cluster/stripe: implement the coalesce stripe file format

2012-07-16T04:39:39+00:00

The coalesce file format for cluster/stripe condenses the striped
files to a contiguous layout. The elimination of holes in striped
files eliminates space wasted via local filesystem preallocation
heuristics and significantly improves read performance.

Coalesce mode is implemented with a new 'coalesce' xlator option,
which is user-configurable and disabled by default. The format of
newly created files is marked with a new 'stripe-coalesce' xattr.
Cluster/stripe handles/preserves the format of files regardless
of the current mode of operation (i.e., a volume can
simultaneously consist of coalesced and non-coalesced files).
Files without the stripe-coalesce attribute are assumed to have
the traditional format to provide backward compatibility.

extras/stripe-merge: support traditional and coalesce stripe formats

Update the stripe-merge recovery tool to handle the traditional
and coalesced file formats. The format of the file is detected
automatically (and verified) via the stripe-coalesce attributes.

libglusterfs/fd: while dumping the fd_ctx use fd->xl_count

2012-05-18T13:02:23+00:00

While dumping the fd_ctx when statedump is issued fd->xl_count should be
used to determine the number of xlators instead of using latest graph's count,
since while creating the fd only those many slots would have been allocated
as the number of xlators in the graph at that instant. Then the graph would have
changed, thus the xl count.

All the above things should happen before any operation is done on fd, otherwise
fd_ctx_set will allocate the extra slots for the new xlators present in the
graph.

Also added the program which can be used to reproduce the bug.

Updated the Ubuntu upstart jobs for glusterd in extras/Ubuntu.

2012-03-18T07:34:57+00:00

Using upstart jobs, instead of an initscript, solves Bug 765014.
See also: https://bugs.launchpad.net/ubuntu/+source/glusterfs/+bug/876648

The new upstart jobs split the work of starting glusterd & mounting glusterfs volumes into two parts: a glusterd service runner and a glusterfs volume moung blocker which waits for the service runner.

This is the method preferred by Ubuntu developers to block a mounting event until a required service is available.  These changes will be included in the Ubuntu glusterfs-server package starting with release 12.04, Precise Pangolin.

Tested on Ubuntu 12.04
