Good Morning:

 

I am an avid unraid user (4.5.6) and recommended it to a friend of mine. Yesterday we put together a machine with a msi 870-g45 mobo, 4gb or ram, 3 seagate lp 2tb drives, amd athlon x2 black and using a sandisk cruzer blade 4gb flashdrive and a plus registration. After having to clear the cmos from the mb to be able to boot the computer, unraid booted (4.7). I assigned the 2 data drives and no parity initially to copy some media from my unraid to my buddy's. I noticed is was a slow transfer rate but continued until the middle of the batch, then it stopped copying. I canceled the copy and proceeded to see if I could read the data off i just transferred to the new unraid server. I could see the data, however if I tried to play a video it will not stream, ifconfig showed no data loss/collisions. I spent the rest of the afternoon/evening reinstalling unraid to the flash drive, changing user share permissions, tried another flash drive, assigned only 1 drive, until I decided to give version 5 a try. Using the same components I booted with beta 4, configured eveything, and applied the new permissions under upgrade utilities. The server is working 100%, copied stuff over and was able to read it without a hitch.  Questions I have: Any additional compatibility with Motherboards present in 5.0? Is the MB incompatible with 4.7? Could there have been a problems with permissions in the 4.7 setup? Anything else I should check? How "safe" would it be to run beta 4 as his main server considering 4.7 is giving us trouble? Should I try my version 4.5.6 since its working 100% ?

 

Appreciate if anyone has answers and/or comments,

If my quick search brought back the correct motherboard that you are using, this one, then your problem is most likely the Atheros LAN chipset (the NIC card) that is built into that board.  Atheros NIC's have a tendency to not work very well at all with unRAID (do a search in the forum about it).

 

You can either:

a. Disable the onboard NIC in BIOS and add a Intel based PCI NIC card

or

b. Buy a new motherboard

 

the 5.0 series is based on a new Linux Kernel that may work better with the NIC card on your board, hence the reason it worked.

 

NOW, with that said, 5.0b4 has a tendency to lose the disk assignments.  There were a lot of changes in the Linux Kernel and changes in unRAID (for AFP stuff and more) that required a rework of the way HDD are detected.  The first attempt in changing that did not quite work correctly.  5.0b5 is supposed to have a newer way of recognizing disks that will be more bulletproof.

 

My suggestion is to NOT use 5.0b4 for right now.
