GlusterFS is a userspace filesystem which can create network mirrors/stripes etc. While I have not fully investigated all the functionality of GlusterFS, this article will get you started fast and fill in the blanks. Doing this process taught me a little something about Linux VServer and its kernel interactions as well. This process is very short in terms of compile but the steps were spread out all over the place.
i686 server CentOS 5 Kernel 126.96.36.199-vs188.8.131.52.1 internal IP 10.10.10.1 +Nat
test01 10.10.10.2 test02 10.10.10.3
Serve a gluster filesystem from test01 to test02
on server first you need the kernel source matching your kernel
yum install kernel-devel
mkdir /usr/local/src/fuse cd /usr/local/src/fuse wget http://ftp.zresearch.com/pub/gluster/glusterfs/fuse/fuse-2.7.3glfs10.tar.gz rpmbuild -ta fuse-2.7.2glfs9.tar.gz rpm -Uvh /usr/src/redhat/RPMS/$(uname -m)/fuse-*rpm rmmod fuse depmod -a modprobe fuse
Copy the device into the guests
This is trick one. guest systems share the kernel so you are not going to be able to install any kernel modules inside the guest.
cp -a /dev/fuse /etc/vservers/test01/vdir/dev cp -a /dev/fuse /etc/vservers/test02/vdir/dev
Create fuse group and ensure proper permissions
vserver test01 enter groupadd -g 102 fuse
