According to libtool three individual numbers stand for
CURRENT:REVISION:AGE, or C:R:A for short. The libtool
script typically tacks these three numbers onto the end
of the name of the .so file it creates. The formula for
calculating the file numbers on Linux and Solaris is
/path/to/library/<library_name>.(C - A).(A).(R)
As you release new versions of your library, you will
update the library's C:R:A. Although the rules for changing
these version numbers can quickly become confusing, a few
simple tips should help keep you on track. The libtool
documentation goes into greater depth.
In essence, every time you make a change to the library and
release it, the C:R:A should change. A new library should start
with 0:0:0. Each time you change the public interface
(i.e., your installed header files), you should increment the
CURRENT number. This is called your interface number. The main
use of this interface number is to tag successive revisions
of your API.
The AGE number is how many consecutive versions of the API the
current implementation supports. Thus if the CURRENT library
API is the sixth published version of the interface and it is
also binary compatible with the fourth and fifth versions
(i.e., the last two), the C:R:A might be 6:0:2. When you break
binary compatibility, you need to set AGE to 0 and of course
increment CURRENT.
The REVISION marks a change in the source code of the library
that doesn't affect the interface-for example, a minor bug fix.
Anytime you increment CURRENT, you should set REVISION back to 0.

This patch is an attempt to provide some much needed
cleanup for future maintenance of `mount.glusterfs`
- Add checks for command failures
- Spliting large code into subsequent simpler functions
- Standardized variables
- use 'bash' instead of 'sh' - since string manipulation
and variable handling is far superior
- Overall code cleanup and Copyright change to Red, Hat Inc.
- Add new style of mounting with a comma separated list
~~~
$ mount -t glusterfs <IP1/HOSTNAME1>,<IP2/HOSTNAME2>,..<IPN/HOSTNAMEN>:/<VOLUME> <MNT>
~~~
- Update age old `manpage` with new options :-)

at syslog side, log message is identified by its properties like
programname, pid, etc. brick/mount processes need to be identified
uniquely as they are different process of gluterfsd/glusterfs. At
rsyslog side, log separated by programname/app-name with pid works but
bit hard to identify them in long run which process is for what
brick/mount.
This patch fixes by setting identity string at openlog() which sets
programname/app-name as similar to old style log file prefixed by
gluster, glusterd, glusterfs or glusterfsd

Problem: NFS allows exporting subdirectories but there is not support for
providing AUTH on per directory basis.
Fix: Modified nfs.export-dir to include AUTH parameters
e.g. nfs.export-dir "/dir1(10.1.1.2),/dir2(10.1.1.0/24|host1)
During mount operation NFS will check if the IP from where the connection is made
is configured in the AUTH parameter, else the mount operation will fail with
EACCES error.
Updated admin-guide and volume set help message.

Goal of this health-checker is to detect fatal issues of the underlying
storage that is used for exporting a brick. The current implementation
requires the filesystem to detect the storage error, after which it will
notify the parent xlators and exit the glusterfsd (brick) process to
prevent further troubles.
The interval the health-check runs can be configured per volume with the
storage.health-check-interval option. The default interval is 30
seconds.
It is not trivial to write an automated test-case with the current
prove-framework. These are the manual steps that can be done to verify
the functionality:
- setup a Logical Volume (/dev/bz970960/xfs) and format is as XFS for
brick usage
- create a volume with the one brick
# gluster volume create failing_xfs glufs1:/bricks/failing_xfs/data
# gluster volume start failing_xfs
- mount the volume and verify the functionality
- make the storage fail (use device-mapper, or pull disks)
# dmsetup table
..
bz970960-xfs: 0 196608 linear 7:0 2048
# echo 0 196608 error > dmsetup-error-target
# dmsetup load bz970960-xfs dmsetup-error-target
# dmsetup resume bz970960-xfs
# dmsetup table
