Introduction
...
All nodes have a base openSUSE or SLES 15.2 installed.
Install pdsh pdsh on the admin node
| Code Block |
|---|
sudo zypper install pdsh |
...
For example, if one wanted to use node-1 as their admin node, node-2 and node-3 as client nodes, and node-4 and node-5 as their server nodes then these variables would be defined as:
| Code Block |
|---|
ADMIN_NODE=node-1
CLIENT_NODES=node-2, node-3
SERVER_NODES=node-4, node-5
ALL_NODES=$ADMIN_NODE,$CLIENT_NODES,$SERVER_NODES |
...
| Note |
|---|
If a client node is also serving as an admin node then exclude $ADMIN_NODE from the ALL_NODES assignment to prevent duplication, e.g. ALL_NODES=$CLIENT_NODES,$SERVER_NODES |
Set-Up
Please refer here for initial set up which consists of rpm installation, generate and set up certificates, setting up config files, starting servers and agents.
| Note |
|---|
For this quick start, the daos-tests package will need to be installed on the client nodes |
The following applications will be run from a client node:
...
| Code Block |
|---|
SHARED_DIR=<shared dir by all nodes>
export FI_UNIVERSE_SIZE=2048
export OFI_INTERFACE=eth0
export CRT_PHY_ADDR_STR="ofi+sockets"
# selt_test --help for more details on params
#Generate the attach info file (enable SHARED_DIR with perms for sudo to write )
sudo daos_agent -o /etc/daos/daos_agent.yml -l $SHARED_DIR/daos_agent.log dump-attachinfo -o $SHARED_DIR/daos_server.attach_info_tmp
# Run:
self_test --path $SHARED_DIR --group-name daos_server --endpoint 0-1:0 (for 4 servers --endpoint 0-3:0 ranks:tags)
# Sample output:
Adding endpoints:
ranks: 0-1 (# ranks = 2)
tags: 0 (# tags = 1)
Warning: No --master-endpoint specified; using this command line application as the master endpoint
Self Test Parameters:
