Subject: invalidate/drop filesystem caches & io buffers
Date: Wed, 8 Nov 2006 14:53:34 +0200 [thread overview]
Message-ID: <f36b08ee0611080453p5401de04td2fef8bff4d0efb3@mail.gmail.com> (raw)
I'd like to invalidate/free the filesystem caches and io buffer cache
How can I do this when I can't unmount the filesystem (and w/o reboot) ?
(I run filesystem I/O test that needs to start from fresh cache &
buffer state -- as emty as possible, like right after mount/boot).
I tried 'mount -o remount' but it didn't make any difference
on the timing. Apparently 'mount -o remount' did not invalidate
cases/buffers ? ( The difference between fresh run vs non-fresh
run timing is x5 times ).
Thanks
Yakov
