From 6bd70aba5ab453459bb53b1e29f0e0650d6c311f Mon Sep 17 00:00:00 2001 From: David Teigland Date: Wed, 26 Apr 2006 15:56:35 -0400 Subject: [DLM] lock_dlm recover_status patch This saves the journal recovery result and makes it visible through sysfs. User space needs to know if the node actually recovered the journal or tried and gave up.
