From 49eb776ed9d92a91d3b1a24d83755e051bce96ff Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 27 Feb 2019 13:32:36 -0700 Subject: [PATCH] gfs2: log which portion of the journal is replayed When a journal is replayed, gfs2 logs a message similar to: jid=X: Replaying journal... This patch adds the tail and block number so that the range of the replayed block is also printed. These values will match the values shown if the journal is dumped with gfs2_edit -p journalX. The resulting output looks something like this: jid=1: Replaying journal...0x28b7 to 0x2beb This will allow us to better debug file system corruption problems.
