
doesn;t failover automatically and I have to do something manually to set
it right. I tried to login through the console of a client and ran the
automount with no luck. Any help/pointers will be appreciated and will
summarize. Thanks in advance.
