enakai00 / making xattr enbled tmpfs kernel
Last active December 28, 2015 20:39
RHEL6でtmpfsでxattrが使えるようにするやっつけの手順。当然ながら、RH non-supportです。
1. カーネルソース「kernel-2.6.32-358.23.2.el6.src.rpm」を入手する。
2. SPECファイルのパッチをダウンロードする。
# rm -f /tmp/kernel.spec.patch
# wget https://gist.github.com/enakai00/7558519/raw/79c52871e08816ab262beea4e715a6f580011c23/kernel.spec.patch -O /tmp/kernel.spec.patch
3. Kernelパッケージをビルドする

The simplest libgfapi example.
#include <glusterfs/api/glfs.h>
int main (int argc, char** argv) {
glfs_t *fs = NULL;
glfs_fd_t *fd = NULL;
int ret;
char *filename = "filename";
fs = glfs_new ("volume_name");
ret = glfs_set_volfile_server (fs, "tcp", "server_address", 24007);
