So, I just re-read the thread, and you can forget my last post. I
had thought the argument was that the data were not being written to
disk twice (assuming no separate device for the ZIL), but it was
just explaining to me that the data are not read from the ZIL to
disk, but rather from memory to disk. I need more coffee...
I think your confusing ARC write-back with ZIL and it isn't the sync
writes that are blocking IO it's the async writes that have been
cached and are now being flushed.
Just tell ARC to cache less IO for your hardware with the kernel
config Bob mentioned way back.
