Hi all,
I have just flatenered my VPS install and installed debian wheezy. Upon first boot I found out that my / partion was only mounting as read-only.
Found this in the logs;
Starting NFS common utilities: statd[ 17.998558] blkfront: barrier: empty write xvda op failed
[ 17.998573] blkfront: xvda: barrier or flush: disabled

After a quick google search [1]. For it to mount as rw you need to disable barrier by setting "barrier=0" in fstab options.
Just for a reference incase anyone finds this to be a problem.
Happy New Year,
Thanks,
Neil
