Sometimes occurs that metadata cannot be loaded e.g. wrong check sum It can happen due to metadata update racing with mdmon condition. If mpb loading is tried again, it is loaded successfully. Try to load metadata again before really giving up. Signed-off-by: Adam Kwolek <redacted> --- super-intel.c | 10 ++++++++-- 1 files changed, 8 insertions(+), 2 deletions(-)
