Question
A server administrator is using remote access to update a server. The administrator notices numerous error messages when using YUM to update the applications on a server. Which of the following should the administrator check FIRST?
- A. Network connectivity on the server
- B. LVM status on the server
- C. Disk space in the /var directory Correct
- D. YUM dependencies
Explanation
YUM downloads repository metadata and packages into its cache under /var (/var/cache/yum or /var/cache/dnf) and records its database and logs there too, so a full /var file system produces many errors during an update and is the quickest thing to rule out. Network connectivity is clearly working because the administrator is connected remotely. Dependency problems produce specific resolution messages for particular packages rather than many errors across the update, and LVM status is unrelated unless storage itself is failing.
