修改fstab

~root@df:/data# vi /etc/fstab# /etc/fstab: static file system information.## Use 'blkid' to print the universally unique identifier for a# device; this may be used with UUID= as a more robust way to name devices# that works even if disks are added and removed. See fstab(5).## <file system> <mount point>   <type>  <options>       <dump>  <pass>proc            /proc           proc    nodev,noexec,nosuid 0       0/dev/mapper/ubuntu-root /               ext4    errors=remount-ro 0       1# /boot was on /dev/sda1 during installationUUID=1a891701-bfed-42e6-a41a-a8438099daae /boot           ext2    defaults        0       2/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0/dev/mapper/cryptswap1 none swap sw 0 0/dev/data/home               /data/home                ext4    defaults,usrquota,grpquota        0 0

备注

如果使用组配额是指整个组的空间，而不是指那个组的每个人的配额。
