ZFS and large files thru CIFS

[akmodi]

Hi,

I have imported a 3x3tb RaidZ pool. This is running on a dual opteron board with 12 GB Ram.

All is well when I try and copy small files from the NAS to win 7, but when I try and copy large files (more than 300 MB) , I get the error: There is a problem accessing the share.

Memory usage 52% , pool scrubs without error.

This had driven me round the bend. Can you help?

more info is needed. please post some logs, and jpg of your SMB config
Do you enable tunning of some kernel variables? .

Post your SMB settings ( I'm interesting to see if you use SMB2 and AIO that have some compatibility isues).

I had the same problem today and resolved it by disabling Enable Asynchronous I/O (AIO). I'm using SMB2. Everything has been fine since then.

ddimick is right!

disable AIO when using smb2 Protocol...!
