I took a slightly different approach and it works well so far... First you need an initrd with the gluster executables and libraries, which I make and update with this script: #!/bin/bash # PATH=/bin:/sbin:/usr/bin # TROOT=/root/initrd_root # # Update executables for i in `find /sbin -iname "*gluster*"` do cp -vf $i $TROOT/bin/ done # Update libraries for i in `find /lib -iname "*gluster*"` do cp -vf $i $TROOT/lib/ done # Rsync lib dir rsync -av /lib/glusterfs/* $TROOT/lib/glusterfs/ # exit 0 Then you put everything else you need in the initrd and tar it up / compress it, boot it, and have it modprobe fuse and glusterfs -f /somefile_in_initrd /some_local_dir. What I do first though, is have init build a few partitions in ram and format them ext2, then mount glusterfs and copy some common stuff into the ramdisks (which are really the root, not gluster) and create symlinks to the subdirectories in the glusterfs filesystem. And this seems to run Centos no problem... Gluster guys, any comments on a better way to do this? It works great, but I imagine it could optimized for speed...

We are using openqrm as deployment/management system for our servers here. With openqrm we can deploy both native machines and e.g. xen images. As root Filesystem we are currently using NFS which isn't really fast. Because we're using glusterfs for our backups and also for our Samba/NFS Server it is close to use it also as root filesystem for our xen images. I think the only thing we need is fuse in a initrd and the glusterfs binary with the needed shared object files. Any helpful suggestions?
