The only notable thing was\nthat the xfsaild was trying to be active during the pauses, but\nmaking no progress. It was running exactly 20 times a second (on the\n50ms no-progress backoff), and the number of pushbuf events was\nconstant across this time as well. IOWs, the xfsaild appeared to be\nstuck on buffers that it could not push out.\n\nFurther investigation indicated that it was trying to push out inode\nbuffers that were pinned and/or locked. The xfsbufd was also getting\nwoken at the same frequency (by the xfsaild, no doubt) to push out\ndelayed write buffers. The xfsbufd was not making any progress\nbecause all the buffers in the delwri queue were pinned. This scan-\nand-make-no-progress dance went one in the trace for some seconds,\nbefore the xfssyncd came along an issued a log force, and then\nthings started going again.\n\nHowever, I noticed something strange about the log force - there\nwere way too many IO\u0027s issued. 516 log buffers were written, to be\nexact. That added up to 129MB of log IO, which got me very\ninterested because it\u0027s almost exactly 25% of the size of the log.\nHe delayed logging code is suppose to aggregate the minimum of 25%\nof the log or 8MB worth of changes before flushing. That\u0027s what\nreally puzzled me - why did a log force write 129MB instead of only\n8MB?\n\nEssentially what has happened is that no CIL pushes had occurred\nsince the previous tail push which cleared out 25% of the log space.\nThat caused all the new transactions to block because there wasn\u0027t\nlog space for them, but they kick the xfsaild to push the tail.\nHowever, the xfsaild was not making progress because there were\nbuffers it could not lock and flush, and the xfsbufd could not flush\nthem because they were pinned. As a result, both the xfsaild and the\nxfsbufd could not move the tail of the log forward without the CIL\nfirst committing.\n\nThe cause of the problem was that the background CIL push, which\nshould happen when 8MB of aggregated changes have been committed, is\nbeing held off by the concurrent transaction commit load. The\nbackground push does a down_write_trylock() which will fail if there\nis a concurrent transaction commit holding the push lock in read\nmode. With 8 CPUs all doing transactions as fast as they can, there\nwas enough concurrent transaction commits to hold off the background\npush until tail-pushing could no longer free log space, and the halt\nwould occur.\n\nIt should be noted that there is no reason why it would halt at 25%\nof log space used by a single CIL checkpoint. This bug could\ndefinitely violate the \"no transaction should be larger than half\nthe log\" requirement and hence result in corruption if the system\ncrashed under heavy load. This sort of bug is exactly the reason why\ndelayed logging was tagged as experimental....\n\nThe fix is to start blocking background pushes once the threshold\nhas been exceeded. Rework the threshold calculations to keep the\namount of log space a CIL checkpoint can use to below that of the\nAIL push threshold to avoid the problem completely.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Alex Elder \u003caelder@sgi.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "d1f3e68efb4c98fa229b39ff09a8984ef16cafa4", "tree": "48191a1e73f1afd1235331ce1597637ed71193aa", "parents": [ "cb9cae0395d70fc4539f6904c11d3a14c0001006", "5dad6c39d156fbbde0b0ef170d9173feffdeb546" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Sep 24 14:08:15 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Sep 24 14:08:15 2010 -0700" }, "message": "Merge branch \u0027upstream-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2\n\n* \u0027upstream-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2:\n o2dlm: force free mles during dlm exit\n ocfs2: Sync inode flags with ext2.\n ocfs2: Move \u0027wanted\u0027 into parens of ocfs2_resmap_resv_bits.\n ocfs2: Use cpu_to_le16 for e_leaf_clusters in ocfs2_bg_discontig_add_extent.\n ocfs2: update ctime when changing the file\u0027s permission by setfacl\n ocfs2/net: fix uninitialized ret in o2net_send_message_vec()\n Ocfs2: Handle empty list in lockres_seq_start() for dlmdebug.c\n Ocfs2: Re-access the journal after ocfs2_insert_extent() in dxdir codes.\n ocfs2: Fix lockdep warning in reflink.\n ocfs2/lockdep: Move ip_xattr_sem out of ocfs2_xattr_get_nolock.\n" }, { "commit": "5dad6c39d156fbbde0b0ef170d9173feffdeb546", "tree": "4e2f118c66f65746dec2c04ab2b792100b6b0e36", "parents": [ "0000b862027d624ac564609b87c1aa4d14dd1e46" ], "author": { "name": "Srinivas Eeda", "email": "srinivas.eeda@oracle.com", "time": "Tue Sep 21 16:27:26 2010 -0700" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Thu Sep 23 14:16:53 2010 -0700" }, "message": "o2dlm: force free mles during dlm exit\n\nWhile umounting, a block mle doesn\u0027t get freed if dlm is shutdown after\nmaster request is received but before assert master.

