This weekend I did a triple upgrade...

 

2 new drives

upgrade to pro

upgrade to 4.2.1 (from 4.0.10b)

 

Now when streaming HDTV from one of the new 1TB SATA drives, I get pauses as the program (MythTV) waits to fill it's buffer.

 

Has anyone else seen this?

 

It worked fine from the 500 gig drives when I was at 4.0.10b.

 

Is there a way to "downgrade" back to an older version to test without having to rebuild the array?

 

 

Has parity completed?

 

I think all it takes to downgrade is to shut down the array, swap files back to the old ones (if you have them), and reboot.

I recently tried 4.2.1 and I was getting severe stuttering (pausing), which might be similar to what you are experiencing.

 

I did not want to mess around with anything so I reverted back to 4.0 and playback was normal after that. I concluded that there must have been a driver problem, but I did not investigate further as I plan on replacing the motherboard with the one shipping with the prebuilt systems.

Hi,

 

I'm having a similar issue when upgrading from 4.0 to 4.2.1.  It takes for ever to connect to it using windows to one of the shares. Even to the flash share. Took 5 minutes to copy a 1.5meg file to it.

 

Reverted back to 4.0 and everything is back up to speed.

 

Seems that SMB on this version is a little sick possibly. As when I telnet onto it or use the Web front end, it doesn't seem to be slow.

Ya parity finished in a few hours as did the format/setup of the new drives (expanded the array at the same time).  We actually watched during this process and didn't have any issues (although it slowed down from 50+k/s to ~35k/s).

I'm glad I'm not alone.  I think I'm gonna roll back after everything finished recording tonight and see if it makes a difference.

Not seeing the same issues, performance is as good as ever on an Asus P5something or other board and on the original Intel board. Are you seeing anything when you tail the logs?

I got nothing in the syslog.  No time to play with it further today.  Maybe tomorrow.  Hard to post on my n800.

l'm a new user of unRAID and had the same problem, playing back anything (though a user share, didn't try a drive share) would stutter unbearably - reverting to 4.0 also worked for me.

 

Hardware is MSI P965 Platinum.  Don't have a parity drive running yet.

I've done some more testing - the problem occurs with 4.1 and 4.2

 

I would be happy to stick with 4.0 for now, but both my Promise TX2 controller and JMICRON controller don't have drivers in 4.0 - which leaves me unable to use any of my PATA drives... 

I suspect the issue involves the ethernet chip.  You may want to try a different one.  You can pick up a 10/100 card for $10 or so.

I just came here to post that I'd fixed it by replacing the network card with an Intel Pro 100.

 

Thanks :-)

 

The network chipset I had a problem with is: Realtek RTL8111B PCI Express Gigabit Ethernet controller

Realtek is broken in 4.1 and 4.2.  Stay at 4.0 until 4.3 is out.
