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 ?

This was done because the value of raid_disks is used to signal\nwhether array details have been provided by userspace (raid_disks \u003e 0) or must\nbe read from the devices (raid_disks \u003d\u003d 0).\n\nHowever for an array without persistent metadata (or with externally managed\nmetadata) this is the wrong thing to do. So we add a test in do_md_run to\ngive an error if raid_disks is zero for non-persistent arrays.\n\nThis requires that mddev-\u003epersistent is set corrently at this point, which it\ncurrently isn\u0027t for in-kernel autodetected arrays.\n\nSo set -\u003epersistent for autodetect arrays, and remove the settign in\nsuper_*_validate which is now redundant.\n\nAlso clear -\u003epersistent when stopping an array so it is consistently zero when\nstarting an array.\n\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": "c620727779f7cc8ea96efb71f0651a26349e59c1", "tree": "777abdad9c9ef10cb4df5c0efc736e6c64851ed8", "parents": [ "c303da6d713b87b7b3f999f5acce8ecc76ff1adb" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Wed Feb 06 01:39:52 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Feb 06 10:41:18 2008 -0800" }, "message": "md: allow a maximum extent to be set for resyncing\n\nThis allows userspace to control resync/reshape progress and synchronise it\nwith other activities, such as shared access in a SAN, or backing up critical\nsections during a tricky reshape.\n\nWriting a number of sectors (which must be a multiple of the chunk size if\nsuch is meaningful) causes a resync to pause when it gets to that point.\n\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": "c303da6d713b87b7b3f999f5acce8ecc76ff1adb", "tree": "5bd9852beea7b4d8a4cffe07657ca2ca3d71a3fc", "parents": [ "e691063a61f7f72a7d2882eb744b07a520cde23b" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Wed Feb 06 01:39:51 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Feb 06 10:41:18 2008 -0800" }, "message": "md: give userspace control over removing failed devices when external metdata in use\n\nWhen a device fails, we must not allow an further writes to the array until\nthe device failure has been recorded in array metadata.
