1. login to vpshere and expand disk to new space for the vm
2. echo the following command – change controller to match ; you can also reboot to see the changes
echo "- - -" > /sys/class/scsi_host/host0/scan
3. login to VM – determine if filesystem mount is directly written to; if so you can expand the filesystem directly
Disk /dev/sdc: 107.4 GB, 107374182400 bytes, 209715200 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
4. check fstab to see which identifier your partition is mounted by
UUID=a3ea5cce-cd61-4f40-9a53-36364c8a0a6c / ext4 defaults 1 1
5. use lsblk command to check the device (determine partioned or unpartioned) ;in the case below sdc (unpartioned)
lsblk –fs /dev/disk/by-uuid/a3ea5cce-cd61-4f40-9a53-36364c8a0a6c
NAME FSTYPE LABEL UUID MOUNTPOINT sdc ext4 root a3ea5cce-cd61-4f40-9a53-36364c8a0a6c /
6. from the above we can resize the filesystem (on-line) directly even if it is root partition
resize2fs /dev/disk/by-uuid/a3ea5cce-cd61-4f40-9a53-36364c8a0a6c
7. if XFS fileystem
xfs_growfs /mnt/yourFS
