Storage Management

A critical application stores its configuration files and database in the JFS2 filesystem /app.

To avoid application downtime, which action would you take to create a point-in-time-consistent volume group backup by using savevg?

  • A Quiesce the application and unmount the file system /app then run savevg backup
  • B Reboot the system into single user mode and then run savevg backup when the OS starts
  • C Find application process id (ps -ef ...) and execute echo kill -6 /proc/pid and then run savevg
  • D Use the appropriate flag to create a snapshot and then backup the snapshot
Explanation

The savevg -T option creates external JFS2 snapshots for the volume group backup. These snapshots provide a stable point-in-time image without requiring the filesystem or application to be quiesced or unmounted.
