\section{Accessing USB storage devices} |
| 1484 |
|
|
| 1485 |
|
Many routers now ship with USB onboard, which makes them fine for dealing as a |
| 1486 |
|
fileserver. If you have such a device and want to setup your own low--cost NAS, |
| 1487 |
|
follow the instructions below. |
| 1488 |
|
|
| 1489 |
|
\subsection{Firmware image preparation} |
| 1490 |
|
|
| 1491 |
|
What you need is: |
| 1492 |
|
\begin{itemize} |
| 1493 |
|
\item kernel support for \code{usb-storage} |
| 1494 |
|
\item kernel support for the filesystem(s) to be used, e.g. \code{xfs} |
| 1495 |
|
\item optionally: \app{lsusb} to check for attached devices |
| 1496 |
|
\end{itemize} |
| 1497 |
|
|
| 1498 |
|
When all prerequisites are met, all that has to be done is to connect the USB |
| 1499 |
|
mass storage device to the USB port of the router. FreeWRT provides a |
| 1500 |
|
hotplugging script which mounts all connected partitions under |
| 1501 |
|
\file{/mnt/discN\_Y} while \code{N} is the index of the connected disk (i.e. |
| 1502 |
|
starting with 0) and \code{Y} is the number of the partition on the disk (i.e. |
| 1503 |
|
starting with 1). |
| 1504 |
|
|
| 1505 |
|
\subsection{Sharing storage via NFS} |
| 1506 |
|
|
| 1507 |
|
There are two implementations available, one residing in kernel space and |
| 1508 |
|
another one implemented purely in user space. If you wish to use the user space |
| 1509 |
|
implementation of NFS, just enable \app{nfs-server}. To use the kernel |
| 1510 |
|
implementation of NFS, activate \app{nfs-utils} for your target. Although |
| 1511 |
|
kernel space is somewhat faster, this implementation has the drawback that only |
| 1512 |
|
directory structures within a single mount point can be exported. So you have |
| 1513 |
|
to supply at least a single entry for each mounted partition in |
| 1514 |
|
\file{/etc/exports}. (Using the user space \app{nfsd}, you can also export the |
| 1515 |
|
complete \file{/mnt} directory. |
| 1516 |
|
|
| 1517 |
|
\begin{Verbatim}[label=sample /etc/exports] |
| 1518 |
|
/mnt/disc0_1 *(ro,no_root_squash,insecure,no_subtree_check) |
| 1519 |
|
/mnt/disc0_2 *(rw,root_squash,insecure,no_subtree_check) |
| 1520 |
|
\end{Verbatim} |
| 1521 |
|
|
| 1522 |
|
Finally, start \app{portmap} and \app{knfsd} (\app{nfsd} when using the user |
| 1523 |
|
space implementation): |
| 1524 |
|
\begin{Verbatim}[label=starting the daemons] |
| 1525 |
|
# /etc/init.d/portmap start |
| 1526 |
|
# /etc/init.d/knfsd start |
| 1527 |
|
\end{Verbatim} |
| 1528 |
