Question

Adjust Logical Volume Size Adjust the size of the logical volume "vo" and its filesystem to 300 MiB, ensuring that the filesystem content remains unchanged. Note: Partition sizes rarely match the requested size exactly, so a range of 290 MiB to 310 MiB is acceptable. For ext4 filesystems, use resize2fs to take effect immediately; for xfs filesystems, use xfs_growfs to take effect immediately. Correct Answer: See the below explanation Explanation Explanation/Reference: Solution: # Scan logical volumes # Extend the logical volume. With -rL, the filesystem space is adjusted immediately after extending the volume. [root@node2 ~]# lvextend -rL 300M /dev/myvol/vo # Check the changes [root@node2 ~]# lsblk [root@node2 ~]# lvs # Verification [root@node2 ~]# df -h

Explanation

The lvextend command is used to resize a logical volume to a specific size, automatically resizing the underlying filesystem simultaneously.
