Unable to copy large files from DNS-323

[Jeff Chieh]

Greetings,

After many years of happily running Alt-F on my DNS-323, I've finally decided to upgrade to a QNAP TS-251+.

However, I've having difficulty in copying over my data.

Current setup is two 3TB drives in a Raid 1 configuration.

Disks

Bay	Dev.	Model	Capacity	Power Status	Temp	Health
right	sda	ST3000DM001-1CH166	3.0TB	active or idle	39°C/102°F	passed
left	sdb	ST3000DM001-1CH166	3.0TB	active or idle	40°C/104°F	passed

RAID

Dev.	Capacity	Level	State	Status	Action	Done	ETA
md0	2794.0GB	raid1	clean	OK	idle

Mounted Filesystems

Dev.	Label	Capacity	Available	FS	Mode	Dirty	Automatic FSCK in
md0		2.7TB	1.2TB	ext4	RW		16 mounts or 178 days

The problem is this: when I try to copy over large files to, say, my computer via Windows 7, it starts copying but then eventually hangs and gives me a Network Error:

"There is a problem accessing \\DNS323\Folder1

Make sure you are connected tot he network and try again."

When this happens, I check the Alt-F status page and notice that the CPU is stuck at 100%, even after I cancel out the request to copy.


Sometimes it even crashes Windows Explorer with the following message:

Problem signature:

  Problem Event Name: InPageError

  Error Status Code: c000020c

  Faulting Media Type: 00000000

  OS Version: 6.1.7601.2.1.0.256.48

  Locale ID: 1033

  Additional Information 1: 5f6a

  Additional Information 2: 5f6a17eaebed3f111ff90ce5656d82f1

  Additional Information 3: 57a7

  Additional Information 4: 57a7b13f3e13081f111a5333e4828259

Another thing to note is that copying TO the DNS-323 is fine. It's only copying FROM the DNS-323 that it seems to crap out.

Does anyone have any ideas how to debug this issue? Or any alternatives to get around it, for example not using Windows to copy files? Since I'm just moving my files over to a new NAS, I don't need a root cause, just a workaround.

For example, would there be a way to take one of the drives from the DNS-323 and plug it into my QNAP and use the QNAP to copy over the data? Or plug it into my desktop directly?

So good news is I was able to fix the "Network connection lost" issue by downgrading from RC5 to RC4.1

But still curious if people know of any quicker ways to copy the data

Have you applied the fix described in the "RC5 network data corruption" top-posted topic?
