[Cluster-devel] [PATCH] gfs2-utils: Added a new script called gfs2_lockcapture that will capture lockdump data.

The script gfs2_lockcapture will capture lockdump data(including dlm debug data) for the mounted GFS2 filesystems on a cluster node. In addition to the debug data, uname -a, hostname, date, mount, ps, etc are gathered. The script contains many configurable optons which include the number of iterati

[Cluster-devel] [GFS2 PATCH] GFS2: Eliminate redundant buffer_head manipulation in gfs2_unlink_inode

Hi, Since we now have a dirty_inode that takes care of manipulating the inode buffer and writing from the inode to the buffer, we can eliminate some unnecessary buffer manipulations in gfs2_unlink_inode that are now redundant. Regards, Bob Peterson Red Hat File Systems Signed-off-by: Bob Peters

[Cluster-devel] [GFS2 PATCH] GFS2: Use dirty_inode in gfs2_dir_add

Hi, This patch changes the gfs2_dir_add function so that it uses the dirty_inode function (via mark_inode_dirty) rather than manually updating the dinode. Regards, Bob Peterson Red Hat File Systems Signed-off-by: Bob Peterson --- diff --git a/fs/gfs2/dir.c b/fs/gfs2/dir.c index 259b088..9a356

[Cluster-devel] [GFS2 PATCH] GFS2: Don't skip rgrps for Orlov's sake if reservation is active

Hi, This patch changes function gfs2_inplace_reserve so that it does not perform the Orlov allocator resource group skipping in cases where we have an active reservation. Skipping an active rgrp is improper and gets our block reservation counts out of sync. Regards, Bob Peterson Red Hat File Sys

Re: [Cluster-devel] [GFS2 PATCH] GFS2: Don't skip rgrps for Orlov's sake if reservation is active

Hi, I don't think this makes sense... we will never have an active reservation when the orlov allocator is in use, since it is only ever used for new directory inodes, Steve. On Mon, 2012-11-12 at 13:31 -0500, Bob Peterson wrote: > Hi, > > This patch changes function gfs2_inplace_reserve so tha