Backing device of such inodes\n(zero_bdi, etc.) is however unable to handle dirty inodes and thus\n__mark_inode_dirty complains. In fact, inode should be rather dirtied\nagainst backing device of the filesystem holding it. This is generally a\ngood rule except for filesystems such as \u0027bdev\u0027 or \u0027mtd_inodefs\u0027. Inodes\nin these pseudofilesystems are referenced from ordinary filesystem\ninodes and carry mapping with real data of the device.

We distinguish these filesystems by checking whether sb-\u003es_bdi\npoints to a non-trivial backing device or not.\n\nExample: Assume we have an ext3 filesystem on /dev/sda1 mounted on /.\nThere\u0027s a device inode A described by a path \"/dev/sdb\" on this\nfilesystem. This inode will be dirtied against backing device \"8:0\"\nafter this patch. bdev filesystem contains block device inode B coupled\nwith our inode A. When someone modifies a page of /dev/sdb, it\u0027s B that\ngets dirtied and the dirtying happens against the backing device \"8:16\".\nThus both inodes get filed to a correct bdi list.\n\nCc: stable@kernel.org\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "371d217ee1ff8b418b8f73fb2a34990f951ec2d4", "tree": "74d5e95a0aa85b8a8b94621b247a78eb527ce609", "parents": [ "976e48f8a5b02fc33f3e5cad87fb3fcea041a49c" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Tue Sep 21 11:49:01 2010 +0200" }, "committer": { "name": "Jens Axboe", "email": "jaxboe@fusionio.com", "time": "Wed Sep 22 09:48:47 2010 +0200" }, "message": "char: Mark /dev/zero and /dev/kmem as not capable of writeback\n\nThese devices don\u0027t do any writeback but their device inodes still can get\ndirty so mark bdi appropriately so that bdi code does the right thing and files\ninodes to lists of bdi carrying the device inodes.\n\nCc: stable@kernel.org\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "19746cad00a00a7a2e3eb0640d317d6e7c2e8cc0", "tree": "3dfd66dce28b3b02f7e293b28b57191ca23f691c", "parents": [ "0ffe37de76a57ba38d960e370c2f8f1d799c94a1", "be4f104dfd3b5e3ae262bff607965cfc38027dec" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 21 11:20:10 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 21 11:20:10 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:\n ceph: select CRYPTO\n ceph: check mapping to determine if FILE_CACHE cap is used\n ceph: only send one flushsnap per cap_snap per mds session\n ceph: fix cap_snap and realm split\n ceph: stop sending FLUSHSNAPs when we hit a dirty capsnap\n ceph: correctly set \u0027follows\u0027 in flushsnap messages\n ceph: fix dn offset during readdir_prepopulate\n ceph: fix file offset wrapping at 4GB on 32-bit archs\n ceph: fix reconnect encoding for old servers\n ceph: fix pagelist kunmap tail\n ceph: fix null pointer deref on anon root dentry release\n" }, { "commit": "112d421df2fddc0278584b084f4fcfedd144c5f4", "tree": "29ae7aef63427f4163f25222e4712b08a80703c7", "parents": [ "151b6a5f1d4c547c92ec67a5a6fedc16f435956e" ], "author": { "name": "Jan Harkes", "email": "jaharkes@cs.cmu.edu", "time": "Fri Sep 17 23:26:01 2010 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Sep 19 11:03:09 2010 -0700" }, "message": "Coda: mount hangs because of missed REQ_WRITE rename\n\nCoda\u0027s REQ_* defines were renamed to avoid clashes with the block layer\n(commit 4aeefdc69f7b: \"coda: fixup clash with block layer REQ_*\ndefines\").\n\nHowever one was missed and response messages are no longer matched with\nrequests and waiting threads are no longer woken up.
