A Linux administrator needs to expand a volume group using a new disk. Which of the following options presents the correct sequence of commands to accomplish the task?
D. fdisk, partprobe, pvcreate, vgextend
Explanation:
fdisk is used to create a partition on the new disk.
partprobe is used to inform the OS of the new partition and update the kernel's partition table.
pvcreate is used to create a physical volume on the new partition.
vgextend is used to extend the volume group to include the new physical volume.
The other options are not correct for the following reasons:
Option A is not correct because it is missing the pvcreate and vgextend commands, which are required to create a physical volume and extend the volume group to include the new physical volume.
Option B is not correct because it uses lvcreate instead of pvcreate to create a new logical volume, which is not necessary for expanding a volume group using a new disk.
Option C is not correct because it uses mkfs to create a file system, which is not necessary for expanding a volume group using a new disk. Additionally, it is missing the pvcreate and vgextend commands, which are required to create a physical volume and extend the volume group to include the new physical volume.
