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": "90b08710e41a07d4ff0fb8940dcce3a552991a56", "tree": "8e45d1c6d9b4020099fd36781065bf8b8fdb76e4", "parents": [ "4f54b0e9485644a3c5fca2ae43bcbe7376825747" ], "author": { "name": "Bernd Schubert", "email": "bs@q-leap.de", "time": "Fri May 23 13:04:38 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat May 24 09:56:10 2008 -0700" }, "message": "md: allow parallel resync of md-devices.\n\nIn some configurations, a raid6 resync can be limited by CPU speed\n(Calculating P and Q and moving data) rather than by device speed.

Usually, the\nsequence is that someone calls submit_bh to submit IO on a buffer. The IO plugs\nthe queue and waits (to be possibly joined with other adjacent bios). Then, when\nthe caller calls wait_on_buffer(), it unplugs the queue and submits the IOs to\nthe disk.\n\nThis was happenning:\n\nWhen doing O_SYNC writes, function fsync_buffers_list() submits a list of\nbios to dm_raid1, the bios are added to dm_raid1 write queue and kmirrord is\nwoken up.\n\nfsync_buffers_list() calls wait_on_buffer(). That unplugs the queue, but\nthere are no bios on the device queue as they are still in the dm_raid1 queue.\n\nwait_on_buffer() starts waiting until the IO is finished.\n\nkmirrord is scheduled, kmirrord takes bios and submits them to the devices.\n\nThe submitted bio plugs the harddisk queue but there is no one to unplug it.\n(The process that called wait_on_buffer() is already sleeping.)\n\nSo there is a 3ms timeout, after which the queues on the harddisks are\nunplugged and requests are processed.\n\nThis 3ms timeout meant that in certain workloads (e.g. O_SYNC, 8kb writes),\ndm-raid1 is 10 times slower than md raid1.\n\nEvery time we submit something asynchronously via dm_io, we must unplug the\nqueue actually to send the request to the device.\n\nThis patch adds an unplug call to kmirrord - while processing requests, it keeps\nthe queue plugged (so that adjacent bios can be merged); when it finishes\nprocessing all the bios, it unplugs the queue to submit the bios.\n\nIt also fixes kcopyd which has the same potential problem. All kcopyd requests\nare submitted with BIO_RW_SYNC.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "a2aebe03be60ae4da03507a00d60211d5e0327c3", "tree": "9475bf530b36f3f4a26c8307d94b3c53787d9ef2", "parents": [ "a765e20eeb423d0fa6a02ffab51141e53bbd93cb" ], "author": { "name": "Mikulas Patocka", "email": "mpatocka@redhat.com", "time": "Thu Apr 24 22:10:42 2008 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Apr 25 13:26:56 2008 +0100" }, "message": "dm raid1: use timer\n\nThis patch replaces the schedule() in the main kmirrord thread with a timer.\nThe schedule() could introduce an unwanted delay when work is ready to be\nprocessed.\n\nThe code instead calls wake() when there\u0027s work to be done immediately, and\ndelayed_wake() after a failure to give a short delay before retrying.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "a765e20eeb423d0fa6a02ffab51141e53bbd93cb", "tree": "fc7279fa73a21518373e1ba2efad27dab89a2214", "parents": [ "2d1e580afe23287871529ce54429e249809525a1" ], "author": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Thu Apr 24 22:02:01 2008 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Apr 25 13:26:55 2008 +0100" }, "message": "dm: move include files\n\nPublish the dm-io, dm-log and dm-kcopyd headers in include/linux.\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "2d1e580afe23287871529ce54429e249809525a1", "tree": "82a0e8b442308c9b9bcf8f8d59c405950dd827d5", "parents": [ "0da336e5fab75c712ba8c67f3135d5a20528465f" ], "author": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Thu Apr 24 21:55:00 2008 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Apr 25 13:26:54 2008 +0100" }, "message": "dm kcopyd: rename\n\nRename kcopyd.[ch] to dm-kcopyd.[ch].\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "0da336e5fab75c712ba8c67f3135d5a20528465f", "tree": "8907bfc6db07ba73979df23d99424984aa02d3d7", "parents": [ "945fa4d283a3a472186c11028f6fea1e77a91d14" ], "author": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Thu Apr 24 21:43:52 2008 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Apr 25 13:26:53 2008 +0100" }, "message": "dm: expose macros\n\nMake dm.h macros and inlines available in include/linux/device-mapper.h\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "945fa4d283a3a472186c11028f6fea1e77a91d14", "tree": "99af5b3623665680417a61a43f5effcfbeba903b", "parents": [ "08d8757a4d52d21d825b9170af36f2696d1da1a8" ], "author": { "name": "Mikulas Patocka", "email": "mpatocka@redhat.com", "time": "Thu Apr 24 21:43:49 2008 +0100" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Apr 25 13:26:52 2008 +0100" }, "message": "dm kcopyd: remove redundant client counting\n\nRemove client counting code that is no longer needed.\n\nInitialization and destruction is made globally from dm_init and dm_exit and is\nnot based on client counts.

