Re: [CentOS 6.6] lvm 관련 명령어 - Disk Quota 설정

1. fdisk -l /dev/sdb 로 sdb1 (100 GB Full 사이즈 생성)

sda,sda1,sda2,
sdb,sdb1 (100 GB)

2. fstab 편집

$ more /etc/fstab

3. File System 체크

$ df
Filesystem           1K-blocks    Used Available Use% Mounted on
/dev/sda3             21340384 1363440 18886232   7% /
tmpfs                   960988       0    960988   0% /dev/shm
/dev/sda1               194241   57061    126940 32% /boot
/dev/mapper/datavg-home1_lv
                       999320    1284    945608   1% /home1

4. 빨강색 명령어 필수

$ setenforce 0 or /etc/selinux/config에서

#SELINUX=enforcing
SELINUX=disabled
같이 설정변경

$ quotacheck -cug /home1
$ quotacheck -cvug /home1

@쿼터 활성화는
$ quotaon -avug
/dev/mapper/datavg-home1_lv [/home1]: group quotas turned on
/dev/mapper/datavg-home1_lv [/home1]: user quotas turned on

@쿼터 비활성화는
$ quotaoff -avug 혹은 $ guotaoff /home1

$ ls -l /home1
total 32
-rw-------. 1 root root 6144 Jan 14 16:12 aquota.group
-rw-------. 1 root root 6144 Jan 14 16:12 aquota.user

5. 유저생성 & 쿼터설정

$ useradd jkkang -d /home1/staff/jkkang -g staff

$ edquota -g staff
Disk quotas for group staff (gid 500):
Filesystem                   blocks       soft       hard     inodes     soft     hard
/dev/mapper/datavg-home1_lv          0          512000          512000          0        0        0

500 MB 설정 = 5120K x 100 = 500 MB

$ quota -g staff

$ repquota -g staff

$ su - jkkang

$ pwd
/home1/staff/jkkang

$ dd if=/dev/zero of=file bs=1024k count=600
dm-0: write failed, group block limit reached.
