+# Bash script by Gene Alexander (http://www.eracc.com/contact)
+# of ERA Computers & Consulting (www.eracc.com, blog.eracc.com, shopping.eracc.com)
+# Written using vim, the BEST plain text file editor in all of Creation.
+#
+# Teach yourself bash scripting: http://tldp.org/LDP/abs/html/index.html
+#
+# Purpose: To check fragmentation on XFS with xfs_db and run xfs_fsr on XFS mount points that
+# are above a specific fragmentation threshold.
+#
+# What is xfs_db? Use 'man xfs_db' to find out.
+# What is xfs_fsr? Use 'man xfs_fsr' to find out.
+#
+# Any busy files, such as open logs on /var/log, will be skipped. To defragment logs one should
+# wrap this script with another script to stop and restart logging. Or, even better, write
+# one's own script just for defragmentation of the logs.
+#
+# Warranty: NONE. Use at your own discretion and be aware that data loss is on your head if
+# you choose to use this script.
