DSM-G600, DNS-3xx and NSA-220 Hack Forum

I have read everywhere, searched high and low and tried everything, but I just can't get my USB drive to mount. So, I have my DNS-323 set up as a RAID 1 array. I wanted to upgrade my drives from 1TB each to 2TB's each. Reading the forum it seemed like the easiest way would be to remove my old drives and install the 2 new drives creating my new RAID 1 array, which I did with no problems. I then threw one of the old drives in a USB enclosure and set out to mount it to the NAS.

I installed fun_plug, which went great. I made a directory (mkdir /mnt/HD_a2/lnx_bin) to hold my 2 kernel files, usb-storage.ko and ntfs.ko. No problems. I also created my directory which would point to my mounted drive: mkdir /mnt/HD_a2/lnx_bin/usb_test. I verified through the finder (I'm on a Mac) that this directory was created, which it was. I telneted (is that the word?) in and ran the 2 following commands:

insmod /mnt/HD_a2/lnx_bin/usb-storage.ko

insmod /mnt/HD_a2/lnx_bin/ntfs.ko

That went fine. This is where I run into troubles. I try mounting the disk using various commands:

mount /dev/sdc1 /mnt/HD_a2/lnx_bin/usb_test
The response to this is: mount: mounting /dev/sdc1 on /mnt/HD_a2/lnx_bin/usb_test failed: Invalid argument

mount -t ext -o umask=0 /dev/sdc1 /mnt/HD_a2/lnx_bin/usb_test
The response to this is: mount: mounting /dev/sdc1 on /mnt/HD_a2/lnx_bin/usb_test failed: No such device

When I run dmesg this is what I get:

Code:

Am I missing something? I promise you I've searched everywhere but can't figure anything out. Please help me.

Nevermind. I ran the command: fdisk -l and saw that the partition that I should be mounting was sdc2 and not sdc1.

stevelucky · 2010-09-14 19:34:58

Now I'm running into another problem. I can mount the drive and see it in my usb_test directory, but i'm unable to copy files every time I try it tells me:

The operation can’t be completed because an unexpected error occurred (error code -1303).

I suspect it's a permissions issue, although that doesn't quite make sense to me. I only need to be able to read from the USB drive, right? I should only be able to have to write to the NAS drive, which I can. Any thoughts?

karlrado · 2010-09-15 20:01:15

If you can write to the NAS drive without involving the USB drive, it is unlikely to be a permissions problem with the NAS drive.

Is that "The operation..." message coming from the Mac or a telnet shell?

Can you read the USB files from a telnet session on the DNS? If so, then the problem is with how the USB drive is exported to the Mac, and not the way it is mounted.

If you are interested in copying the USB disk contents to the NAS, I would telnet in and use Linux commands to copy the USB disk contents to /mnt/HD_a2. Don't do it from the Mac, even if you get the Mac to read the USB drive. You avoid the network overhead and any problems you might be having on the Mac. If the only reason why you wanted the USB drive mounted was to transfer the data, then you are done.

If you cannot read the files from a DNS telnet session, it is easy to try this: Try mounting the USB disk in /mnt, and not in /mnt/HD_a2. You might mkdir /mnt/usb_test; chmod 777 /mnt/usb_test. Unmount the USB drive from its current location and remount it the same way to /mnt/usb_test. I think that the way you are doing it should work, but not mounting it on top of an existing disk may help somehow. Note that you'd have to recreate this mount point each time you reboot. And you probably would have to go into the DNS config menu and export the /mnt/usb_test drive as a share, like the way /mnt/HD_a2 is exported.

Might try specifying the filesystem type explicitly in the mount command, and specifying a debug option if it is available for the type. I think it is for ext2 and your USB drive is probably either ext2 or ext3. The debug option may print some info that might help.

Sorry if this is not much help. I've never hooked up a USB drive to the DNS. But no one else was saying much.

I appreciate your help. I decided to change things up a bit. I was running a RAID 1 array, but have since decided to run 2 drives as standard disks and run a backup script to copy changes from drive A to drive B, nightly. Redundancy is nice, but I think I prefer the security, plus it offers the same redundancy with a 1 day delay.

That being said, I've now installed my new drive along side one of the old drives and am running the copy command via telnet: cp -r /mnt/HD_b2/* /mnt/HD_a2

This seems to be working well. It still feels pretty slow but then again, I'm moving almost 1TB of data, so what can you expect?

karlrado · 2010-09-15 20:35:43

That will take awhile, but is necessary.

I think your setup is better than using RAID 1, unless AVAILABILITY is super important to you. I use my disks the same way as you do. If I lose my "A" disk, it is easy for me to grab stuff off the backup on "B" until I can replace "A" and restore it. I don't need the level of availability that RAID 1 provides. There are also plenty of horror stories about RAID on the DNS-323.

So after your old disk is copied to the new disk and before you make your first copy of the new "A" disk to the new "B" disk, consider looking at "time machine" posts in this forum. I use rsnapshot, which is essentially the same thing. But it sounds like you've already got a backup script in mind.

scaramanga · 2010-09-15 20:38:18

You can do better with rsync: http://dns323.kood.org/howto:backup

stevelucky · 2010-09-15 20:46:09

@scaramanga: Yeah, I'd looked at rsync and figured that that was the way to go. It looks super easy to setup. I'd read about it here (http://dns323.kood.org/forum/t1150-Tuto … night.html) which seems to be a little easier to follow.

I have seen people with what seems like zero computer experience turning on RAID 1 in the D-Link forum, just because they think they are protecting themselves, and in reality on the DNS-323 they are adding to their troubles.

Personally I wrote my own cp -l/rsync backup script (I'm programmer), and put in things tailored just for me. It is a great way to backup. Once you understand that you are first creating links to yesterday's data, and then use rsync to replace links with the changed data it all is pretty easy to see how it works.

Yeah, but to be honest, I set my 323 up as a RAID 1 the day I got it about 2 years ago (knowing nothing at the time about RAID) and it's been great. I've had no issues whatsoever. Only now that I'm trying to upgrade my drives have I ran into some hiccups. That being said, I'm excited to be leaving RAID 1 for this new setup as it seems to offer a lot more choices and flexibility.

I wasn't saying that RAID 1 ensures you will have trouble (RAID 0 does double your risk), and it might even save you. But at best I think the odds of it causing you problems or saving you are about the same. On the other hand for 2 years you were paying two times the cost in drives and power, when that second drive could have been used for better uses like you are starting to use now. :-)

Great point. And I'm learning a whole lot more now by learning how to set this up and run automatic backups.

An often overlooked (and possibly undervalued) advantage of a RAID1 setup is,

...at the event of a disk failure, you have access to ALL of your data.

You can make a complete backup of ALL your data, just before you attempt the recovery procedure of the failed disk.

With all other disk configurations on the DNS-323, to recover your data from a failed disk event, you must rely on a periodic
scheduled backup; which could result in data loss, depending on how frequent your backup schedule runs and how frequent
your data changes. You are taking a risk that the data which is created between the time of the last scheduled backup,
and the time of the disk failure, is going to be lost.

Now, I'm not advocating that you run a RAID1 without some type of periodic scheduled backup, because your data is still
at risk from other disaster scenarios. But, IMHO relying on periodic scheduled backup without RAID1 leaves your data
vulnerable in a failed disk event, as described above.

For me, running RAID1, is a real good use for the second drive in the DNS-323. I can always put the periodic
scheduled backups on a USB drive or another network accessible drive. (in my case, I use my previous, single disk
NAS [linkstation], which the DNS-323 replaced, to store my scheduled periodic backups).
