surely it should be backed up, if you intend to press the reset button or not?

maybe you could use RAID1 as a backup and take one of the disks out before pressing the reset button.

I did as suggested.. yanked one of the drives and hit reset. (Have to hold in for 10 secs apparently.)

That did the trick!

When brought up and configured, the drive contents were fine. I plugged the other drive in hotswap, and it still says Synced, so RAID-1 seems to have survived the reset.

Thanks guys!

yep, of course; RAID1 is for drive-backup, not data-backup.  But this is the first step.. getting offset or a second DNS-323 is down the road

Cheers,

RAID1 is intended to reduce the potential impact of downtime caused by drive failure.

RAID 1
Mirrored set (minimum 2 disks) without parity. Provides fault tolerance from disk errors and single disk failure. Increased read performance occurs when using a multi-threaded operating system that supports split seeks, very small performance reduction when writing. Array continues to operate so long as at least one drive is functioning.

Thank you - now perhaps you would care to give us a definition of fault tolerance.

OK - the DNS323 will NOT automatically rebuild the array if an empty drive is hotswapped in.

Scenario - 2x250GB Seagate Barracuda 7200.9 disks in a RAID1 array occupying the entire disk.

Test methodology - data - about 2GB - was copied to the disk, the right side drive was pulled, as expected the data remained accessible, a clean (ie no partitions) Seagate Barracuda 7200.9 disk was added in the empty bay, and after the LEDs stopped flashing the data was still accessible - BUT - when the left side drive was pulled, the data was no longer available, as would have been expected had a rebuild occurred - in fact the unit appears to be hung as I cannot access it either from the web admin interface or Windows Explorer.

Edit - the unit is so thoroughly hung that it would not power off from the front panel, I had to unplug it - and on reconnecting the "replacement" drive to my Windows box, the disk management tool shows it as still having no partitions.

As I pointed out in my previous post - the ability to hot plug the drives is not the issue, this is supported by SATA - for the unit to be considered hot swap, it needs to recognise when a new drive is hot inserted and automatically rebuild the array - as would be the case for example with a Dell PowerEdge, an HP ProLiant or an IBM xSeries server that supports hot swap drives.

No, but since your the one repeating yourself feel free. I thought the discription was better than "RAID1 is NOT a form of backup". Now at least they can start to see the logic.

Hi Jeff, where is the reset pin?  I can't find it in the manual either.  I've removed the drives but the only button I see is the on/off.

I've dug around but can't seem to find anything on how to do a hardware reset.

Does anyone know if this will also reset the machine to the original firmware?

Thank you
Mark

Mark,

The reset pinhole is located on the back of the unit between the DC-IN(Power) and LAN(Ethernet) port. Resetting the unit will return the CONFIG file to default however it will not revert to a previous firmware because when upgrading the new firware is written to flash.

And as a heads up a note has been added for where the reset pinhole is to the next upcoming documentation release. Sorry for the inconvienence.

Ah-ha!  That would be the one labelled RESET!  Cool, thanks.  I realise that I need to hold it in for about 10/15 secs but any other "Correct usage" instructions would be useful (power off first or not, LAN/USB cables in or out, how do we know its worked - does the unit flash its LEDs, etc)

Its nice to see you on here, Dlink.  We're all anxiously looking forward to firmware update 1.04, any idea of how close it is to release?

Thanks
Mark

@Dlink

can you advise as to what 1.04 (official release) will comprise of? eg, enhancements / fixes / got rid of?

also, on the beta forum's, someone mentioned that torrents will be implimented. will that be in 1.04 or later? .. just curious

cheers

are the NAS boxes you mentioned taylored for home users like the 323 is and within similar costs?

i like my 323 thus far (even with the bugs it has) .. but naturally, id rather stick to what i got rather than purchasing something new to do the same thing
