Bad-block functionality is in mdadm-3.3 but this has not been released yet. I was thinking about using it only once to create the array. However I am still missing the manual for mdadm-3.3, where is that? without that I don't know how I should launch it to create an array with bad blocks. Another question: are older kernels such as 3.0 capable to run an array created with bad-block-log, obviously without using the bad-block-log functionality? oh but that could be dangerous, couldn't it... Thank you A.
