If there is an error, the relevant drive will be marked as\nFaulty, and that is enough to ensure correct handling of the error. So we\nfirst remove MD_RECOVERY_ERR, changing some of the uses of it to\nMD_RECOVERY_INTR.\n\nThen we cause the attempt to remove a non-faulty device from an array to\nfail (unless recovery is impossible as the array is too degraded). Then\nwhen remove_and_add_spares attempts to remove the devices on which\nrecovery can continue, it will fail, they will remain in place, and\nrecovery will continue on them as desired.\n\nIssue: If we are halfway through rebuilding a spare and another drive\nfails, and a new spare is immediately available, do we want to:\n 1/ complete the current rebuild, then go back and rebuild the new spare or\n 2/ restart the rebuild from the start and rebuild both devices in\n parallel.\n\nBoth options can be argued for. The code currently takes option 2 as\n a/ this requires least code change\n b/ this results in a minimally-degraded array in minimal time.\n\nCc: \"Eivind Sarto\" \u003civan@kasenna.com\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e7e72bf641b1fc7b9df6f40bd2c36dfccd8d647c", "tree": "81b1db5434c9635bf23fb40415056e10390cd692", "parents": [ "4920916f728fe3c51f54c25ab7b3d271254aab5a" ], "author": { "name": "Neil Brown", "email": "neilb@suse.de", "time": "Wed May 14 16:05:54 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 14 19:11:15 2008 -0700" }, "message": "Remove blkdev warning triggered by using md\n\nAs setting and clearing queue flags now requires that we hold a spinlock\non the queue, and as blk_queue_stack_limits is called without that lock,\nget the lock inside blk_queue_stack_limits.\n\nFor blk_queue_stack_limits to be able to find the right lock, each md\npersonality needs to set q-\u003equeue_lock to point to the appropriate lock.\nThose personalities which didn\u0027t previously use a spin_lock, us\nq-\u003e__queue_lock.

But\nI think stall is not preferable. If it occurs, even shutdown or reboot will\nfail because of resource busy.\n\nThe deadlock mechanism:\n\nThe r10bio_s structure has a \"remaining\" member to keep track of BIOs yet to\nbe handled when recovering. The \"remaining\" counter is incremented when\nbuilding a BIO in sync_request() and is decremented when finish a BIO in\nend_sync_write().\n\nIf building a BIO fails for some reasons in sync_request(), the \"remaining\"\nshould be decremented if it has already been incremented. I found a case\nwhere this decrement is forgotten.

One uses near-copies (so multiple\ncopies of a block are at the same or similar offsets of different\ndevices) and the other uses far-copies (so multiple copies of a block\nare stored a greatly different offsets on different devices). The point\nof far-copies is that it allows the first section (normally first half)\nto be layed out in normal raid0 style, and thus provide raid0 sequential\nread performance.\n\nUnfortunately, the read balancing in raid10 makes some poor decisions\nfor far-copies arrays and you don\u0027t get the desired performance. So\nturn off that bad bit of read_balance for far-copies arrays.\n\nWith this patch, read speed of an \u0027f2\u0027 array is comparable with a raid0\nwith the same number of devices, though write speed is ofcourse still\nvery slow.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b2d444d7ad975d555bb919601bcdc0e58975a40e", "tree": "963a29258af95f05dd28d9de0180ac9ef533aeed", "parents": [ "ba22dcbf106338a5c46d6979f9b19564faae3d49" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Tue Nov 08 21:39:31 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 09 07:56:38 2005 -0800" }, "message": "[PATCH] md: convert \u0027faulty\u0027 and \u0027in_sync\u0027 fields to bits in \u0027flags\u0027 field\n\nThis has the advantage of removing the confusion caused by \u0027rdev_t\u0027 and\n\u0027mddev_t\u0027 both having \u0027in_sync\u0027 fields.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d6065f7bf8bec170c9c56524a250093ce73ca5d9", "tree": "336c7db10aa8cee48386171e3de7569fca01dcfd", "parents": [ "9d88883e68f404d5581bd391713ceef470ea53a9" ], "author": { "name": "Suzanne Wood", "email": "suzannew@cs.pdx.edu", "time": "Tue Nov 08 21:39:27 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 09 07:56:37 2005 -0800" }, "message": "[PATCH] md: provide proper rcu_dereference / rcu_assign_pointer annotations in md\n\nAcked-by: \u003cpaulmck@us.ibm.com\u003e\nSigned-off-by: Suzanne Wood \u003csuzannew@cs.pdx.edu\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a362357b6cd62643d4dda3b152639303d78473da", "tree": "fe4ce823e638ded151edcb142f28a240860f0d33", "parents": [ "d72d904a5367ad4ca3f2c9a2ce8c3a68f0b28bf0" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Tue Nov 01 09:26:16 2005 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Tue Nov 01 09:26:16 2005 +0100" }, "message": "[BLOCK] Unify the seperate read/write io stat fields into arrays\n\nInstead of having -\u003eread_sectors and -\u003ewrite_sectors, combine the two\ninto -\u003esectors[2] and similar for the other fields.
