Technical white paper | HP RA for Red Hat Storage Server on HP ProLiant SL4540 Gen8 Server

Confirm that all the storage servers are in connected state using the peer status command:

rhs01 # gluster peer status

A. Create Distribute only volume:

rhs01 # gluster volume create dist2 rhs01:/rhs/brick1/dist2

rhs02:/rhs/brick1/dist2

rhs01 # gluster volume create dist3 rhs01:/rhs/brick1/dist3

rhs02:/rhs/brick1/dist3 rhs03:/rhs/brick1/dist3

rhs01 # gluster volume create dist4 rhs01:/rhs/brick1/dist4

rhs02:/rhs/brick1/dist4 rhs03:/rhs/brick1/dist4

rhs04:/rhs/brick1/dist4

B. Create Replicate volume:

rhs01 # gluster volume create mirror2 replica 2

rhs01:/rhs/brick1/mirror2 rhs02:/rhs/brick1/mirror2

C. Create Distribute-Replicate volume:

rhs01 # gluster volume create mirror4 replica 2

rhs01:/rhs/brick1/mirror4 rhs02:/rhs/brick1/mirror4

rhs03:/rhs/brick1/mirror4 rhs04:/rhs/brick1/mirror4

Mount RHS volumes on client nodes

Mount all the RHS volumes that you created on all the four clients using the following commands:

client01 # mkdir /mnt/dist2 /mnt/dist3 /mnt/dist4 /mnt/mirror2 /mnt/mirror4

client01 # mount -t glusterfs rhs01:/dist2 /mnt/dist2

client01 # mount -t glusterfs rhs01:/dist3 /mnt/dist3

client01 # mount -t glusterfs rhs01:/dist4 /mnt/dist4

client01 # mount -t glusterfs rhs01:/mirror2 /mnt/mirror2

client01 # mount -t glusterfs rhs01:/mirror4 /mnt/mirror4

Repeat these commands on the other three clients.

Note

Even though we are using the same RHS server for mounting the volumes, the Native protocol has built-in load balancing.

The clients use the mount server initially to get the volume information, and after that they will contact the individual

storage servers directly for accessing the data. The data request does not have to go through the mount server.
