Subject: [Cluster-devel] [GFS2 PATCH] Reduce truncate IO traffic
Date: Mon, 20 Aug 2007 09:29:53 -0400 [thread overview]
Message-ID: <46C99751.6030205@redhat.com> (raw)
Current GFS2 setattr call unconditionally invokes do_shrink even the
requested size and actual file size are equal. This has generated large
amount of extra IOs found during NFS benchmark runs. This patch moves
the relevant logic out of shrink code path. Since setattr is a system
call, the time stamps update is still required.
