How to transfer disk space in linux system? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Actual combat under fedora24

Use the following command to view disk usage

Df-lh file system capacity used used mount point devtmpfs 3.9G 0 3.9G 0 0 / devtmpfs 3.9G 0 3.9G 0 0 / dev/shmtmpfs 3.9G 2.9m 3.9G 1% / runtmpfs 3.9G 03.9G 0 0% / sys/fs/cgroup/dev/mapper/fedora-root 60G 46G 12G 81% 3.9G 400K 3.9G 1% / tmp/dev/sda1 477M 141M 307M 32% / boottmpfs 787M 0787M 0% / run/user/0/dev/mapper/fedora-home 141G 60M 134G 1% / home

The mount directory corresponding to / dev/mapper/fedora-home is / home

The mount directory corresponding to / dev/mapper/fedora-root is /

From the above list, we can see that the fedora-home is very large, but the fedora-root is very small, so we practice moving 1G.

Unmount the / home directory

Umount-v / home

Check the disk to be transferred

E2fsck-ff / dev/mapper/fedora-home# all five steps of the operation result of this command must be passed.

The display results are as follows

E2fsck 1.42.13 (17-May-2015) step 1: check inode, block, and size step 2: check directory structure step 3: check directory connectivity Pass 4: Checking reference counts step 5: check cluster summary information / dev/mapper/fedora-home: 130190max 10838016 files (0.1% non-contiguous), 8077341 blocks 43338752

Change the disk size of / dev/mapper/fedora-home

Calculation method: 141g-transfer 1g = 140g

Resize2fs / dev/mapper/fedora-home 140G

Cut disk space

Lvreduce-L-1G / dev/mapper/fedora-home

Remount / home

Mount-v / home

Transfer to / root

Lvextend-Little 1G / dev/mapper/fedora-root

Make the / root space effective

Resize2fs / dev/mapper/fedora-root

This is it, then execute the df-lh command
