Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] md: support stripe/offset mode in raid10 The "industry standard" DDF format allows for a stripe/offset layout where data is duplicated on different stripes. e.g. A B C D D A B C E F G H H E F G (columns are drives, rows are stripes, LETTERS are chunks of data). This is similar to raid10's 'far' mode, but not quite the same. So enhance 'far' mode with a 'far/offset' option which follows the layout of DDFs stripe/offset.

[PATCH] md: improve raid10 "IO Barrier" concept raid10 needs to put up a barrier to new requests while it does resync or other background recovery. The code for this is currently open-coded, slighty obscure by its use of two waitqueues, and not documented. This patch gathers all the related code into 4 functions, and includes a comment which (hopefully) explains what is happening.

[PATCH] md: raid10 read-error handling - resync and read-only Add in correct read-error handling for resync and read-only situations. When read-only, we don't over-write, so we need to mark the failed drive in the r10_bio so we don't re-try it. During resync, we always read all blocks, so if there is a read error, we simply over-write it with the good block that we found (assuming we found one). Note that the recovery case still isn't handled in an interesting way. There is nothing useful to do for the 2-copies case. If there are 3 or more copies, then we could try reading from one of the non-missing copies, but this is a bit complicated and very rarely would be used, so I'm leaving it for now.
