However for raid10, some layouts require\na bit of seeking to perform a resync, and allowing a larger buffer\nsize means that the seeking can be significantly reduced.\n\nThere is probably no real need to limit the amount of in-flight\nIO at all. Any shortage of memory will naturally reduce the\namount of buffer space available down to a set minimum, and any\nconcurrent normal IO will quickly cause resync IO to back off.\n\nThe only problem would be that normal IO has to wait for all resync IO\nto finish, so a very large amount of resync IO could cause unpleasant\nlatency when normal IO starts up.\n\nSo: increase RESYNC_DEPTH to allow 32Meg of buffer (if memory is\navailable) which seems to be a good amount. Also reduce the amount\nof memory reserved as there is no need to keep 2Meg just for resync if\nmemory is tight.\n\nThanks to Keld for the suggestion.\n\nCc: Keld Jørn Simonsen \u003ckeld@dkuug.dk\u003e\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit": "1e24b15b267293567a8d752721c7ae63f281325a", "tree": "ee63644d2dc59899e42ec0802c201140e3a92e5e", "parents": [ "63a16f90167850010864a9e8ebb71d216983090f", "388667bed591b2359713bb17d5de0cf56e961447" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 01 11:56:07 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 01 11:56:07 2008 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://neil.brown.name/md\n\n* \u0027for-linus\u0027 of git://neil.brown.name/md:\n md: raid10: wake up frozen array\n md: do not count blocked devices as spares\n md: do not progress the resync process if the stripe was blocked\n md: delay notification of \u0027active_idle\u0027 to the recovery thread\n md: fix merge error\n md: move async_tx_issue_pending_all outside spin_lock_irq\n" }, { "commit": "388667bed591b2359713bb17d5de0cf56e961447", "tree": "aa8a28db549719fecc540c9c0faf5bba58827ab2", "parents": [ "e542713529e323ff09d7aeb5806cf29f6f160f53" ], "author": { "name": "Arthur Jones", "email": "ajones@riverbed.com", "time": "Fri Jul 25 12:03:38 2008 -0700" }, "committer": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Fri Aug 01 12:55:14 2008 +1000" }, "message": "md: raid10: wake up frozen array\n\nWhen rescheduling a bio in raid10, we wake up\nthe md thread, but if the array is frozen, this\nwill have no effect.

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.

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 ?
