I asked this question over at StackOverflow and have been advised to better put it in here.
I recently bought a QNAP TS-431K NAS, installed 4 harddisks and set it up as a RAID. Then I configured the network etc. and installed some packages. This works very well, so far. I want to automate some things with Python, but the device resets its internal filesystem on every reboot, so I need to put my Python scripts onto the RAID volume, but in order to start them at bootup, I need to change a certain autorun.sh
, which I cannot access.
According to this QNAP Wiki page (section "All HAL-based Intel and AMD NAS" fits to my case, my OS is QTS 4.5.2) I need to mount a device that is dynamically obtained by the given command (I'll also add the expanded line below) into /tmp/config
. There I would be able to edit the file, but mounting fails. Here the command:
mount $(/sbin/hal_app --get_boot_pd port_id=0)6 /tmp/config
# "$(/sbin/hal_app --get_boot_pd port_id=0)6" expands to "/dev/mtdblock6"
Output:
mount: you must specify the filesystem type
This error is totally reasonable, as -t <type>
is missing in the example. So I tried to find information about the filesystem that is used. The filesystem ext2
from the other examples didn't work. Unfortunately I had no luck, so far, so I listed the available filesystems with cat /etc/filesystems
, which gave me:
ext3
ext2
nodev proc
nodev devpts
iso9660
vfat
msdos
hfs
proc
and devpts
would work in a sense that there is something visible at /tmp/config
, but these are no real filesystems and iso9660
is for optical media. Any other filesystem says:
mount: wrong fs type, bad option, bad superblock on /dev/mtdblock6
...
So then I tried to analyze the device with fdisk -l /dev/mtdblock6
, which said:
Disk /dev/mtdblock6: 15 MB, 15728640 bytes
255 heads, 63 sectors/track, 1 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/mtdblock6 doesn't contain a valid partition table
So I assume, there is nothing there, yet. As there is no such thing as a /dev/mtdblock
without a number or letter at the end, I assume I would have to create a partition table, a partition and an ext2
filesystem on it. I still couldn't figure out what it is with /dev/mtdblock0
through /dev/mtdblock5
.
So my questions are:
- Do I need to format that device under
/dev/mtdblock6
and just add theautorun.sh
? - Is
ext2
here suitable or do I have to use a different filesystem and which one then? - Or am I completely wrong and I should do something completely different? In that case I would appreciate any hint to QNAP documentation etc. I would have missed.
