[Solved] Extremely Slow Write Read Fine

Post by ctrlhomer »

Sorry if this has been posted else where I could not find it.

For almost 2 years I was using FreeNas 8. It was working fine. But for the past month or so I started experiencing extremely slow write transfers. The transfer speed ranged from 500kb/s to 1.25mb/s. Takes over 20 minutes to send a 1GB file. So I decided to change over to NAS4Free to see if it would clear up. Same issues. I am able to transfer the files from windows to windows just fine. Read transfers are fine.

I ran a iperf test results where 485/856 which is fine for me. So I know my network setup is fine.
I have checked for errors on my drives no issues that are being reported.

My zfs v28 pool is 8tb with ~2tb used (was still having the same issues before upgrading to v28)

I am completely lost for this one. To make matters worse I have had this issue completely go away for a few hours then start right back up.

Copying the file to another directory in my pool does the same thing. Same write transfers for both SMB/NFS shares.

I am running NAS4Free off a USB thumb drive, on a atom E-350 with 8gbs or ram.

Could the "disk power-on lifetime" errors be causing this issue?

My guess a drive is failing but is not reporting it. But I really dont have a clue where to look next. All computers on the network are affected the same way

Re: Extremely Slow Write Read Fine

check for the disk that have this line:

Code: Select all

5 Reallocated_Sector_Ct   0x0033   041   041   140    Pre-fail  Always   FAILING_NOW 1265
this indicate a fail disk, you need to replace to restore your old speed.

and read about WD green drives in NAS to correct parking head times to a better number for a NAS.
12.1.0.4 - Ingva (revision 7743) on SUPERMICRO X8SIL-F 8GB of ECC RAM, 11x3TB disk in 1 vdev = Vpool = 32TB Raw size , so 29TB usable size (I Have other NAS as Backup)

Thanks, exactly what it was. Never wanted to use the WD green drive in the first place but I had a spare laying around.

wait 2 years to correct head parking values of WD green drives is toooooo long, your other HD are in risk ( not necesary to change it, but you need to monitorize or see each month to be sure that still are in good conditions), use SMART to monitorize.

Hi,

Next hint, check the airflow in your system, 50 degrees centigrade are too much :o
Clean filters, check location from your NAS and put it to a cooler location, check blowers for function and dust, when you have had reduced the speed from the blowers increase it...