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. This causes a md_do_sync() deadlock\nbecause md_do_sync() waits for md_done_sync() called by end_sync_write(), but\nend_sync_write() never calls md_done_sync() because of the \"remaining\" counter\nmismatch.\n\nFor example, this problem would be reproduced in the following case:\n\nPersonalities : [raid10]\nmd0 : active raid10 sdf1[4] sde1[5](F) sdd1[2] sdc1[1] sdb1[6](F)\n 3919616 blocks 64K chunks 2 near-copies [4/2] [_UU_]\n [\u003e....................] recovery \u003d 2.2% (45376/1959808) finish\u003d0.7min speed\u003d45376K/sec\n\nThis case, sdf1 is recovering, sdb1 and sde1 are disabled.\nAn additional error with detaching sdd will cause a deadlock.\n\nmd0 : active raid10 sdf1[4] sde1[5](F) sdd1[6](F) sdc1[1] sdb1[7](F)\n 3919616 blocks 64K chunks 2 near-copies [4/1] [_U__]\n [\u003d\u003e...................] recovery \u003d 5.0% (99520/1959808) finish\u003d5.9min speed\u003d5237K/sec\n\n 2739 ?

We rely on \u0027flush_workqueue\u0027 to ensure that the\nmirror thread is complete and therefore, has requeued all writes\nin the failures list.\n\nBecause we are using flush_workqueue, we must ensure that no\nadditional \u0027queue_work\u0027 calls will produce additional I/O\nthat we need to requeue (because once we return from\npresuspend, we are unable to do anything about it). \u0027queue_work\u0027\nis called in response to the following functions:\n- complete_resync_work \u003d NA, recovery is stopped\n- rh_dec (mirror_end_io) \u003d NA, only calls \u0027queue_work\u0027 if it\n is ready to recover the region\n (recovery is stopped) or it needs\n to clear the region in the log*\n **this doesn\u0027t get called while\n suspending**\n- rh_recovery_end \u003d NA, recovery is stopped\n- rh_recovery_start \u003d NA, recovery is stopped\n- write_callback \u003d 1) Writes w/o failures simply call\n bio_endio -\u003e mirror_end_io -\u003e rh_dec\n (see rh_dec above)\n 2) Writes with failures are put on\n the failures list and queue_work is\n called**\n ** write_callbacks don\u0027t happen\n during suspend **\n- do_failures \u003d NA, \u0027queue_work\u0027 not called if suspending\n- add_mirror (initialization) \u003d NA, only done on mirror creation\n- queue_bio \u003d NA, 1) delayed I/O scheduled before flush_workqueue\n is called. 2) No more I/Os are being issued.\n 3) Re-attempted READs can still be handled.\n (Write completions are handled through rh_dec/\n write_callback - mention above - and do not\n use queue_bio.)\n\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "8f0205b798f926e2745de5fdebf0a8605c621de6", "tree": "3b0efdd8b666e507c2c7987ce6477064c2d4cc56", "parents": [ "72f4b314100bae85c75d8e4c6fec621ab44e777d" ], "author": { "name": "Jonathan Brassow", "email": "jbrassow@redhat.com", "time": "Fri Feb 08 02:11:32 2008 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Feb 08 02:11:32 2008 +0000" }, "message": "dm raid1: handle recovery failures\n\nThis patch adds the calls to \u0027fail_mirror\u0027 if an error occurs during\nmirror recovery (aka resynchronization). \u0027fail_mirror\u0027 is responsible\nfor recording the type of error by mirror device and ensuring an event\ngets raised for the purpose of notifying userspace.