Hi, We are running a server as an nfs head connect to a clariion, every couple of days we have our box fall over with the following msg in syslog. Has anyone had this happen to there boxen? rhel4 u4 May 8 12:23:52 ruchba kernel: Assertion failure in log_do_checkpoint() at fs/jbd/checkpoint.c:363: "drop_count != 0 || cleanup_ret != 0" May 8 12:23:52 ruchba kernel: ------------[ cut

Hello. I found bugs on error handlings in the functions arround the ext3 file system, which cause inadequate completions of synchronous write I/O operations when disk I/O failures occur. Both 2.4 and 2.6 have this problem. I carried out following experiment: 1. Mount a ext3 file system on a SCSI disk with ordered mode. 2. Open a file on the file system with O_SYNC|O_RDWR|O_TRUNC|O_CREAT

This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked. Theodore Ts'o (3): jbd2: Use

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call

jbd2_journal_restart() would restart a handle. In this function, it calls start_this_handle(). Before calling start_this_handle()?subtract 1 from transaction->t_updates. If start_this_handle() succeeds, transaction->t_updates increases by 1 in it. But if start_this_handle() fails, transaction->t_updates does not increase. So, when commit the handle's transaction in

This patch adds jbd_lock_bh_state() and jbd_unlock_bh_state() around accessses to jh->b_committed_data.

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza
