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@rh7z-oss1 system]# mkfs.lustre --ost \ > --fsname demo \ > --index 0 \ > --mgsnode 192.168.227.11@tcp1 \ > --mgsnode 192.168.227.12@tcp1 \ > --servicenode 192.168.227.21@tcp1 \ > --servicenode 192.168.227.22@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)? Sid Young
