Subject: [PATCH 3/9] xfs_mdrestore: correctly account bytes read
Date: Tue, 22 Dec 2015 08:37:03 +1100 [thread overview]
Message-ID: <1450733829-9319-4-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1450733829-9319-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Progess indication comes in the form of a "X MB read" output. This
doesn't match up with the actual number of bytes read from the
metadump file because it only accounts header blocks in the file,
not actual metadata blocks that are restored, Hence the number
reported is usually much lower than the size of the metadump file,
hence it's impossible to use to guage progress of the restore.
While there, fix the progress output so that it overwrites the
previous progress output line correctly.
