设置 Quota
- 确保使用的是xfs文件系统
- 在
/etc/fstab里给需要设置quota的磁盘加上uquota,pquota注意没有空格
# /home was on /dev/centos/home during curtin installation
/dev/disk/... /home xfs defaults,uquota,pquota 0 1
# /scratch was on /dev/centos/scratch during curtin installation
/dev/disk/... /scratch xfs defaults,uquota,pquota 0 1
加完后重新 mount (需要先检查 lsof /home 和切断nfs), 检查 mount 的结果里, 应该有 uquota,pquota 参数
- 设置 quota
-x = expert mode
-c = command
-u = user quota
-d = default
xfs_quota -x -c 'enable' /software
xfs_quota -x -c 'enable' /scratch
xfs_quota -x -c 'enable' /home
xfs_quota -x -c 'limit -u bsoft=4588g bhard=4588g -d' /software
xfs_quota -x -c 'limit -u bsoft=1024g bhard=1024g -d' /scratch
xfs_quota -x -c 'limit -u bsoft=100g bhard=150g -d' /home
设置后即完成, 登录各账号检查quota是否正确运行中.
- 查看 quota
-N = ignore headers
xfs_quota -c 'quota -Nu' /scratch | awk '/\/software/ {print $1, $2, $3}'
xfs_quota -c 'quota -hNu' /scratch
