This article will guide you on the different #command line options to extend #disk space storage in #Linux thereby allowing you to add #storage capacity to your #VM. If your filesystem has the resize capability, that capability is what you use. 1. Check if disk is available: #dmesg | grep sdb. 2. Check if disk is mounted: df -h | grep sdb. 3. Ensure there are no other partitions on disk: fdisk -l /dev/sdb. 4. Verify the #disk: fsck /dev/sdb. 5. Resize the #filesystem: resize2fs /dev/sdb.
