lvm，磁盘配额

 

1、 添加4快硬盘/dev/sdb /dev/sdc /dev/sdd /dev/sdc

2、 将4块硬盘分区

Fdisk –l /dev/sdb

N

P

Fdisk –l /dev/sdc

Fdisk –l /dev/sde

partprobe

3、 建立raid10

Mdadm –creat –auto=yes /dev/md10 –level=10 --raid-devices=4 /dev/sdb /dev/sdc /dev/sdd /dev/sdc

4、 建立物理卷pvcreate /dev/md10

5、 建立卷组vgcreate –s 16m vfastvg /dev/md10

6、 建立逻辑卷lvcreate –l 300 –n vfastlv vfastvg

7、 格式化逻辑卷 mkfs.ext3 /dev/vfastvg/vfastlv

8、 挂载逻辑卷umount /dev/cdrom

Mount /dev/vfastvg/vfastlv /mnt/

Mount –o  remount,usrquote,grpquota /mnt

9建立配额文件

quotacheck -avug

开启配额

quotaon -avug

创建用户

 #！/bin/bash

 groupadd laoyu

for username in laoyu1 laoyu2 laoyu3 laoyu4

do

useradd -g laoyu $username

echo "123456"| passwd --stdin $username

done

编辑配额

edquota -u laoyu1

 

filename                   blocks       soft       hard     inodes     soft     hard
  /dev/mapper/vfastvg-vfastlv          0          200000         300000          0        0 

 

calhost raid10]# edquota -p laoyu1  -u laoyu2
[root@localhost raid10]# edquota -p laoyu1  -u laoyu3
[root@localhost raid10]# edquota -p laoyu1  -u laoyu4

[root@localhost raid10]# edquota -u laoyu2 查看一下
[root@localhost raid10]# edquota -g laoyu
Disk quotas for group laoyu (gid 501):
  Filesystem                   blocks       soft       hard     inodes     soft     hard
  /dev/mapper/vfastvg-vfastlv                                                                       
[root@localhost raid10]# edquota -t  宽限时间
Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
  Filesystem             Block grace period     Inode grace period
/dev/mapper/vfastvg-vfastlv                  14days                  7days
~                                            

软连接
[root@localhost ~]# ln -s /home /mnt/raid10/
[root@localhost ~]# cd /mnt/raid10/
[root@localhost raid10]# ls
aquota.group  aquota.user  home  lost+found
[root@localhost raid10]# ll
总计 32
-rw------- 1 root root  7168 01-04 18:50 aquota.group
-rw------- 1 root root  7168 01-04 18:51 aquota.user
lrwxrwxrwx 1 root root     5 01-04 18:52 home -> /home
drwx------ 2 root root 16384 01-04 17:31 lost+found

 

给普通用户加个写的权限
[root@localhost ~]#chmod  o+w /mnt/

[root@localhost ~]#su - laoyu1

[laoyu1@localhost raid5]$cd /mnt/raid10

[laoyu1@localhost raid5]$dd if=/dev/zero  of=laoyu1 bs=1M count=270
md1: warning, user block quota exceeded.
