5.6.5 Changing other file system attributes

NOTE:

Systems running in Portals compatibility mode cannot use the quota functionality. You will not be

able to change the quota options on a file system while the HP SFS system is running in Portals

compatibility mode.

To change file system attributes, perform the following steps:

Unmount the file system on all client nodes.

Stop the file system as shown in the following example, where the

data

file is system is stopped:

sfs> stop filesystem data

Do not proceed to the next step (running the

modify filesystem

command) until the file system is

stopped; the file system is stopped when all of the file system services are in the

stopped

down

state. See Section 3.7 for more information on the

stop filesystem

command.

When the file system is stopped, enter the

modify filesystem

command, as shown in the

following example:

sfs> modify filesystem data

Select an option:

1) Add OSTs
2) Change stripe size
3) Change stripe count
4) Change mount point
5) Change preferred servers
6) Change LUN mount options
7) Change interconnect
8) Change Lustre timeout
9) Change quota options
w) Rewrite LDAP configuration data
c) Cancel

Enter your choice [c]:

Select one of the options and follow the instructions for entering the new information. In this example,

the stripe size is changed:

Enter your choice [c]: 2

The stripe size of a filesystem is the default stripe size
for files created in the filesystem.
It must be a multiple of 4KB, and at least 4MB.

Please enter the stripe size of the filesystem [4MB]: 8MB

Changes made to data do not take effect until the
data file system is restarted using the start filesystem
command.

At this point, the

modify filesystem

command is finished. If you want to modify other attributes,

run the

modify filesystem

command again and change the appropriate attribute.

When you have finished modifying the attributes as required, start the file system as shown in the

following example:

sfs> start filesystem data

When the file system restarts, the client nodes can remount the file system. If a client node fails to

remount the file system, reboot the client node.
