Editor to share with you the example analysis of Xfs file system related operations in CentOS7. I hope you will get something after reading this article. Let's discuss it together.

Xfs is the default file system type of CentOS7.0, and different file system types have different creation, check and adjustment commands, so you should pay attention to the distinction.

Resize the Xfs partition (only increase):

Lvextend-L 120g / dev/mapper/centos-root # increased to 120g

Lvextend-L + 20g / dev/mapper/centos-root # add 20g

Xfs_growfs / dev/mapper/centos-root # perform adjustments

Note: the adjustment command for ext2/ext3/ext4 is resize2fs, as follows:

Lvextend-L 120g / dev/mapper/centos-root # increased to 120g

Lvextend-L + 20g / dev/mapper/centos-root # add 20g

Lvreduce-L 50G / dev/mapper/centos-home # reduced to 50G

Lvreduce-L-8G / dev/mapper/centos-home # minus 8G

Resize2fs / dev/mapper/centos-root # perform adjustments

Repair command:

Xfs_repair / dev/sdb1

Note: the following are repair commands for Jfs, Ext2, and Ext3, respectively:

Fsck.jfs-y / dev/sdb1

Fsck.ext2-y / dev/sdb1

Fsck.ext3-y / dev/sdb1

Problems encountered in the adjustment:

1. When you use the mke2fs command on the Xfs file system to change to ext2, you need to modify the corresponding file system type in the file / etc/fstab

2. Different file system types have different creation, check and adjustment commands, so we should pay attention to the distinction.