\n\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "72f4b314100bae85c75d8e4c6fec621ab44e777d", "tree": "6dc5e860e8a4acab2e047f31391d0c8fdf366ff7", "parents": [ "d74f81f8adc504a23be3babf347b9f69e9389924" ], "author": { "name": "Jonathan Brassow", "email": "jbrassow@redhat.com", "time": "Fri Feb 08 02:11:29 2008 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Feb 08 02:11:29 2008 +0000" }, "message": "dm raid1: handle write failures\n\nThis patch gives mirror the ability to handle device failures\nduring normal write operations.\n\nThe \u0027write_callback\u0027 function is called when a write completes.\nIf all the writes failed or succeeded, we report failure or\nsuccess respectively. If some of the writes failed, we call\nfail_mirror; which increments the error count for the device, notes\nthe type of error encountered (DM_RAID1_WRITE_ERROR), and\nselects a new primary (if necessary). Note that the primary\ndevice can never change while the mirror is not in-sync (IOW,\nwhile recovery is happening.) This means that the scenario\nwhere a failed write changes the primary and gives\nrecovery_complete a chance to misread the primary never happens.\nThe fact that the primary can change has necessitated the change\nto the default_mirror field. We need to protect against reading\ngarbage while the primary changes. We then add the bio to a new\nlist in the mirror set, \u0027failures\u0027. For every bio in the \u0027failures\u0027\nlist, we call a new function, \u0027__bio_mark_nosync\u0027, where we mark\nthe region \u0027not-in-sync\u0027 in the log and properly set the region\nstate as, RH_NOSYNC. Userspace must also be notified of the\nfailure. This is done by \u0027raising an event\u0027 (dm_table_event()).\nIf fail_mirror is called in process context the event can be raised\nright away. If in interrupt context, the event is deferred to the\nkmirrord thread - which raises the event if \u0027event_waiting\u0027 is set.\n\nBackwards compatibility is maintained by ignoring errors if\nthe DM_FEATURES_HANDLE_ERRORS flag is not present.\n\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "d74f81f8adc504a23be3babf347b9f69e9389924", "tree": "4a687e400479ad330bb36ded54012cd8b8b84ecf", "parents": [ "4f7f5c675fd6bacaae3c67be44de872dcff0e3b7" ], "author": { "name": "Milan Broz", "email": "mbroz@redhat.com", "time": "Fri Feb 08 02:11:27 2008 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Feb 08 02:11:27 2008 +0000" }, "message": "dm snapshot: combine consecutive exceptions in memory\n\nProvided sector_t is 64 bits, reduce the in-memory footprint of the\nsnapshot exception table by the simple method of using unused bits of\nthe chunk number to combine consecutive entries.\n\nSigned-off-by: Milan Broz \u003cmbroz@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n" }, { "commit": "4f7f5c675fd6bacaae3c67be44de872dcff0e3b7", "tree": "5825966577a4018047bc126922b1f815af905348", "parents": [ "a25eb9446ad50027bc2082386e5358bedad087ed" ], "author": { "name": "Brian Wood", "email": "brian.j.wood@intel.com", "time": "Fri Feb 08 02:11:24 2008 +0000" }, "committer": { "name": "Alasdair G Kergon", "email": "agk@redhat.com", "time": "Fri Feb 08 02:11:24 2008 +0000" }, "message": "dm: stripe enhanced status return\n\nThis patch adds additional information to the status line.
