I was abit confused where to put this problem, since its only relevant to OI and therefore I put it here.
For the past weeks I was building my own NAS based on OI 151 a7. Everything was sweet, until I bumped into one horrific issue which cause the link between my NAS to my PC dropped everytime I transfer large number of files over the link (~100 GBytes).
At the beginning of the file transfer, everything was fast ~110-120 Mbyte/s speed could be achieved easily. After 10 minutes, the link speed will drop to around 80 Mbyte/s and hovering around there, then another 10 minutes the speed will drop even lower to only 30-ish Mbyte/s and it will suddenly freeze the point-to-point link. From my OI NAS, I couldnt ping my client, however I could ping localhost, all zeros subnet and broadcast subnet just fine. While on my windows client, the link was shown as on for 10 seconds, and gone for 5 seconds and return and repeats.
To bring the link up again, I have to reboot my NAS and the similar symptoms happened over and over.
After I did some research why does this problem happen, I found some interesting info about some people having similar issues with intel 82574L NIC (e1000g).
One person suggested that he updated BIOS of his motherboard and fixed the problem
hardforum.com/showthread.php?t=1695908
while the other linux user had an update for their NIC's driver and also solved the problem.
I tried to search for the driver all over the place and couldnt find any and also I couldnt find any BIOS update for my motherboard.
On the other hand, I also have tried few attempts:
- Plugging and unplugging the cable
- Changing over 5 cables! produces same effect
- Changing to another onboard intel 82574L NIC (e1000g) on the motherboard
- Enable jumbo frame on both NAS and windows client.
- Decrease and increase the interrupt throttling rate.
- Direct memory access binding and changing the threshold size.
- Changing the MTU size from 1500 to 9216 (max value)
- Turning on/off flow control for Tx/Rx
- Forcing the NIC to be slave/master
- Turning off ACPI function for NIC
My PC and my NAS are set up in point-to-point links fashion.
NAS:
Openindiana 151 a7
ip: 192.168.2.1/30
Windows 7 client:
ip: 192.168.2.2/30
All the following commands were issued after the network came down, it is shown clearly by ipadm that the link is still 'up'!
All help will be appreciated, really desperate about this problem, it has been bugging me for days.
I assure you, there is a part number on there somewhere.
EDIT: This link shows some of the more obscure places the part number might be hidden. Perhaps it will give you a clue. Look towards the bottom of the page and it's illustrated.
