Hi Rick, dentunusd shows how many unused directory entries (dentries) you have in the kernel's memory cache. Dentries are stored on disk, and contain information about a specific directory. They're cached in memory for faster access as you change directories. For a rough example, try 'mkidr /tmp/test; vi /tmp/test'.
Here's an article on managing this value. I'm sure there are many like it, but this is just one approach: http://rackerhacker.com/2008/12/03/reducing-inode-and-dentry-caches-to-keep-oom-killer-at-bay/ -Brad Rick Truett wrote:
Hello, I am looking for an explanation of the value returned in the dentunusd field from the sar -v command. I have values in teh millions and would like to understand why the value is so high. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
