Description

current output:

$ mkdir /mnt/lustre/test 
$ lfs getdirstripe /mnt/lustre/test
lmv_stripe_count: 0 lmv_stripe_offset: 0 lmv_hash_type: none
mdtidx           FID[seq:oid:ver]

expected output:

$ lfs getdirstripe /mnt/lustre/test
lmv_stripe_count: 0 lmv_stripe_offset: 0 lmv_hash_type: none

example where header is needed:

$ lfs setdirstripe -c2 /mnt/lustre/test2
$ lfs getdirstripe /mnt/lustre/test2
lmv_stripe_count: 2 lmv_stripe_offset: 1 lmv_hash_type: crush
mdtidx           FID[seq:oid:ver]
     1           [0x240000400:0x2:0x0]
     0           [0x200000401:0x2:0x0]
