Re[2]: [Linux-cluster] some questions about setting up GFS



Hello!

> It looks like you are not using pool.

Thanks, I've guided by your examples, so raid can be mounted.

Now I have some questions about Cluster Configuration System Files.

I have 2 nodes - hp1 and hp2. Any of nodes have Integrated Lights-Out
with ROM Version: 1.55 - 04/16/2004.

Since I have only 2 nodes one of them has to be master, but if first
of them (master) is correctly shut down, slave experiencing
serious problems which can be solved by resetting. Is it all right?
How to make it right?

I tried to make servers = ["hp1","hp2","hp3"] (hp3 is really absent),
then if master is shut down second node became master. So, if
nodes are alternately correctly shut down and boot up master is
switching from one to another and everything seems ok, but if one of
the nodes is shut down incorrectly (e.g. power cord is pulled out of
socket), this have written in systemlog:

If start again service lock_gulm on the second node, then on first
node this have written in systemlog:

Jan 12 14:50:15 hp1 lock_gulmd_core[6500]:  (10.10.0.201:hp2) Cannot login if you are expired.

And I can't umount GFS file system and can't reboot systems
because GFS is mounted, only reset both nodes.

I think I have mistakes in my configuration, may be it is because
incorrect agent = "fence_rib" or something else.

Please help :-)


Cluster Configuration:

cluster.ccs:
cluster {
         name = "cluster"
         lock_gulm {
             servers = ["hp1"]    (or servers = ["hp1,"hp2","hp3"])
         }
}

fence.ccs:
fence_devices {
                ILO-HP1 {
                        agent = "fence_rib"
                        ipaddr = "10.10.0.111"
                        login = "xx"
                        passwd = "xx"
                        }
                ILO-HP2 {
                        agent = "fence_rib"
                        ipaddr = "10.10.0.112"
                        login = "xx"
                        passwd = "xx"
                        }
            }

nodes.ccs:
nodes {
      hp1 {
          ip_interfaces { eth0 = "10.10.0.200" }
          fence { riloe { ILO-HP1 { localport = 17988 } } }
          }
      hp2 {
          ip_interfaces { eth0 = "10.10.0.201" }
          fence { riloe { ILO-HP2 { localport = 17988 } } }
          }
# if 3 nodes in cluster.ccs
#      hp3 {
#          ip_interfaces { eth0 = "10.10.0.201" }
#          fence { riloe { ILO-HP2 { localport = 17988 } } }
#          }



Thanks a lot anyway!
