NOTE THESE ARE NOT TO BE APPLIED TO 2.0 TESTING, USE THE QUICKSTARTS IN THE 2.0 ON-LINE DOCUMENTATION
Introduction
The purpose of this Quick Start is to provider a user with a set of cmdlines to quickly setup and use DAOS with POSIX on openSUSE/SLES 15.2.
This document covers installation of daos rpms on openSUSE/SLES 15.2 and updating the DAOS configuration files needed by daos servers
The quick start describes how to use dfuse in order to take advantage of daos support for POSIX. The quick start steps users through running benchmarking tools like
ior and mdtest along with some examples of how to move data between a POSIX file system and daos containers (and vise versa) and finally cleaning up your daos setup.
Requirements
The quick start requires a minimum of 1 server with PMEM and SSDs connected via infiniband storage network and 1 client node and 1 admin node without pmem/ssd but on the infiniband storage network.
All nodes have a base openSUSE or SLES 15.2 installed.
Install pdsh on the admin node
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:
CLIENT_NODES=node-2, node-3 SERVER_NODES=node-4, node-5 ALL_NODES=$ADMIN_NODE,$CLIENT_NODES,$SERVER_NODES
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.
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:
"*" Indicates that the cmdline will run internally only; cmdline should be removed for external customers
Run CART selftest
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:
