Creating a file System — SFS20 storage

5–25

You are now asked to enter the stripe count for the file system.

The stripe count of a filesystem refers to the number of OST services a newly
created file will be striped across by default. (1 to 6; 0=1)

Please enter the stripe count of the filesystem [1]:

You are now asked to specify the interconnects that are to be used for file system I/O operations.

Lustre can use various interconnects for file systems I/O.
Valid interconnects are: tcp,gm,elan,vib
Those currently accessible are: tcp,gm

Please enter the list of interconnects to use [gm,tcp]:

You are now asked whether you want to enable quotas for users and/or groups on the file system. If you

are enabling quotas on the file system, HP strongly recommends that you accept the default values for the

quota options. (For quotas to come into effect, you must also configure quotas on the file system, as

described in Section 5.7.2.) )

Lustre can manage inode and disk space quotas.
Do you want to enable quotas for this file system? (y/n) [y]

Quotas support has several possible options.
Please enter quota options, or ? for help [quotaon=ug]

When you have finished specifying all of the file system information, the specifications for the new file system

are displayed, and you are asked to confirm that the specifications are correct.

This is the filesystem that will be created:

Filesystem Name: data
Mountpoint: /usr/data/
Stripe Size: 4096kb
Stripe Count: 1
MDS mount opts: acl,user_xattr
OST mount opts: extents,mballoc
Quota options: quotaon=ug
Interconnects: tcp,gm

MDS LUN(s):
LUN Array Controller Role Size(GB) Preferred Server Backup Server
--- ----- ---------- ---- -------- ---------------- -------------
3 1 scsi-1/1 mds 1050 south2 south1
5 2 scsi-2/1 mds 1050 south2 south1

OST LUN(s):
LUN Array Controller Role Size (GB) Preferred Server Backup Server
--- ----- ---------- ---- --------- ---------------- -------------
8 3 scsi-1/1 ost 1050 south3 south4
11 4 scsi-1/2 ost 1050 south4 south3
13 5 scsi-2/1 ost 1050 south3 south4
15 6 scsi-2/2 ost 1050 south4 south3
17 7 scsi-1/1 ost 1050 south5 south6
19 8 scsi-1/2 ost 1050 south6 south5
21 9 scsi-2/1 ost 1050 south5 south6
23 10 scsi-2/2 ost 1050 south6 south5

Is this correct? [yes]: yes
Would you like to create this filesystem? []: yes

TIP:

If you enter

, the file system is not created, but a script that can be used to create the file system is

displayed on the screen. You can capture this script and use it at a later time (see Section 5.2.3.2).

The

create filesystem

command then creates the file system. This may take some time, as each OST

service must be formatted. When the file system has been created, proceed to Section 5.2.4 to back up the

system database.
