Question

I’ve tried to configure cluster following through Glassfish clustering tutorials (1, 2), but I’m still having troubles with creating instance in cluster on remote host.
I think it will be better if I give you output with inserted commands, it’ll probably explain more:

adam@adam-desktop:~/Pulpit/glassfish-3.1.1/bin$ ./asadmin
Use "exit" to exit and "help" for online help.

asadmin> create-instance --node adam-laptop --cluster c1 i1
Successfully created instance i1 in the DAS configuration, but failed to create the instance files on node adam-laptop (adam-laptop).

Command failed on node adam-laptop (adam-laptop): Could not contact the DAS running at adam-desktop:4848. This could be because a firewall is blocking the connection back to the DAS or because the DAS host is known by a different name on the instance host adam-laptop. To change the hostname that the DAS uses to identify itself please update the DAS admin HTTP listener address.
Command _create-instance-filesystem failed.

To complete this operation run the following command locally on host adam-laptop from the GlassFish install location /home/adam/Pulpit/glassfish3:

asadmin  --host adam-desktop --port 4848 create-local-instance --node adam-laptop i1
asadmin>

UPDATE

I’m putting hosts file contents and ping command output for sure, that exists connection between adam-desktop and adam-laptop:

  adam@adam-desktop:~$ cat /etc/hosts
  127.0.0.1 localhost
  127.0.1.1 adam-desktop
  192.168.1.101 adam-laptop

  # The following lines are desirable for IPv6 capable hosts
  ::1     ip6-localhost ip6-loopback
  fe00::0 ip6-localnet
  ff00::0 ip6-mcastprefix
  ff02::1 ip6-allnodes
  ff02::2 ip6-allrouters
  adam@adam-desktop:~$ cat /etc/hostname 
  adam-desktop
  adam@adam-desktop:~$ ping adam-laptop

Any help?

Answer 1

It seems that error was caused by entry in /etc/hosts file.

127.0.0.1   localhost
127.0.1.1   adam-desktop
192.168.1.101   adam-laptop

after changing to:

127.0.0.1   localhost
127.0.0.1   adam-desktop
192.168.1.101   adam-laptop

it works. I had to make changes on two machines, it means on adam-desktop and adam-laptop.
