-linux disk quotas per user management (quota)

I've organized the basics according to the ref link below Yes per user quota management steps
(The quota management by group is simplified)
I am finishing in Ubuntu server 12.04, other versions of Ubuntu and Linux should be no problem

(with any errors, please correct me, including typo)

<-> Preparation:

sudo apt-get Install quota

< two > by user name Quota steps are as follows:

1. Set the partition with quotas:/etc/fstab:
Like
UUID=5CE4F28A-23CE-464A-86E0-7CAA61503961/MNT/SDB3 ext4 Errors=remount-ro,usrquota 0 1

(This is required for partitions that require quotas)

2. Quotacheck-avu

3. Edquota-u Xiec (Xiec user name)
Default is 0 means no limit

Example:

Disk quotas for user Ramesh (UID.):  Filesystem           blocks       soft       hard     inodes     soft  Hard /dev/sda3           1419352          0          0       1686        0        0

(Front two 0 0 is the back of space management two 0 0 is I node management if you ignore it, keep it 0.
More than soft will notice more than hard will not add files, login or no problem! ）

4. Start the Quota service:
/etc/init.d/quota Start (in addition to auto-start the whole boot)
/etc/init.d/quota Status (view service status)

5. Update the quota partition check and notify the administrator:

#/etc/cron.daily/quotacheck:

/etc/init.d/quota stop

Quotacheck-avu

Etc/init.d/quota start
