Oracle Linux 6.6
For testing purposes, I am going to create a 2 node RAC cluster (11.2) in Virtual Box. I am using shared disks provided by Virtualbox (not iSCSI). I have already created these disks and shared it. The partitions are visible in both nodes.
I understand that multipath is required only when you have multiple HBA cards (Failover). But, I am doing some testing for multipathing + udev combination to avoid using ASMLib ; hence using native multipathing functionality of Linux.
I have already installed multipath. But, multipath won't work without /etc/multipath.conf file.
# service multipathd start
Starting multipathd daemon: [ OK ]
#
#
#
# multipath -ll
Jul 07 13:01:32 | /etc/multipath.conf does not exist, blacklisting all devices.
Jul 07 13:01:32 | A sample multipath.conf file is located at
Jul 07 13:01:32 | /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf
Jul 07 13:01:32 | You can run /sbin/mpathconf to create or modify /etc/multipath.conf
#
I gather that /etc/multipath.conf is vendor specific (Hitachi, EMC,..etc). But virtualbox is the vendor in this case
A sample /etc/multipath.conf is provided as shown above ( /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf )
Is this enough ? If not, where can i get a sample which is specific to VirtualBox's shared disk feature ?
