... these failing syscalls look like the root cause of your problems.
You could try putting some printk() calls in sys_quotactl() in the
kernel to figure out exactly where the error comes from.  I would
guess it is to do with the handling of the "special" parameter, ie.
"/dev/bender/test" above, since this is the only part where the LVM
device file comes into the picture.

cheers.
