The inode is finally deleted when the last node to iput\nthe inode sees that i_nlink\u003d\u003d0 and the MAYBE_ORPHANED flag is set.\n\nA problem arises if a node is forced to free dentry locks because of memory\npressure. If this happens, the node will no longer get downconvert\nnotifications for the dentries that have been unlinked on another node.\nIf it also happens that node is actively using the corresponding inode and\nhappens to be the one performing the last iput on that inode, it will fail\nto delete the inode as it will not have the MAYBE_ORPHANED flag set.\n\nThis patch fixes this shortcoming by introducing a periodic scan of the\norphan directories to delete such inodes. Care has been taken to distribute\nthe workload across the cluster so that no one node has to perform the task\nall the time.\n\nSigned-off-by: Srinivas Eeda \u003csrinivas.eeda@oracle.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "6ca497a83e592d64e050c4d04b6dedb8c915f39a", "tree": "0b9cd611d6d907881841eca73d12a7f3b85f1716", "parents": [ "9405dccfd3201d2b76e120949bec81ba8cfbd2d0" ], "author": { "name": "wengang wang", "email": "wen.gang.wang@oracle.com", "time": "Fri Mar 06 21:29:10 2009 +0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Fri Apr 03 11:39:25 2009 -0700" }, "message": "ocfs2: fix rare stale inode errors when exporting via nfs\n\nFor nfs exporting, ocfs2_get_dentry() returns the dentry for fh.\nocfs2_get_dentry() may read from disk when the inode is not in memory,\nwithout any cross cluster lock. this leads to the file system loading a\nstale inode.\n\nThis patch fixes above problem.\n\nSolution is that in case of inode is not in memory, we get the cluster\nlock(PR) of alloc inode where the inode in question is allocated from (this\ncauses node on which deletion is done sync the alloc inode) before reading\nout the inode itsself. then we check the bitmap in the group (the inode in\nquestion allcated from) to see if the bit is clear. if it\u0027s clear then it\u0027s\nstale. if the bit is set, we then check generation as the existing code\ndoes.\n\nWe have to read out the inode in question from disk first to know its alloc\nslot and allot bit. And if its not stale we read it out using ocfs2_iget().\nThe second read should then be from cache.\n\nAnd also we have to add a per superblock nfs_sync_lock to cover the lock for\nalloc inode and that for inode in question. this is because ocfs2_get_dentry()\nand ocfs2_delete_inode() lock on them in reverse order. nfs_sync_lock is locked\nin EX mode in ocfs2_get_dentry() and in PR mode in ocfs2_delete_inode(). so\nthat mutliple ocfs2_delete_inode() can run concurrently in normal case.\n\n[mfasheh@suse.com: build warning fixes and comment cleanups]\nSigned-off-by: Wengang Wang \u003cwen.gang.wang@oracle.com\u003e\nAcked-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "c74ff8bb2235d848beb67fcfddae71ecbe3f92b1", "tree": "516dd4c87a13c5a068fb47660488f52de486ddb2", "parents": [ "7dc102b737e9f49dac426161294cb2d326a97d8e" ], "author": { "name": "Sunil Mushran", "email": "sunil.mushran@oracle.com", "time": "Tue Feb 03 12:37:14 2009 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Thu Feb 26 11:51:09 2009 -0800" }, "message": "ocfs2: Cleanup the lockname print in dlmglue.c\n\nThe dentry lock has a different format than other locks.

