Hello,

 

I have a weird issue with my new unraid install that i did not experience on my test install with different hardware.

 

First i though it was a network issue but it is not, the box never stops responding to ping, only SMB locks up and is unaccessible randomly when writing files to the array.

 

How do i go about to diagnose the issue? Tried finding a SMB log file but i couldn't find it, usually it is in /var/log/samba but the files appear emtpy?

Go to Settings -> SMB -> SMB Extras and add:

 

log level = 3
logging = syslog

Then check syslog, note that Samba will get very chatty so it can fill it up after a few hours.

thanks! array must be stopped doing some pre clears will have to report back with findings tomorrow.

So i've been doing a lot of testing and transferring over 40tb of data using SMB.

Logging brought some clues to whats going on, but i do not think the problem is related to SMB, it's probably an unraid thing?

 

So this only occurs at the end of a file/begginning of a new transfer. SMB logging throws randomly "access denied" to the file, it's like the unraid system sometimes are having the files "in use" as soon as it has completed a transfer, while most of the time it doesn't.

 

I throttle the speed to which the transfer is going then the problem does not occur, so probably a mixture of things resulting in a file being randomly locked and smb throws access denied. 

 

I am doing all my transfers directly to the array with the default disk settings, i did try the "speed improvement" plugin but i couldn't see it yealding any better performance, i am averaging 60mb/s writing directly to the array after the inital memory cache is out.

 

Once i am done transfering my data to the unraid system i can start telling if this smb lock will occur when streaming data too.. It most likely wont, also i will enable my cache drives once the data is moved so new data will end up on those initially and hopefully that will work properly.

 

If you have ideas feel free to comment!
