Got my first unraid server up and running.  Works great when reading data off of it.  However, when I try and transfer many files to it (more than 20 or so movie files, ~1.5 GB each), I'll get an error on my windows machine "Network location no longer available", and I can no longer find the Unraid disks on My Network Places. 

 

I have to reboot the Unraid server before I can see the disks again.

 

Any thoughts?

 

thanks

A few questions that will probably help people more expert than me assist you..

 

When the "Network Location no longer available" message appears....

 

1/ What version of UnRaid are you using?

 

2/ Can you still access the UnRaid via the Web Interface to Stop & Reboot it?

 

3/ Do you have any other network attached devices that can be access after this message appears

 

4/ Can you "Ping" the UnRaid by name?  (Open a cmd prompt on your Windows PC and type "ping tower", assuming your UnRaid is called tower

 

5/ If the UnRaid doesn't respond with a ping respense time, can you "Ping" the tower by it's IP Address "ping 192.168.0.2", substituting IP address of your UnRaid is obviously.

 

6/ Is you IP address fixed or assigned by DHCP.

 

These could prove helpful in working out what's up.

 

Simple obvious things to try would be to try different Network cabling if you have any lying around.  Is you cabling Cat5e at least

 

Mark.

You could try using http://www.explorerxp.com/ for the transfer.  From what I remember from an old thread it is faster than explorer and could help you and your problem.

 

 

Thanks Mark - here's some answers:

 

1/ What version of UnRaid are you using?

 

Version 3.0

 

2/ Can you still access the UnRaid via the Web Interface to Stop & Reboot it?

 

No - the UnRaid server is not accessible

 

3/ Do you have any other network attached devices that can be access after this message appears

 

Yes, I have 2 other computers on the network and they are all accessible.

 

4/ Can you "Ping" the UnRaid by name?  (Open a cmd prompt on your Windows PC and type "ping tower", assuming your UnRaid is called tower

 

Haven't tried this, but I will try it if it crashes again.

 

5/ If the UnRaid doesn't respond with a ping respense time, can you "Ping" the tower by it's IP Address "ping 192.168.0.2", substituting IP address of your UnRaid is obviously.

 

Will try this too next time.

 

6/ Is you IP address fixed or assigned by DHCP.

 

Not completely sure what this means, but the IP address is assigned by my router, so I don't think it's a fixed IP address.

 

 

THANKS again

I'll give this a try too.  THANKS

I get this same problem.

 

limetech has said that my issue with writes going at 10MB/s then dropping to 0 then back to 10 (and on and on) is because the box can't sustain 10MB/s write speeds.. So the write buffer fills up and stops accepting new data until the buffer is empty.  If this process takes too long, your workstation will think the drive has timed out.

 

 

I'm hoping I either get a resolution from limetech or that 3.1 fixes my issues because with my current level of write performance I'm lucky to ever be able to copy a 1+ gb file to my unraid server.

 

 

Same story for me from time to time. It is not consistent and does not happen for each transfer.

It seemed to happen more when the data was being transferred to hard disks connected to the motherboard.

I have not had crashes when transferring to disks connected to the SATA cards.

You can try running the log window on your PC... everytime I did that to replicate the crashes... it would never crash!

Lol

if the problem is sustained write speed, you might want to grab a copy of RoboCopy from the Windows Resourse Kit. you can copy with many options including constraining the bitrate to a given level. if you 'slow' the copying down to the point at which your server can write, you might be able to get everything copied without error...it just might seem a little 'slower'.

 

FYI: Robocopy is included with Vista.

What motherboard?  If PCI disk controller(s), what ones?

Was there a solution to this problem?

I am experiencing the same problem, transfer 1 or 2 movies, all is well, immediately start a third, or sometimes the fourth, the system crashes, requires hard reboot and a parity check on restart. Hardware is Intel D915, have swapped out processor, power supplies, same problem.  Array has 4 drives, drive temps appears acceptable, between 37-41 deg C. Using 3.0 software.

I would upgrade to unraid 4.0 beta9...I had a similar problem in 3.0 and explorerxp worked for me as well as mapping the individual drives to my xp computer.  You could try that first but even though it's beta 4.0 is working great.

Thanks for the reply.

I was waiting for the final release of 4.0, but I'll go ahead and try try the beta.

Have  you tried different memory?  Although a system lockup can be software, it would have affected many of us with similar motherboards using the same drivers.  Your symptoms seem more like those of marginal hardware.  You did not mention swapping out the RAM, so I figured I'd ask about it?

 

Upgrading to 4.0beta9 would rule out the software, so it would not be a bad thing to try if you feel all hardware has been tested.

 

last time I had something similar happen on my LAN  it was the network card that was at fault. (Loss of network connectivity when trying to back-up one of my PCs to a different PC on my LAN using xcopy... years before unRaid) Have you tried a different network card?

 

Joe L.

Banshee, were you able to resolve this. If so would you please tell me how?

 

I'm experiencing the same issue with my 4.1 released server when I try to copy anything more than about a gig from a workstation to the server.

 

The IP stack fails and I loose the network connection on the server.

 

I'm running on an Asus P5LD2 R2.0 motherboard with built on Marvell 88E8053 PCI-E Gb NIC using 2x 1-Gig sticks of Kingston DDR2 800 RAM.

 

All other machines in the network switch continue to have connectivity so I tried connecting the server to different ports on the switch; no joy.

 

I have another NIC, my trusty little 3com 905B. But when I first tested unRAID on an older system, it didn't seem to have drivers for it. I'll try the 3com this evening in the new server to see if it behaves differently.

 

I also tried connecting my pair of HDs to the PCI chipset IDE port instead of the on-board ITE 8211F controller, but it didn't make any difference.

 

Any help is greatly appreciated.

Are you possibly writing to a User Share?  It is safe to write directly to the disks, but not to a User Share folder, as that feature is not supported yet. There are several other threads about this, and how it will start closing random threads down (such as networking).  We are awaiting unRAID v4.2, due next week hopefully, that should include security features and writable user shares.

 

If not, I don't know.

 

I'm witting straight to \\tower\disk1.

 

It's a new server and I only have 2 disks in it now. I'm moving data one disk at a time from the workstations into the server, then I will add the old disks, rinse and repeat.

 

Since all of the hardware is new, I'm going to go ahead and load XP on it tonight and run a network load test. See if it's a hardware problem or not.

It's fixed now, kind of.

 

The Marvell on board NIC works really well in Windows XP but not so much in unRAID 4.1. I went to Frys, dropped $10 on a bargain bin Trendnet 10/100/1000 NIC (Realtek chipset) and disabled the on board. It seems to be working better now.

So was there ever a definitive answer to this issue? 

 

My UnRaid 4.0 has been working flawlessly since I first set it up.  Suddenly today I've been getting the "specified network name no longer available" message when transferring big files.

 

I don't think the problem is "many files," but more "lots of data."  I'm getting the message when copying a 12gb single file.

 

Any solution yet? 

 

Thanks!
