I think it was caused by using a DD bs of 4M.
I put it back to 128k now and there doesn't seem to be an issue anymore.
The Linux Kernel is generally terrible in the area of IO queues.
I was meaning to ask something else though.
When my DD copy to the share completes, it often ends with an error:
"closing output file 'XXX': Input/output error"
From a bug on NFS it appears to be related to short I/O timeouts.
Is there anything I can do to mitigate that?
I don't want DD to close with an error.
I am using completely general mount options.
There is apparently sometimes an IO timeout when it closes the file.
