Last evening I took every bit of disk storage I had, and placed it on the Core server in the basement.
It was a mix/matched bunch of internal and external disks, and now they are all centrally located.
My reasoning for doing this was 2 fold. I was having issues with my Living Room MD, which uses the NVIDIA forcedeth driver for network, and I was getting a rash of CIFS and NFS timeout errors in dmesg and the logs. This was causing my core to eventually lock up, as the errors were consistantly getting more and more. This would then take down all my MD's as the core was hosed up, and angry.
The second reason I did this, is so that no matter what I do in the house now, I know my media will be available to all other MD's.
I have just ordered a new Motherboard and CPU for the living room:http://www.newegg.com/Product/Product.aspx?Item=N82E16813131324http://www.newegg.com/Product/Product.aspx?Item=N82E16819103211
Which are on a combo deal right now for $114.99 Free shipping.
This board uses a broadcom based on board 10/100/1000 NIC, and is reported to be supported well. My core has 2 Broadcom Gigabit NIC's currently. It also has HDMI, DVI, and Optical SPIDF out. More will follow after I try to install it, I will post it to the wiki. It does have ATI graphics, but we shall see if that causes an issue or not.
Back to the topic, If you are experiencing an excessive amount of CIFS, and Network related issues, and you have the opportunity, try to centrally locate your storage, or use NAS type, this resolved all my issues, even though I am replacing the system board and CPU. It made quite a difference in the amount of times it popped up the annoying (Added blah-blah drive blah-blah) and now when using the FaM menu in the web admin, Media Files Sync just flies. It is much faster than it was, when the storage, internal and external was connected to the MD with the bad NIC.
Anyways, just my 2 cents. I hope if anyone is experiencing this issue, give it a try, centralize everything. After all that was the original intent of the core anyways.
