Hi,
I have a DNS-320L with 1TB and 2 TB drives installed, running independently. As of today, I can no longer copy large files - .e.g a 1.2GB video file over to my NAS using CIFS to the second volune. The file appears to copy - using Explorer in Windows 10 and then gives an error "There is a problem accessing D:\Neil\Music\Movies" - the path where I am copying to. The path is accessible if I browse to it. The file appears in the folder but obviously cannot be opened as it is corrupted during transfer - it plays fine from the hard drive on my PC. The share has oplocks turned off and is only using CIFS. The same behavior happens if I access the NAS either via IP addresss - i.e. \\192.168.1.2\Data or by NetBIOS name - i.e. \\StorageServer\Data.
Copying a 100MB WAV file to the second volume worked fine - if a little slow. I was able to open it and play it from the NAS.
Copying a 1.7GB video file from second volume on the NAS to my PC works fine as well as copying a 3GB ISO from the first volume in the NAS.
Copying a 1.7GB file to the first volume on the NAS also works fine.
The problem seems to occur with writes to the second volume - reads are fine. I've scanned both disks and they came back fine.
The only error in the logs that seems relevant is:
CIFS: [192.168.1.103] closed the connection to service [Data]. - this happens on each large file copy attempt.
I'm seeing nothing in the logs relating to disk write errors. On Saturday, I copied over 12GB across with no issues - this seemed to start tonight.
I'm using a static IP for the NAS and have one user account set up on it. One share per disk and running firmware 1.07 - upgraded from the shipping version of 1.06.
Any help is much appreciated - three hours later and I'm still no closer to solving this, which is frustrating, as I work with servers for a living!
