Function librbd_sys::rbd_create3 [−] [src]

pub unsafe extern "C" fn rbd_create3(
    io: rados_ioctx_t, 
    name: *const c_char, 
    size: uint64_t, 
    features: uint64_t, 
    order: *mut c_int, 
    stripe_unit: uint64_t, 
    stripe_count: uint64_t
) -> c_int

create new rbd image

The stripe_unit must be a factor of the object size (1 << order). The stripe_count can be one (no intra-object striping) or greater than one. The RBD_FEATURE_STRIPINGV2 must be specified if the stripe_unit != the object size and the stripe_count is != 1.

Arguments

  • io ioctx
  • name image name
  • size image size in bytes
  • features initial feature bits
  • order object/block size, as a power of two (object size == 1 << order)
  • stripe_unit stripe unit size, in bytes.
  • stripe_count number of objects to stripe over before looping @return 0 on success, or negative error code
