Get/Set Strip Size

You can use lfs on client to getstripe size on files: 

[root@comp16 ~]$ lfs getstripe /mnt/lustre/
/mnt/lustre/
stripe_count:   1 stripe_size:    1048576 stripe_offset:  -1
/mnt/lustre/iorfile.00000001
lmm_stripe_count:   1
lmm_stripe_size:    1048576
lmm_stripe_offset:  0
	obdidx		 objid		objid		 group
	     0	            19	         0x13	             0

Set the stripe size and stripe count 

# Stripe count of 1 and stripe size of 1M
lfs setstripe /mnt/lustre/ -c 2 -s 1M

# Stripe count of 2 and stripe size of 4M
lfs setstripe /mnt/lustre/ -c 2 -s 4M
