Blog Post – 2 Gluster related files

In the previous post we had installed gluster in debug mode. Lets have a quick look on the files that get installed with gluster.

Remember, when we do a make install, our prefix for destination for install is /usr/local. If you are installing from a repo then it will be /.

Libraries and Executable:

• Most of the libraries get installed either directly under “/usr/local/lib” or within “glusterfs” folder under that.
• Some of the libraries which are used internally in gluster get installed in libexec.
• The only two executables that are generated are “gluster” and “glusterfsd” placed in /usr/local/sbin.

Scripts:

• Helper script for mount “mount.glsuterfs” is in /sbin.

Documents:

• Vim syntax file for vol files, man pages and benchmarking tools are provided in /usr/local/share.

Header files:

• Header file for the gluster api is provided in /usr/local/include for others to include while building on top of the api.

Configuration files:

• Configuration files that get installed are in /usr/local/etc/glusterfs/.
• We have logrotate config file to hold parameters that logrotate uses to archive logs.
• Important file that you should notice here is the glusterd.vol.

Note:

• If you look into glusterd.vol file, you will find that working directory is /var/lib/glusterd. That is a directory we should be exploring.
• Also remember , all our logs go into /usr/local/var/log/glusterfs.

In the next post we will make use of this information to understand how gluster works.
