That is, if the write was not\nstripe aligned.\n\nThe main algorithm behind the XOR engine is the 2 dimensional array:\n\tstruct __stripe_pages_2d.\nA drawing might save 1000 words\n---\n\n__stripe_pages_2d\n |\n n \u003d pages_in_stripe_unit;\n w \u003d group_width - parity;\n | pages array presented to the XOR lib\n | |\n V |\n __1_page_stripe[0].pages --\u003e [c0][c1]..[cw][c_par] \u003c---|\n | |\n __1_page_stripe[1].pages --\u003e [c0][c1]..[cw][c_par] \u003c---\n |\n... | ...\n |\n __1_page_stripe[n].pages --\u003e [c0][c1]..[cw][c_par]\n ^\n |\n data added columns first then row\n\n---\nThe pages are put on this array columns first. .i.e:\n\tp0-of-c0, p1-of-c0, ... pn-of-c0, p0-of-c1, ...\nSo we are doing a corner turn of the pages.\n\nNote that pages will zigzag down and left. but are put sequentially\nin growing order. So when the time comes to XOR the stripe, only the\nbeginning and end of the array need be checked. We scan the array\nand any NULL spot will be field by pages-to-be-read.\n\nThe FS that wants to support RAID5 needs to supply an\noperations-vector that searches a given page in cache, and specifies\nif the page is uptodate or need reading. All these pages to be read\nare put on a slave ore_io_state and synchronously read. All the pages\nof a stripe are read in one IO, using the scatter gather mechanism.\n\nIn write we constrain our IO to only be incomplete on a single\nstripe. Meaning either the complete IO is within a single stripe so\nwe might have pages to read from both beginning or end of the\nstrip. Or we have some reading to do at beginning but end at strip\nboundary. The left over pages are pushed to the next IO by the API\nalready established by previous work, where an IO offset/length\ncombination presented to the ORE might get the length truncated and\nthe user must re-submit the leftover pages. (Both exofs and NFS\nsupport this)\n\nBut any ORE user should make it\u0027s best effort to align it\u0027s IO\nbefore hand and avoid complications. A cached ore_layout-\u003estripe_size\nmember can be used for that calculation. (NOTE: that ORE demands\nthat stripe_size may not be bigger then 32bit)\n\nWhat else? Well read it and tell me.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n" }, { "commit": "a1fec1dbbc8db974d2582e4040590cebe72171e4", "tree": "9dcbe1933b7f40256f40393f3c86dbb16e8fb953", "parents": [ "3e335672e018c06e007f85a5d54afd721fb3d6d5" ], "author": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Wed Oct 12 18:42:22 2011 +0200" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Mon Oct 24 16:55:36 2011 -0700" }, "message": "ore: RAID5 read\n\nThis patch introduces the first stage of RAID5 support\nmainly the skip-over-raid-units when reading.

In the\nimplementation of that we have two subtly different meanings of NULL.\nNULL meaning there is no tag on a directory entry and NULL meaning\nwe don\u0027t care which namespace the lookup is performed for. This\nmultiple uses of NULL have resulted in subtle bugs (since fixed)\nin the code.\n\nCurrently it is only the bonding driver that needs to have an untagged\nfile in a tagged directory.\n\nTo untagle this mess I am adding support for tagged files to sysfs.\nModifying the bonding driver to implement bonding_masters as a tagged\nfile. Registering bonding_masters once for each network namespace.\nThen I am removing support for untagged entries in tagged sysfs\ndirectories.\n\nResulting in code that is much easier to reason about.\n\nSigned-off-by: Eric W.
