G'Day all,

I'm rebuilding my Lustre cluster again and in doing so I am trying to understand the role of the --servicenode option when creating an OST. There is an example in the doco shown as this:

[root at rh7z-oss1 system]# mkfs.lustre --ost \

>   --fsname demo \

>   --index 0 \

>   --mgsnode 192.168.227.11 at tcp1 \

>   --mgsnode 192.168.227.12 at tcp1 \

>   --servicenode 192.168.227.21 at tcp1 \

>   --servicenode 192.168.227.22 at tcp1 \

>   /dev/dm-3
But its not clear what the service node actually is.

Am I correct in saying the service nodes are the IP's of the two OSS servers that can manage this particular OST (the HA pair)?
