Hi all,
I replaced our Firewire cards and all 4 nodes are running OK. I installed CRS on all 4 nodes fine. I then installed Oracle RDBMS on all 4 nodes OK. Next, I used DBCA to create a database, it almost succussed. It hangs at the last step when try to startup the instance.
To debug it, I re-boot all 4 nodes, and manually run SQL*Plus, it hangs as well. (I double checked the datafiles are created fine on the shared disk)
In the /var/log/message, it has message like:
May 17 11:46:03 melclul11 kernel: ocfs: Removing melclul12 (node 0) from clustered device (8,46)
I thought it might an Oracle limitation. So I disable the crs on two nodes, and YES, I can startup my database fine.
Now, all 4 nodes are running, only two has crs enabled, and a database is running on these two nodes. It is quite clear to me that this is an Oracle limitation, Oracle only allow 2 nodes on Firewire.
My question is, is this limitation configurable? and How?
Thanks in advance.
Han
