RaidZ2 write performance < 10MB/s

[ZFS Noob]

Here's a stupid question: has one of the machines connected at 100 Mbit, rather than 1 Gbit?

 

[Joo Chung]

If the copy of audio files has completed... Why not test performance of the ZFS pool locally on the FreeNAS box? Make sure its not a problem with the performance of ZFS.

Ubuntu shows SMB:\ to the directory.

So I grab my files and drag them over to the appropriate destination folder.

SMB=Samba. This is a CIFS share.
I can reach "easily" 50 MB/s over CIFS with my crappy NIC. :p
Unfortunately, I don't have any more idea for you.

Right, but do you want me to:

1. Take CIFS share and remove the Ubuntu box's IP
2. Create NFS share for only the Ubuntu box's IP

Will that make a hill of beans?

Nah... checked both boxes

With a Realteck in the loop and performance issues the answer will be: consider upgrading your Ubuntu box with an Intel NIC. A very affordable solution.
Are you able to test on an other client?

 

[marcevan]

Can do but need to get a plug-in NIC. Just don't have one nor another box with one to test from.

Prior to me redoing the pool I noticed if I was upstairs, my Win7 with Realtek was dragging copying files from or to the NAS. That machine goes trough the ISP's router and that router has a hard line to basement switch. The NAS and Ubuntu are on the switch in the basement. Now traffic from/to the NAS from Ubuntu back then was blazing around 90 MB/s.

So only thing odd is that the freeNAS pool got killed and redone as RaidZ-2 on 6x 3-TB drives.

 

[Joo Chung]

Did you test the ZFS pool locally ? Best to confirm than to assume.

 

[marcevan]

I have not yet as I didn't want to run anything while the transfers were occuring.

But as far as zpool status and SMART, everything is tip-top.

Wonder if it's NTFS drive in the Ubuntu and it should have been ext4.
