kcopyd work. kcopyd is responsible for copying an\nassigned section of disk to one or more other disks. The\n\u0027DM_KCOPYD_IGNORE_ERROR\u0027 flag affects kcopyd in the following way:\n\nWhen not set:\nkcopyd will immediately stop the copy operation when an error is\nencountered.\n\nWhen set:\nkcopyd will try to proceed regardless of errors and try to continue\ncopying any remaining amount.\n\nSince dm-raid1 tracks regions of the address space that are (or\nare not) in sync and it now has the ability to handle these\nerrors, we can safely enable this optimization.

leaves us\nwith a problem because we can sleep on memalloc while holding the\nrcu lock.\n\nThe rcu lock is only needed while walking the linked list as\nuninteresting devices (failed or spares) can be removed at any time.\n\nSo only take the rcu lock while actually walking the linked list.\nTake a refcount on the rdev during the time when we drop the lock\nand do the memalloc to start IO.\nWhen we return to the locked code, all the interesting devices\non the list will not have moved, so we can simply use\nlist_for_each_continue_rcu to pick up where we left off.\n\nSigned-off-by: NeilBrown

lock.\nThe main reason for this is probably to ensure all dirty buffers\nare flushed (invalidate_partition calls fsync_bdev).\n\nHowever if any dirty buffers are found, it will almost certainly cause\na deadlock as starting writeout will require an update to the\nsuperblock, and performing that updates requires taking the mddev\nlock - which is already held.\n\nThis deadlock can be demonstrated by running \"reboot -f -n\" with\na root filesystem on md/raid, and some dirty buffers in memory.\n\nAll other calls to stop an array should already happen after a flush.\nThe normal sequence is to stop using the array (e.g. umount) which\nwill cause __blkdev_put to call sync_blockdev. Then open the\narray and issue the STOP_ARRAY ioctl while the buffers are all still\nclean.\n\nSo this invalidate_partition is normally a no-op, except for one case\nwhere it will cause a deadlock.\n\nSo remove it.\n\nThis patch possibly addresses the regression recored in\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d11460\nand\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d11452\n\nthough it isn\u0027t yet clear how it ever worked.\n\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit": "56ac36d722d0d27c03599d1245ac0ab59e474e5c", "tree": "e65f4d860549532a570b92995906f3c3dec9c529", "parents": [ "0310fa216decc3ecfab41f327638fa48a81f3735" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Aug 07 10:02:47 2008 -0700" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Aug 07 10:02:47 2008 -0700" }, "message": "md: cancel check/repair requests when recovery is needed\n\nIf a \u0027repair\u0027 is requested when an array is in a position to \u0027recover\u0027 raid1\nwill perform the repair while md believes a recovery is happening.

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.

modifications and most access to the mddev-\u003edisks list are made\nunder the reconfig_mutex lock. However there are three places where\nthe list is walked without any locking. If a reconfig happens at this\ntime, havoc (and oops) can ensue.\n\nSo use RCU to protect these accesses:\n - wrap them in rcu_read_{,un}lock()\n - use list_for_each_entry_rcu\n - add to the list with list_add_rcu\n - delete from the list with list_del_rcu\n - delay the \u0027free\u0027 with call_rcu rather than schedule_work\n\nNote that export_rdev did a list_del_init on this list. In almost all\ncases the entry was not in the list anymore so it was a no-op and so\nsafe. It is no longer safe as after list_del_rcu we may not touch\nthe list_head.\nAn audit shows that export_rdev is called:\n - after unbind_rdev_from_array, in which case the delete has\n already been done,\n - after bind_rdev_to_array fails, in which case the delete isn\u0027t needed.\n - before the device has been put on a list at all (e.g. in\n add_new_disk where reading the superblock fails).\n - and in autorun devices after a failure when the device is on a\n different list.\n\nSo remove the list_del_init call from export_rdev, and add it back\nimmediately before the called to export_rdev for that last case.\n\nNote also that -\u003esame_set is sometimes used for lists other than\nmddev-\u003elist (e.g. candidates). In these cases rcu is not needed.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit": "f2ea68cf42aafdd93393b6b8b20fc3c2b5f4390c", "tree": "00b025b91898ff32dba742b5075dd290fec4dc91", "parents": [ "d6e2215052810678bc9782fd980b52706fc71f50" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Mon Jul 21 17:05:25 2008 +1000" }, "committer": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Mon Jul 21 17:05:25 2008 +1000" }, "message": "md: only count actual openers as access which prevent a \u0027stop\u0027\n\nOpen isn\u0027t the only thing that increments -\u003eactive. e.g. reading\n/proc/mdstat will increment it briefly.
