If you are concerned about your Mac starting to run slow or become unstable, you may have looked into regularly running maintenance routines to clear caches, log files, and other temporary items from your system.You may have even seen advertisements for programs that automate these tasks.While periodic maintenance of your Mac is usually not necessary to keep it running in top shape, one exception is periodically checking your hard drive for errors.
You can look this up by running the command "diskutil list" to show the available devices and their respective device IDs.
For the second command, VOLUME is some name that will target the boot partition itself, instead of the drive. The first is to use the name of the boot volume, which should be surrounded by quotes if there are spaces in it (or you can properly escape the space characters with a backslash before them).
To use the fsck command, you can run it with the following flags to perform the repair: sudo fsck_hfs -fy /dev/disk0s2 Keep in mind that when booted to the OS X installation or recovery drive, the "disk0" ID will likely now represent the recovery drive instead of the system's main boot drive.
Therefore, be sure to run "disktuil list" again before running the command to find out the proper ID to use.
This makes sure that cache is populated with users who are very popular and are often queried for.
Also, we have intentionally added a log statement in the API call.We will make use of Spring Initializr tool for quickly setting up the project.We will use 3 dependencies as shown below: Download the project and unzip it. Spring Boot Application; import org.springframework.cache.annotation. Enable Caching; @Spring Boot Application @Enable Caching public class Application implements Command Line Runner package com.journaldev.rediscachedemo; import org.jpa.repository.The final option is to use the "fsck" routine, which is similar to the diskutil command and runs the same checking routines, but is a little barer.Apple recommends using diskutil whenever possible, but sometimes diskutil may show an error it cannot overcome, in which case fsck may be successful.However, even if the system seems paused for a long time, the routine should resume sooner or later.If for some reason the routine seems stuck (which is rare but may happen), since it is just a checking routine, you can force-quit Disk Utility to halt the check and return your system to a usable state.Unfortunately, formatting errors can happen even if you've just been using your computer in a normal way, so even though your system may be running fine at the moment, it can only benefit from a regular drive check.One way to do this is to simply reboot your system into Safe mode periodically, which among some other built-in maintenance tasks will run the "fsck" command-line tool to check the hard drive for errors and repair them if found.The third option is to simply target the root of the boot filesystem using a single forward-slash character.The following are examples of all three of these options: diskutil verify Volume "Macintosh HD" diskutil verify Volume Macintosh\ HD diskutil verify Volume disk0s2 diskutil verify Volume / When you run these commands, the system will check the boot drive and output status similarly to what is seen in the Disk Utility log window.
