Description
I was just doing a quick test on DoM striping on a directory, and found something strange with the output of lfs getstripe. I created a PFL default layout on the directory and then copied files there. They all seem to show the lmm_layout_gen: 0 and a non-zero lmm_stripe_offset: field for the DoM components:
lcm_layout_gen: 4
lcm_mirror_count: 1
lcm_entry_count: 3
lcme_id: 1
lcme_mirror_id: 0
lcme_flags: init
lcme_extent.e_start: 0
lcme_extent.e_end: 1048576
lmm_stripe_count: 0
lmm_stripe_size: 1048576
lmm_pattern: mdt
lmm_layout_gen: 0
lmm_stripe_offset: 2
lmm_objects:
lcme_id: 2
lcme_mirror_id: 0
lcme_flags: init
lcme_extent.e_start: 1048576
lcme_extent.e_end: 67108864
lmm_stripe_count: 1
lmm_stripe_size: 1048576
lmm_pattern: raid0
lmm_layout_gen: 0
lmm_stripe_offset: 1
lmm_objects:
- 0: { l_ost_idx: 1, l_fid: [0x100000000:0x3:0x0] }
It seems like lmm_layout_gen: should always be non-zero for PFL components, and lmm_stripe_offset: should be zero, or not even printed for DoM components?
