I am new user of Lustre file system and have issue with configuration  after installation Lustre file system.
When tried  to configure ,I got error message,output is below:

LustreSLES11:/dev # mkfs.lustre --fsname=temp  --device-size=100000 --mgs --mdt /dev/sdb

   Permanent disk data:
Target:     temp-MDTffff
Index:      unassigned
Lustre FS:  temp
Mount type: ldiskfs

              (MDT MGS needs_index first_time update )
Persistent mount opts: iopen_nopriv,user_xattr,errors=remount-ro

mkfs.lustre: Unable to mount /dev/loop0: No such device
Is the ldiskfs module available?

mkfs.lustre FATAL: failed to write local files
mkfs.lustre: exiting with 19 (No such device)
LustreSLES11:/dev # 

Can anybody help me with this issue?

Thanks and regards
