Comment 3 for bug 1222847

I'm using EXT and the version of xenserver is the one installed with xenserver-tech-preview-release-0.3.0-0.x86_64 (Xen version 4.2.2-2021.el6 )

# xe sr-list uuid=4362c04b-e140-41f8-bcb5-36eed394576e
uuid ( RO) : 4362c04b-e140-41f8-bcb5-36eed394576e
          name-label ( RW): /var/run/sr-mount/4362c04b-e140-41f8-bcb5-36eed394576e
    name-description ( RW): Files stored in /var/run/sr-mount/4362c04b-e140-41f8-bcb5-36eed394576e
                host ( RO): r421-e2-5
                type ( RO): ext
        content-type ( RO): default

and the filesystem is :

# df -T

/dev/sda3 ext4 51606140 25691052 23293648 53% /

In /var/run/sr-mount/4362c04b-e140-41f8-bcb5-36eed394576 I can see the file created when I try to start the instance:

# ll /var/run/sr-mount/4362c04b-e140-41f8-bcb5-36eed394576e/
