NFS Mounting Questions

[SpaceCoyote]

Hopefully this is the right forum.

I am having some trouble with stuttering with high bitrate content streamed from my ReadyNAS NVX which is gigabit connected and supports transfer speeds of around 100 MB/s. I suspect that the stuttering problem I have is with CIFS, so I am planning to go NFS.

I am planning on loading the 0.4.1.9-6 firmware, but am only interested in the NFS component. I have been reading around the NFS mounts and I have a couple of questions:

1. My ReadyNAS is current sharing a single folder called "Media" over CIFS and NFS with guest access. The Media folder contains two subfolders which I currently access from my WDTV Live using Network Shares. If I apply the correct xmount command, is that all I need to do? I'm sure I found something about having to specify a CIFS share, even if it isn't used, but I can't seem to find it again.

2. I have been reading about the unmount that may happen if I don't specific a username and password, is this correct and should I apply credentials to the shares? And is this for both CIFS and NFS?

Finally, if there is anything I should be on the lookout for, I would appreciate some tips.

Thanks in advance.

k, first off I imagine your nas is 100mb/s...

Next I think you should consult your owners manual for how to properly configure NFS and then read up on google exactly what NFS is and how you go about it.

NFS and Samba only connection is that both are protocols that allow exporting/mounting of remote filesystems. After that there is zero connection pretty much.

Once you have NFS running on your nas, then telnet in to the wdtvl and execute this to find out if you have permissions to mount the NFS.

Code: Select all

showmount -e your.nas.ip.address

if it says you have permission then mount it following instructions in net.mounts file. If it says you don't then go back to step one and figure out how to correctly configure your nas.

Thanks for the quick response.

My NAS is gigabit, and when I transfer to it from my PC, I get between 50 and 100 megabytes per second. It's kind of irrelevant, but I was just trying to explain that it will support transfer speeds well in excess of what the WDTV Live should need

I have created an NFS share on the NAS, but without anything to test it with, I'll have to wait and see when the WDTV is hacked.

I'll give it all a go tonight and hopefully it will all work first time.

ok, so 1000mb/s ... if you would've said 105MB/s I probably would've gotten it

I don't understand, wait until what is hacked how?

I will upgrade the firmware on my WDTV Live tonight to 0.4.1.9-6 and test the NFS. Then I'll let you know how I got on.

Thanks for the replies.

Right, I've installed the 0.4.1.9-6 firmware, tested the mount, which worked, so I've added the line

"xmount 192.168.0.16/Media Media nfs" into net.mounts in /conf which seems to auto mount the folder at start up.

If I browse to the folder via USB 1, it can see the folders and the files within, but if I try to play anything it displays the filesize correctly, then waits for 60 seconds or so, then shows resolution and bitrate information, but never plays.

Any thoughts please?

EDIT: - This is sorted - got the CIFS Interceptor going........Also, is there any way of accessing the NFS share without going via the USB icon? I read somewhere about some CIFS interceptor, but I can't find it again?

EDIT 2: Could this be an NFS streams issue? I can only configure my server's NFS share with upto 16 streams. Originally had it set at 8, setting it to 1 slowed everything down considerably, but increasing to 16 seems to have no effect.

Sounds to me like your nas might be one of the ones that, for whatever reason, works best with proto=tcp as a mount option.

also is there a reason you're using 0.4.1.9-6 and not 0.4.2.0?

[SpaceCoyote]

I did try Proto=TCP, but it made no difference to the playback issue.

Regarding the version, 0.4.1.9-6 seemed to be the current version when I downloaded it from the "WDLXTV-Live – The extreme upgrade" entry on b-rad.cc

To be honest, I had an absolute nightmare last night, I uploaded the firmware and spent time trying to get it going, decided that I'd go back to official firmware while I figured out the issue and somewhere along the way I lost about 1.7TB of media - I don't know where its gone, it's just gone! Spent the rest of the night running FSCK and parity checks - can't find anything - looks like the whole share has been deleted!
