Subject: Print info if direct I/O is used
Date: Wed, 04 Jul 2012 16:44:17 +0200 [thread overview]
Message-ID: <4FF456C1.9070200@thomas-krenn.com> (raw)
Hi Jens,
it would be nice if an information is printed out if direct I/O has been
used:
Instead of
--------
/usr/local/bin/fio --rw=write --direct=1 --name=usb --filename=/dev/sdb1
usb: (g=0): rw=write, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1
--------
I suggest
--------
/usr/local/bin/fio --rw=write --direct=1 --name=usb --filename=/dev/sdb1
usb: (g=0): rw=write, bs=4K-4K/4K-4K, ioengine=sync, direct=1, iodepth=1
--------
So I can verify if the page cache has been used for a test when
inspecting the output files.
-Georg
