why do drives spin when not accessed?

Hi,
I have a 323 with 2 drives (raid 1), connected to a router/hub, with two windows based laptops in the house on the network. I'm trying to figure out why every 30 minutes or so my 323 drives start spinning and acting as if I'm accessing them, even though I'm doing nothing that would appear to need them to be activivated (e.g. while working on a document stored on my laptop, or just browsing the web. I opened up task manager but can't tell if any of the processes are the ones causing this.
Any ideas?

Re: why do drives spin when not accessed?

My DNS-323 is on a shelf behind me so when it spins up I can hear it, and it will remain in standby for hours on end - so I would guess that you have an application that is accessing yours.

Try disconnecting the network cable for an hour and see what happens - if it stays in standby, you know what ever causes it to spin up is doing it through the network connection.

Re: why do drives spin when not accessed?

Thanks. I disconnected the network cable but this apparently was not the cause. The drives still start up spinning very often and work away for a good 15 minutes before powering down and then starting again after not too long.

Re: why do drives spin when not accessed?

Have you installed fun_plug on your DNS-323?

Re: why do drives spin when not accessed?

What firmware and how did you set-up your drives (Raid1 etc.)?

Re: why do drives spin when not accessed?

Another thing I should mention, is that I don't think it's always been doing this - I seem to remember last week spending hours at the computer without it ever starting up, but there has been no change in the recently that would have explain why it started doing this in recent days.

@i2Paq - The drive are Raid 1 (though after reading some other threads I'm thinking of changing to standard and having one copy to the other, and a third kept off-site for back-up)

@fordem - I haven't installed the fun_plug - I'm not much of an expert and am a simple windows user (one day I hope to make the change...), and so have been hesitant about doing anything other than setting up the 323 from the box and leaving as is. Would the fun_plug stop this problem of the constantly spinning drives?

Re: why do drives spin when not accessed?

The reason I asked about fun_plug is that once you have it installed, it allows you to run all sorts of stuff that can cause problems like you describe - the other known reason for the drives spinning back up is a print job stuck in the print queue, have you been using the print server?

Re: why do drives spin when not accessed?

I am also noticing this too. Once in a while, it would spin up after being asleep. Not running any media servers or print server. What else could be causing this? Running 1.04 and no other hacks.

Re: why do drives spin when not accessed?

Just assigned all suers to a group and got rid of the default ALL permissions. Drives are still sinning up once in a while. The last time this happened, I launched the iTunes client on a computer. Could this be accessing all the mapped drives and causing the 323 to spin up?

The itunes server is rescanning the disk at a certain interval.

Re: why do drives spin when not accessed?

iTunes server is not enabled. I had mentioned that I opened the iTunes client. I tried syncing time to my local machine instead of over the internet. Let's see if this resolves the issue.

Re: why do drives spin when not accessed?

I am also having the same issue. No fun_plug, no connection to the dns (ftp, smb, etc..), but itunes server is running.

Any ideas?

Re: why do drives spin when not accessed?

I changed time sync'ing to Computer from Internet. Try that, it seems to have solved the issue for me. I will have to work with the unit more as today, I was not near the NAS long enough but at the moment, this seems to have worked. Wish me luck!

Re: why do drives spin when not accessed?

Simple troubleshooting of the mysterious drive spinning issue:

The drives spin up if something bothers them. It can be either
1. Internal program running on the dns-323
2. External query coming from the LAN

To rule out 2. disconnect the unit from the LAN. If that is the case, connect the unit back and start disconnecting individual network nodes to find the one that is nudging the unit. Most likely it will be a permanently mounted share.

DNS-323 disks with default settings and the iTunes server off never spin up unnecesserily. Did you make any changes to the default settings? Reverse them and check the issue again.

Re: why do drives spin when not accessed?

ok, the entire morning after the backups ran, drives did not spin up again. I think in my case, it was due to the time sync'ing from the internet. I chose "from my computer" and this seems to have fixed the problem so far. note, in my ase, no fun plug or any media servers have been enabled. hope this helps others out there with the same issue.

For what it's worth

1 - I use an ntp server on the internet to sync my time, without my drives spinning up
2 - Choosing "from my computer sets the time once.

Re: why do drives spin when not accessed?

Hello,

IMO the a lot of the 'unexplained' instances of one or more drives spinning comes about because of swap partition usage.  I know that in my RAID 1 configuration, one of the drives (only one) spins up, sometimes, when I connect to the device using telnet.  If it were accessing the data on disk (as different to swap partition), then both disks would spin.
