Subject: [Ocfs2-devel] [PATCH 1/1] ocfs2/dlm: Increase o2dlm lockres hash size
Date: Wed, 5 May 2010 16:25:08 -0700 [thread overview]
Message-ID: <1273101908-20804-1-git-send-email-sunil.mushran@oracle.com> (raw)
Lockres hash size of 16KB is far too small for large filesystems (where we
have hundreds of thousands of lock resources stored in the table).
This patch increases it to 128KB.
