ocfs and logical volumes

[Tonatiuh]

RHAS 3 and Oracle Cluster Filesystem into a RAC installing environment with 2 servers.

I have configured rsh and rcp succesfully.

I have created PV, VG and several Logical Volumes. I have installed an configured OCFS, but it cannot detect any logical volume.

Any idea?

You probably need a filesystem with mkfs on the logical volume.

Why did you install rsh and rcp? That is like opening a barn door and saying, come and get me.

openssh shipped with the os and does exactly the same thing. Except its secure.1

Check theo oracle cluster filesystem documentation and see if kernel and patching guidelines have been met.

LVM is not cluster aware, it is not recommended to work as expected in an OCFS environment... You would need a volumemanager that is cluster aware (Veritas). Or drop the volume management completley...

Steven,
rsh and rcp services are needed for Oracle Cluster Manager. The network where this services are going to work is a private and isolated network just between the nodes of the cluster so that is not a need to inprove any additional security.

Ryan,
Yes, you are right. I have solved the issue quiting the LVM step and simple partitioning with fdisk and formating this fdisk partition with ocfs.
