Spin-down guard disabled

[batondebois]

I've looked around in the forum and the help, but cannot figure-out why the spin-down guard for the internal hard-drives is disabled. When I grep:

Code: Select all

root@homenas:/ # ps -ef | grep noflushd
root      2943     1  0 11:28 ?        00:00:00 noflushd -n 5 /dev/sdb
root      2989  2138  0 11:32 pts/0    00:00:00 grep noflushd


I see that it is enabled, but in the web I see that it is in fact disabled:

Code: Select all

Current setting:   disabled, Inactivity period 0 Minutes


Is this a compatibility error with my disk? Could there be a media deamon taking over (I've looked around and they all seem disabled. The disks don't sound like they spin down.

Seems disk spin down is not active on sda (system disk) but enabled on sdb, the second disk.
Normally noflushd should list as well sda as sdb. In your case it only list sdb.
The reason must be that sda is incompatible with commands used by nofushd to check disk settings and activity. As result the web interface mentioned disabled.
You could try to start noflushd for sda by giving this command at command line

Code: Select all

noflushd -n 5 /dev/sda

And see what response you get

What you said rang a bell, and I remembered that I installed the firmware on sdb. I wiped everything and transferred data on sda, and no everything works as planned. Do you think that this was this the problem? Now I see enabled on the web interface.

Hi

Indeed this may explain this issue.

First, on a 2big2, the command line should be in all case

Code: Select all

noflushd -n xx /dev/sda /dev/sdb

. The firmware reads the nas database to get the disks list having to be monitored by noflush daemon. So that would mean the nas database is corrupted.

Please to post these outputs

Code: Select all

grep '<vol>' -A 20 /etc/nas_conf_db.xml
grep '<disk>' -A 20 /etc/nas_conf_db.xml
grep '<hdparams>' -A 7 /etc/nas_conf_db.xml

In my NAS I only have a drive in the A port at the moment. Here is the output:

According with your outputs, all is right :scratch
But it seems you tried to change the inactivity period because currently the value is 15 min whereas in your first post it was 5 min

Code: Select all

root      2943     1  0 11:28 ?        00:00:00 noflushd -n 5 /dev/sdb

So can you reboot the nas and check the running noflushd commandline

Code: Select all

 ps -ef | grep noflushd

Note: Did you edit manually the nas database ? because these lines are wrong and never the firmware can do that

Code: Select all

   <rsyncd>
      <enable>false</enable>
      <modules>
         <enable>false</enable>              <------------------ this is a wrong line
      </modules>
   </rsyncd>

by enabling again rsyncd and enable a module all should be right again