This is called CANCELGRANT after the\nstatus code sent to the callback. fs/dlm does not provide this\ncallback, so dlmglue must be changed to live without it.\no2dlm_unlock_ast_wrapper() in stackglue now ignores CANCELGRANT calls.\n\nBecause dlmglue no longer sees CANCELGRANT, ocfs2_unlock_ast() no longer\nneeds to check for it. ocfs2_locking_ast() must catch that a cancel was\ntried and clear the cancel state.\n\nMaking these changes opens up a locking race. dlmglue uses the the\nOCFS2_LOCK_BUSY flag to ensure only one thread is calling the dlm at any\none time. But dlmglue must unlock the lockres before calling into the\ndlm. In the small window of time between unlocking the lockres and\ncalling the dlm, the downconvert thread can try to cancel the lock. The\ndownconvert thread is checking the OCFS2_LOCK_BUSY flag - it doesn\u0027t\nknow that ocfs2_dlm_lock() has not yet been called.\n\nBecause ocfs2_dlm_lock() has not yet been called, the cancel operation\nwill just be a no-op. There\u0027s nothing to cancel. With CANCELGRANT,\ndlmglue uses the CANCELGRANT callback to clear up the cancel state.\nWhen it comes around again, it will retry the cancel. Eventually, the\nfirst thread will have called into ocfs2_dlm_lock(), and either the\nlock or the cancel will succeed. The downconvert thread can then do its\ndownconvert.\n\nWithout CANCELGRANT, there is nothing to clean up the cancellation\nstate. The downconvert thread does not know to retry its operations.\nMore importantly, the original lock may be blocking on the other node\nthat is trying to cancel us. With neither able to make progress, the\nast is never called and the cancellation state is never cleaned up that\nway. dlmglue is deadlocked.\n\nThe OCFS2_LOCK_PENDING flag is introduced to remedy this window. It is\nset at the same time OCFS2_LOCK_BUSY is. Thus, the downconvert thread\ncan check whether the lock is cancelable. If not, it just loops around\nto try again. Once ocfs2_dlm_lock() is called, the thread then clears\nOCFS2_LOCK_PENDING and wakes the downconvert thread. Now, if the\ndownconvert thread finds the lock BUSY, it can safely try to cancel it.\nWhether the cancel works or not, the state will be properly set and the\nlock processing can continue.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "0abd6d1803b01c741430af270026d1d95a103d9c", "tree": "c1aca3d286990be6f9043e28ad0bacaf3443ef54", "parents": [ "6953b4c008628b945bfe0cee97f6e78a98773859" ], "author": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Tue Jan 29 16:59:56 2008 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Fri Apr 18 08:56:04 2008 -0700" }, "message": "ocfs2: Fill node number during cluster stack init\n\nIt doesn\u0027t make sense to query for a node number before connecting to the\ncluster stack.

If the versions do not match, two nodes cannot speak\nto each other and they disconnect. As a result, this provides no forward or\nbackwards compatibility.\n\nThis patch implements a simple protocol negotiation at the dlm level by\nintroducing a major/minor version number scheme for entities that\ncommunicate. Specifically, o2dlm has a major/minor version for interaction\nwith o2dlm on other nodes, and ocfs2 itself has a major/minor version for\ninteracting with the filesystem on other nodes.\n\nThis will allow rolling upgrades of ocfs2 clusters when changes to the\nlocking or network protocols can be done in a backwards compatible manner.\nIn those cases, only the minor number is changed and the negotatied protocol\nminor is returned from dlm join. In the far less likely event that a\nrequired protocol change makes backwards compatibility impossible, we simply\nbump the major number.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmark.fasheh@oracle.com\u003e\n" }, { "commit": "cf8e06f1a860d8680d6bb4ac8ec7d7724988e46f", "tree": "4705326641f39fdb1b97c925b55dae3c4634d5e0", "parents": [ "2fbe8d1ebe004425b4f7b8bba345623d2280be82" ], "author": { "name": "Mark Fasheh", "email": "mark.fasheh@oracle.com", "time": "Thu Dec 20 16:43:10 2007 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mark.fasheh@oracle.com", "time": "Fri Jan 25 15:05:43 2008 -0800" }, "message": "[PATCH 1/2] ocfs2: add flock lock type\n\nThis adds a new dlmglue lock type which is intended to back flock()\nrequests.\n\nSince these locks are driven from userspace, usage rules are much more\nliberal than the typical Ocfs2 internal cluster lock.
