Hi,
I have done the OS clustering in linux redhat 5.6, my one node is down and when i am trying to reboot the other node it is not coming up. any pointer to this would be helpful.
the SAN storage luns are not coming as mounted
so to clarify neither node is coming up? Are you able to comment the relevant lines out in fstab and boot successfully. If so what is the result of trying to manually mount the LUNs?
What do you mean by "the os clustering?" There are dozens of clustering solutions. Care to let us know which one you are using?
Also, you have told us zero about the configuration.
