orangefs 2.10.0版本特性
orangefs 2.10.0添加了不少功能特性，作为pvfs的分支之一，orangefs是一个优秀的值得研究的并行文件系统，根据链接
可以知道这次的版本更新带了以下特性：
- general updates
- numerous autotools related m4 files are updated.
- code refactored in numerous places to eliminate compiler warnings from new versions of gcc.
- documentation updates.
- Server
- updated formatting to conform to standard in simple-stripe code.
- Clients
- build liborangefs by default. liborangefs provides an orangefs version of posix system calls.
- Windows Client
- Retargeted Client to the user mode file system library “dokany” v1.5.1.1000. (See https://github.com/dokan-dev/dokany)
- Retargeted build to Visual Studio 2022.
- Updated Event Logging for modern versions of Windows.
- Removed obsolete security modes.
- Updated the executable installer to install dokany and necessary Visual C++ runtime libraries.
- Updated OpenSSL.
- Made several quality-of-life improvements.
- bmi
- Eliminated IBV_EVENT_WQ_FATAL warnings
- Added a new RDMA module:
- Utilizes the RDMA Communication Manager library (librdmacm), abstracting transport-specific details out of connection management
- Adds RoCE v2 support to BMI
- Added a new experimental InfiniBand module for future development:
- Still a work in progress and minimally tested
- Current experimental changes include:
- Improved connection-based reference counting
安装过程
这里我使用的环境是fedora38，为什么使用这样一个系统版本，主要原因是在查看官方文档时，发现它对红帽系的支持更好，且2.10.0版本中，5.15.0以上的内核版本似乎提供更好的性能，所以我用了一个较新的系统版本，在生产环境中，应该更推荐almalinux9或者rocky9
我们先安装解决一些包的依赖问题：
sudo dnf update -y
sudo yum -y install gcc flex bison openssl-devel libattr-devel kernel-devel perl make automake
sudo dnf install -y "Development Tools"
然后下载2.10.0 release源码包
wget https://github.com/waltligon/orangefs/releases/download/v.2.10.0/orangefs-2.10.0.tar.gz
准备开始编译，先解压
tar zxf orangefs-2.10.0.tar.gz cd orangefs
生成configure并检查缺少的包
./prepare
执行configure
./configure --prefix=/opt/orangefs --with-kernel=/lib/modules/6.5.5-200.fc38.x86_64/build/ --with-db-backend=lmdb --enable-shared --enable-epoll --enable-racache --enable-ucache --enable-visual
到这一步应该会出现下述报错：
configure: error: The kernel source tree does not appear to be 2.6 or 3.X or 4.X
这个问题我怀疑是configure里面还是指定需要4.*以下的内核版本，我们进去把这部分注释掉，如下述图片这样
安装
make & make install
