Please enter the LUN you wish to use [8]: 8
Please enter the preferred server for this OST LUN [south3]: south3
You are now asked to specify the primary usage of the file system, so that the system software can optimize
file system performance.
The file system can be optimized for the following I/O scenarios:
1) Predominantly large file streamed sequential access
2) Large numbers of smaller files
Please select its primary usage [1]:
You are now asked to specify mount options for the file system. Specify the mount options you want to use
for the MDS services. Accept the defaults for the mount options for the OST services.
Lustre can use any ext3 mount options to mount the MDS LUNs file systems.
Please enter the list of options for MDSs, or ? for help [acl,user_xattr]:
Lustre can use any ext3 mount options to mount the OST LUNs file systems.
Note: The extents option is recommended for OST LUNs.
Please enter the list of options for OSTs, or ? for help [extents,mballoc]:
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
decide to enable 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
