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)?
