Subject: Does raid5 have error handling while reading?
Date: Fri, 22 May 2009 16:10:07 +0800 [thread overview]
Message-ID: <691c243c0905220110y541ab523v5998b8054c89da60@mail.gmail.com> (raw)
I know that if the read request of raid5 is handled by
chunk_aligned_read, there is no error handling in raid5. But, if this
read request is not aligned, that's say, raid5 need stripe_head to
deal with this request. I find in the code of 2.6.27 that there is no
error handling if this read request fail, I remember in older kernel,
some operations should be done such as compute_block. Am I right?
