linux中磁盘容量配额

001、查看一下当前系统

[root@PC1 home]# hostnamectl
Static hostname: PC1
Icon name: computer
Chassis: n/a
Machine ID: 8f7f58c7ef6f42489c3251e9f474be72
Boot ID: e43741739e584fb4930cf608e15aed74
Virtualization: vmware
Operating System: Red Hat Enterprise Linux Server 7.0 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.0:GA:server
Kernel: Linux 3.10.0-123.el7.x86_64
Architecture: x86_64

002、查看是否支持磁盘容量配额

[root@PC1 home]# mount | grep boot
/dev/sda1 on /boot type xfs (rw,relatime,seclabel,attr2,inode64,noquota) ## noquota， 说明不支持磁盘容量配额

003、修改配置文件

[root@PC1 home]# vim /etc/fstab ## 编辑配置文件
#
# /etc/fstab
# Created by anaconda on Tue Sep 13 14:28:43 2022
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/rhel-root / xfs defaults 1 1
UUID=70a81f5c-a185-4bf5-8bea-38a638645def /boot xfs defaults,uquota 1 2
/dev/mapper/rhel-swap swap swap defaults 0 0

004、重启系统

reboot

005、查看磁盘容量配额权限

[root@PC1 home]# mount | grep boot ## 检查磁盘容量配额
/dev/sda1 on /boot type xfs (rw,relatime,seclabel,attr2,inode64,usrquota) ## 已经包含磁盘容量配额
