linux mint - nas

pappa_golf

since moving from windows to linux mint , my nas drive keeps being accessed , about every 10-20 mins or so ,

the computer (nuc) is left on 24/7 , and merrily goes to sleep , but the nas keeps the cat awake at night

due to her bad temperament , and sharp claws (the cat not the wife!) I would like to turn this useless to me facility off.

nas is a dlink dns320l , no changes have been made to it , it seems to go into sleep mode (as set) then gets woken up by the PC


any ideas ?

I could be indexing the files when the system is quiet.

Is it actually the drive making the noise or the small cooling fan in the unit starting up?

The fan in my dns320L is annoyingly loud...

What are the drive temps?
my 2 drives idle around 28c-30c
35c when spinning
and 38-42 when running accessing data for extended periods

If it's the fan then you have 3 options :

1) Swap the small fan for another quieter one (it's possible but they have the red/black wires reversed so you'll have to re-wire the new fan) or try and squeeze a few bits of foam/rubber between the fan and the unit to reduce noise.

2) Remove the black enclosure, (This drops the average drive temps by a few c and stops the unit's temperature sensor from reading hight temps, which stops the fan kicking in to high mode) only down side is the metal rack holding the drives is not secures to the mainboard inside, so you can knock the drives loose easily! but a few long M3 screws and nuts can fix this. ALSO you can try just keeping the top lid off, that helps drop the average temp a few c but the fan will still kick in from time to time.

3) Change the temperatures levels for the fan. The ranges which control the fans "off/low/high" settings can be changed if you have root access to the unit. They are held in a simple text file which can be changed if you have root access.

To access the root you'll need to install OpenSSH on the unit from here : http://dlink.vtverdohleb.org.ua/Add-On/?.

if it's not the fans.

What are you using the Linux Mint box for? Media center or just general PC stuff?

Is the NAS just backups or are you using it for file/media storage?

my Linux box only accesses the NAS when needed I've set up remote drives in /etc/fstab between shared NAS folders and my Home directory.

I'm storing my Media on the NAS but my linux box is running Plex server instead of the NAS (it's faster and quieter!)

Think using the "remote" drive option stops my Ubuntu box from constantly checking if the remote folder is still accessible. It only looks for the remote folder if I go into the mapped folder (i have to wait a few seconds for the drives to spin up and access the folder data).

I have the disk set to go to sleep after 10 mins of inactivity.

OK , its NOT the fans , the flippin ligts all turn on !

the nas holds a mixture of media (vid/audio) and files

no plex installed on the PC or nas

problem solved... ^__~ lol

The NAS wakes the cat but the PC doesnt?

Why is the Computer on 24/7? Since getting the 340L which is very similar to your 320 but with 4 bays i have been able to switch my PC off at night.

If you need a download doing the NAS will do it for you without a PC needing to be left on.

the pc is an intel nuc that uses less tham %ugger all to run , it is on a vesa mount behind the monitor , , walk into room move mouse and it wakes up .

it uses a m.2 card , so no moving parts ,

the machine does NOT download overnight

there must be a simple setting that is telling linux to check that network drives are still there

what/where is this setting so that it can be disabled ?

How are you accessing the files on the NAS?

Are you using a shared folder? (i.e. use the networking section of the file manager to browse over to the NAS folders and select files.)

Are you using mounted folders?
(Folders look like they are in your home directory but are actually on the NAS.)

Do you keep programs running or file browsers open when you put the NUC to sleep? (both can cause it to check the NAS periodically.)

pappa_golf

ok , in linux mint , the networked drives (nas) show under network ,

I have

PC-xxx
dlink (lower case) Unknown (application/octet-stream)
dlink (upper case) Unknown (application/octet-stream)
windows network


note: dlink shows twice ,

multimedia services is OFF on nas

S0litaire

OK
The only default service I've got running is "NFS Service" all others are stopped.

You could give this a go (I think It's a safer/cleaner way to mount remote folders onto a Linux machine at boot, so it should stop it accessing the NAS unless it needs to):

The path to the shares on the D-link should be something like

/mnt/HD/HD_a2/<your folders>

So in the fstab file it should read something like :

192.168.1.###:/mnt/HD/HD_a2/   /mnt/NAS     nfs   users.rw.auto 0 0
