[Cluster-devel] [PATCH 00/56] fsck.gfs2: Support for checking gfs1 file systems


I previously posted a series of 44 patches to fsck.gfs2 that
fix numerous bugs and allow fsck.gfs2 to operate on GFS1 file
systems.  Since I posted those patches, I received feedback
and changed the patches accordingly.  I've also done extensive
testing and discovered and fixed several more bugs.
There are now 56 patches in all.  As Andy Price suggested,
I renamed their descriptions to make them shorter so
they're not cut off.

My latest version has passed all my tests and I'm ready to
start pushing them to the upstream gfs2-utils git repository.
But before I do, I wanted to post the corrected patches and
the new ones here.  I'm not reposting the patches that got
ACKed.  Here is the complete list of patches:

In addition, I just put my experimental new fsck.gfs2,
which contains all these patches, on my people page at this


It is experimental, so make backups and try it AT YOUR OWN RISK.
However, it is also better tested than all of its predecessors.
