Hi,
We are starting to work with Truclusters here in Brazil and we are
trying to understand the utilization of the Distributed Raw Disk.
I'm sorry for the simple questions and thank you in advance.
. Can I define a LSM volume as the distributed raw disk?
. Which kind of application will take advantage of DRD? Databases
Parallel Servers? Advfs file sets?
. If you included Advfs file sets in the previous answer, what is
the meaning for NFS services now?
Thank you for any help,
Miriam

DRDs are Distributed Raw Disks. You can use them wherever you would use
a RAW disk (well, some caution is required).
As you can't build a filesystem on a raw disk, most of your options are
not valid.
Remember that all nodes in a cluster will have full access to this raw
disk, so any database on this will need a way of ensuring that its
updates are self-consistant. OPS does this - I don't know about other
database vendors.

Thank you for your answer. Now it seems obvious but for a moment I got
really confused with this question.
