Start over - Force drives to be seen as new

Hello,

I'm been getting to know my dns-323 and now I would like to start over and try a new hard drive configuration.

The first time I turned on the unit I configured RAID-1 (two identical 750GB drives) and set the "Volume" to be the whole disk. Now, what I would like to do have two volumes rather than 1 large one (and keep RAID-1 if possible). How do I get the dns-323 to repartition and format the drives? I have made a backup of my files, so at this point it's ok to loose all the data on the drives.

In a way, I want to revert the dns-323 to the same state when I first took it out of the box. Will a hardware reset be enough or do I need to fiddle with the drives?

Thanks,

Alvin

Re: Start over - Force drives to be seen as new

You'll have to 'fiddle' with the drives - go into the RAID setup and change the configuration there.

Please be aware - you can choose to have a RAID volume that is less that the total capacity available, in which case whatever space remains will be used to create a second JBOD volume, however, if either of the disk holding the JBOD volume fails, you will lose access to all the data contained in the volume, regardless of which disk it was physically stored on - also - the JBOD volume will not be automatically recreated if/when a failed drive is replaced.

Think twice before using JBOD volumes on this device - in my opinion - the risk is not worth the benefit.

Re: Start over - Force drives to be seen as new

So, there is no way of not creating a JBOD volume. What I understand, and please correct me if I am wrong, is the with JBOD, the un-RAIDed partitions are joined together logically to appears as one partition?

Is it possible, through the dns-323's web configuration to create a two partitions: 1 RAIDED with another drive and the remaining portitions being formated as seperate Volumes? So, I would have something like this:

Volume_1 - RAIDED between 2 drives
Volume_2 - A partition on drive 1
Volume_3 - A partition on drive 2

Is that possible using the web configuration tool?

Re: Start over - Force drives to be seen as new

I'm going to play with the web configuration's format tool (under Tools->RAID).

Before I do, I would like to uninstall FFP first so that I can start as close to an out-of-the-box state as possible. According to this: http://dns323.kood.org/forum/viewtopic.php?id=4817

Seems like I just need to delete the following (using ffp telent?):

/mnt/HD_a2/ffp
/ffp    <--- symlink

Then I just reboot.

Now, I had set a root password and did call store-password.sh. Is that going to cause me any problems? Should I clear the root password first (e.g. usermod -p '' root)?

yes you will need to use ssh/telnet to delete /mnt/HD_a2/ffp (and subdirs) or change permissions for /mnt/HD_a2/ffp (files and subdirs) so you can delete via your OS otherwise you won't have permission to delete all dirs/files.  You also need to delete/rename fun_plug which starts ffp in the first place.

What about the root password? Do I need to clear it and then run store-passwords.sh? Or am I ok to leave it set?

Nevermind, I just left it and reformatted. I believe that when I reinstall FFP, ssh will use the same password has had originally.
