That is not really very verbose – an example [mhebenst@ehs141 ~]$ lfs getstripe /lfs/lfs10s/mhebenst/IOR.00000001 /lfs/lfs10s/mhebenst/IOR.00000001 lmm_stripe_count: 1 lmm_stripe_size: 1048576 lmm_pattern: 1 lmm_layout_gen: 0 lmm_stripe_offset: 8 obdidx objid objid group 8 4989642 0x4c22ca 0
Does that mean the file is only present on OST8 of 11(there are 12 OSTs)? What if the stripesize 2 or higher? Will the distribution be exactly round robin over the listed OSTs?
