Freenas Drops SMB Connection

[Shepppard]

I'm trying to transfer some large folders off of my Freenas over SMB. It keeps dropping the connection at various intervals and then I have to reboot the system and continue copying the files. I'm not sure if it is a RAM thing or not seeing as I have 8 GB. Here are my specs

Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz
Memory 8177MB
HDD = 2 x 2TB and 6 x 3TB all in 1 RAIDz

Also being such an extreme n00b at this I can't seem to figure out how to find the system error logs.

Any help would be great

Figured out the Log file and this is what I got.

This is a snapshot of my Volume Status



Any help on how to identify the disks would be great.

Seems that you have some bad disks. Try running zpool status -v from a terminal/console, should show your pool status and at disks io issues.

 

[Shepppard]

Oddly enough I ripped out every drive and identified the ones giving the IO errors and repluged everything back in and no issues. Have 810 GB transfered off of it without a dropped connection or error of any kind. Thinking it might be one of the SATA cables.

I have the same problem.
When I have some time, i will post my logfile.
Did you try to copy the files with FTP? Are you sure the problem is only SMB?

My configuration:
2x4GB DDR3, 1600Mhz
Asrock 880GM-LE
AMD II X2 255
Samsung Spinpoint F2 EcoGreen 1.5 TB, 5400 Rpm, 32 MB (in raid mirror, ZFS)

Hi,

I bought 2 new disks (WD red for NAS) and all my problems are solved.
Now finally my NAS works like a charme.
