Readynas 526 hds acting strange

[dunkens]

For the past 3 days , there been some strange things going on , there is one partion using raid 5 over 3 hds .

There is a constant reading/writing every 3 seconds on those drives 24/7

Tried a reboot , still the same

Even tried to turn remove the network cable , still the same issues thougth it was a device that was reading/writing to the nas , but ..

Downloaded the log from the nas if someone could take a look and find something useful in there ?

What are the things you did before it happens? Try rebooting it.

Hi

Nothing really , same config months back

Tried to reboot , it behaves the same way after reboot

Its wierd .......

What apps are installed?  Do you have antivirus or file search enabled?  

Perhaps download the log zip file, and see if there is a lot of logging activity.

Hello

Plex is installed as app only

Did check the logs ,but cant find anything wrong .

But the strange thing, it keeps read/write every second to the drives

Even when nothing is connected to the nas .

Ive started a defrag on the volume , then balance and ill do another defrag .

Sure is wierd .....

Of course the logging itself writes to the NAS drives.  So check the larger ones to gauge the frequency of the logging.

Hi again 

But i dont understand the writing to the disk all the time 

It writes/reads to the data partion using raid 5 with 3 hds .

All the time , 24/7 every second 

This cant be right ?

Perhaps that anyone can check the logs ? and can find something useful that i didnt 

[dunkens]

This is how it looks , its the data partion that is behaving strange

[StephenB]

If you turn off plex does the pattern change?

[dunkens]

Hi

Nope still the same dosent have any paths pointing from plex to that data drive at all

I thought you said Plex was installed???  If so, the application and it's database are both on the data volume.

FWIW, my own RN526x is showing 1-8 write operations every minute at the moment over the past hour. Although disk spindown still seems to be working.

Hi I was meaning that no Movies etc is stored in the Data volume its on Another disk in the nas . But perhaps Plex is installed on Data volume , and its database . U said your nas was Reading , but in my case the nase is doing this 24/7 it never stops Reading/Writing on that data volume , no spindown at all Perhaps i should try to remove plex and see if it stop. ?

[StephenB]

You don't need to remove it, it's sufficient to turn it off.

[dunkens]

Hi

Did remove all data on those drives and and removed the setup , put it up again

and it seems to be working just fine according to the picture 🙂

Of course we didn't figure out the cause, but it's great that the problem is now resolved.
