High HDD and CPU use in idle

[BET4]

Hi everyone. I'm using FreeNAS-8.0.4-RELEASE-p2-x64 (11367).

Some day my wife pulled out flash with freenas so it doesn't work. I reinstalled OS on another flash and run autoimport option for restore access for the data. There's 10TB of stuff.

After that for 22 hours my hdd are 100% in use especially ada4 anda ada5. Is it normal?

Is it normal? How long on this volume of information is the process of autoimport?

 

[BET4]

Maybe I have to post some other info for clarify situation?

Also it's a problem because of 100% use affect temp of HDD it's between 40 and 43. In normal state it's 35 celsius

Situation changes from time to time. E.g. now I get this.

But 5 mins after I get once again 100% busy

 

[BET4]

Guys, no ideas?

 

[cyberjock]

I'm sorry, but as I'm somewhat of a noob to BSD myself I don't know what commands will lead to what process is using the disk. I assume if you do a "zpool status" a scrub is not in progress?

 

[BET4]

Nope :(

Code:

[root@freenas] ~# zpool status
  pool: NAS
 state: ONLINE
 scrub: none requested
config:

        NAME          STATE     READ WRITE CKSUM

            gpt/ada5  ONLINE       0     0     0

errors: No known data errors

 

[cyberjock]

Unfortunately, I'm out of ideas. I have lots of things I'd want to do like get a breakdown of what is reading and writing, but I don't know how to do that in FreeNAS.

 

[BET4]

Meanwhile we I noticed changes some hours ago.

HDD in idle is 0% busy, so it's OK.

But system load and CPU usage still have some activity (but it isn't my activity).



Here's my top. But there's nothing special:

Pffff. Without any reason my NAS is going crazy after 2 weeks of wirking OK. System load and hdd load are 100%. Top is showing just 0.10% use of CPU.
