New Unraid build. Less than 1MB/s read over network, full speed write to array


Recommended Posts

I have a new unraid build with version 5.0b6a and the following specs:

Processor:          AMD Phenom II X4

Motherboard:      Biostar A780LG3

Ram:                 Kingston 2 GB DDR3 1066

Power Supply:     Corsair CX500

HDDs:                2x 2 TB Seagate LP(1 parity, 1 data)

                       1x 2 TB Samsung F4 (data)

                       1x 1 TB Hitachi Deskstar (cache)

 

I have flashed the latest firmware for both the Samsung and Seagate HDDs.  I did 2 preclears per drive.  Everything started just fine.  I assigned my drives and created my shares without an issue.

I had no problem transferring files to the array at 90-100MB/s(prior to parity).  With parity, I can still write to the cache at 80 MB/s or directly the array at 30+MB/s.  My problem is with transferring from the Unraid server to my Windows machine.  I can transfer from other places in my network just fine. I'm getting less than 1 MB/s from the Unraid server.

 

I have attached the syslog, results of ethtool eth0 and the disk performance test from unmenu.

Result of disk speed test:

 

/dev/sda:

Timing cached reads:   3186 MB in  2.00 seconds = 1593.32 MB/sec

Timing buffered disk reads:  338 MB in  3.01 seconds = 112.35 MB/sec

 

/dev/sdb:

Timing cached reads:   3182 MB in  2.00 seconds = 1590.70 MB/sec

Timing buffered disk reads:  402 MB in  3.01 seconds = 133.55 MB/sec

 

/dev/sdc:

Timing cached reads:   3122 MB in  2.00 seconds = 1560.35 MB/sec

Timing buffered disk reads:  340 MB in  3.00 seconds = 113.18 MB/sec

 

/dev/sdd:

Timing cached reads:   3096 MB in  2.00 seconds = 1548.24 MB/sec
