In "lustre/doc/lfs-getstripe.1": .BR --ost | -O Print the starting OST index for the file layout. It is the same with -i option: .BR --stripe-index | -i Print the starting OST index for the file layout.
"Print the starting OST index for the file layout." is not "-O" would do. Actually, "lfs getstrip O lustre0-OST0000" would print the information of the stripes located only on OST0000, and ignore the other stripes:
