Creating and modifying file systems5–40

• If the file system was created on a system running HP SFS Version 2.2, proceed to Section 5.7.2.5 to

activate quota functionality on the file system.

5.7.2.4 Step 4: Configuring user and group information on a file system

This step applies only to file systems that were originally created when the system was running a version of

the HP SFS software earlier than Version 2.2; if your file system was created on a system running HP SFS

Version 2.2, skip this step.

On a client node that has mounted the file system, enter the command shown in the following example on

a client node that has been configured as described in Section 5.7.2.3, and where the file system is

mounted. Specify the mount point for the file system:

lfs quotachown /data

Note that you only need to run this command once, on one client node. When the lfs quotachown

command has been run once against a file system, as described here, the necessary user and group

information is configured on the file system for all client nodes.

Proceed to Section 5.7.2.5 to activate quota functionality on the file system.

5.7.2.5 Step 5: Activating quota functionality on a file system

To activate user and group quotas on the file system, enter the lfs quotacheck command shown in the

following example on a client node. The client node must be configured as described in Section 5.7.2.3,

and the file system must be mounted on the client node. Specify the mount point for the file system:

CAUTION: Do not run the lfs quotacheck command while there are applications performing

I/O operations on the file system.

# lfs quotacheck -ug /data

Note that you only need to run this command once, on one client node. When the lfs quotacheck

command has been run once against a file system, as described here, quotas are enabled on the file system

for all client nodes.

TIP: You can also use the lfs quotacheck command at any time to check quota information on the file

system—see Section 5.7.3 for more information.

Proceed to Section 5.7.2.6 to specify quota limits for users and/or groups.

5.7.2.6 Step 6: Specifying quota limits for users and/or groups

After quota functionality has been enabled and activated as described in Section 5.7.2.2 through

Section 5.7.2.5, a given user or group still has no limits until the quotas have been set using lfs setquota

command (on a client node). You must now set these limits, as described here.

The syntax of the lfs setquota command is as follows:

lfs setquota -u user 0 block_hardlimit 0 inode_hardlimit mountpoint

lfs setquota -g group 0 block_hardlimit 0 inode_hardlimit mountpoint

Where:

block_hardlimit Specifies the total file size in blocks that the user or group can create in the

file system. A value of 0 (zero) indicates that no limit is to be imposed.

inode_hardlimit Specifies the number of inodes that can be created by the user or group in

the file system. A value of 0 (zero) indicates that no limit is to be imposed.
