Hi StephenB,

Thanks for your answer.

You are right. Not a Duo :)

Here are the active services : SMB, AFP, FTP, ReadyDLNA, UPnP, HTTP, HTTPS, SSH. No antivirus, no apps (I deleted the only apps we had). Hope it helps.

We have the Nas since more than 3 years and that is the first time we have these problems. Before changing model, every technical advice sounds good to me.

Regards.

Do you have quotas enabled on the volume? If you do, try disabling them (this is done by clicking on the volume settings wheel).

Unfortunately, no quotas enabled.

  If you're running 6.4.0, the quotas ARE enabled on the volume (quota accounting) even though you haven't set any quotas on any share.
  There is no GUI option in 6.4.0 to disable the quota accounting at the volume level.
  You really should update your firmware, 6.4.0 wasn't the best for ARM units. And a RN102 is not designed for professional use.
  There is a good chance your volume is heavily fragmented and the NAS struggling. If you want to use a RN102 and still get acceptable performance, you need to use the correct configuration, no bit rot protection, no compression, no quota accounting, as little snapshotting as possible, etc.
  If you start defrag and balance on your RN102 running 6.4.0, if the volume is in poor health, it will most likely collapse.

    Hi jak0lantash,
    
    Thank you for you answer.
    
    Is there any ssh command to check quota service status ?
    Updating the firmware is an option that i was (and am) taking seriously. It is always good to have such confirmation from experts.
    FYI, last weekend, degrag ended good. Balance took 2 days for (only) 80%.
    As you said, we lost performance...
    New nas is on the road.
    
    Regards.
