    Is it possible to extend the space on a disk without adding another disk and no downtime?

    • @Michael,

      Yes, it’s possible to extend the size without adding new disks, but we should have enough space in VG.

      To extend the space for any logical volumes we don’t require any downtime, only we need downtime in the case of reducing disk space by unmounting.

      Thanks & Regards,

        I know that you need space on VG. But what if I don’t have and I add space to the disk from vSphere or whatever virtualization product? Then it involves downtime to increase the disk space, right?

    Great article. Can’t do this with built in GUI tools so this article was dead on for what to do.

    • @Mark,

      In real world production environment, only DB servers are installed with GUI more over LVM GUI will not be configured.
      It’s good to practice in CLI to keep hands on any platform.

      Thanks & Regards,
