/Test directory 777 50 m/user

1. Enable the partition Disk Quota Function

Temporary settings: Run mount-o remount, usrquota/test

Permanent settings: edit the/etc/fstab file and mark the usrquota [user quota] Or kgquota [user group quota, not commonly used] on the Mount attribute.

/Dev/sdb1/test ext4 defaults, usrquota 1 2

2. Create a quota database

Quotacheck-cvuga [quota, quota, quota]

-C create

-V: Show Details

-U creates a detection user quota

-G: create a user group quota for detection.

-A: detects all partitions.

Quotacheck-cvu/test # create only the user quota, and accurate to/test Partition

After you run this command, two files, aquota. user and aquota. groups, will be created.

-If SELinux is enabled, the command may fail to be executed.

Solution-Disable SELinux

Setenforce 0

Getenforce

Then run quotacheck-cvu/test.

OK!

3. Enable the quota Function

Quotaon [partition name]

Example: quotaon/test

[Disable the quota function: quotaoff partition name]

Iv. edit user quota

The edquota user name enters the user quota editing mode.

For example, edquota hadoop

Format description: blocks (kb) soft hard limits the size of the user's Space

Inodes soft hard limits the number of files created by the user]

Soft limit: defines the amount of disk space that a user can use. When the user exceeds this limit, the user will receive a warning that the quota is exceeded.

You can use edquota-t to set the grace period.

Grace period: defines the duration for users to use their file systems under Soft Limits

Hard limit: when a user attempts to store a file in a directory that has exceeded the limit value, the user reports a file system error and cannot create a file.

In fact, only the limit in blocks can be set: hadoop users can only use 50 M, as shown in

[Edquota-g user group name edit user group quota]

5. If multiple users need to copy the user quota

Edquota-p template user copying user 1 copying user 2... copying user n

Vi. Detection

VII. View quota Information

Quota [user name] # view the user's quota usage. You can view your disk quota without adding a user name.

Repquota-a or repquota/test # The administrator can view the quota information.
