-Commands:
---node node_name
- Node_name by itself it will create a new node. When used with other
- commands it specifies the node to modify
-
---net hostname nettype [port, recv_buf, send_buf]
- Nettype is either tcp, elan, or gm.
- Requires a node argument
-
---lov lov_name [mdc_name stripe_sz stripe_off pattern]
- Creates a logical volume
- When used with other commands, it specifics the lov to modify
-
---mds device [size]
- Create a MDS using the device
- Requires --node
-
---mdc mdc_name
- Configures a MDC for a node.
- Requires --node
-
---ost device [size]
- Creates an OBD/OST/OSC configuration triplet for a new device.
- When used on "host", the device will be initialized and the OST
- will be enabled. On client nodes, the OSC will be avaiable.
- Requires --node
- If --lov lov_name is used, this device is added to lov.
-
---mtpt /mnt/point mdc_name lov_name|osc_name
- Creates a client mount point.
- Requires --node
-
-Options:
---merge="xml file" Add the new objects to an existing file
---format Format the partitions if unformated
---reformat Reformat partitions (this should be an lconf arg,
- I think)
