...ing the files.. mostly, these hiccups are at 5-second intervals, so it may suggest that the ext3 default commit interval is the culprit, and the effect has diminished after i changed the commit interval to 1 second in the kernel code, under linux/fs/jbd/journal.c, the line changed was: journal->j_commit_interval = (HZ * 1); // originally HZ * 5. I have some questions at this point: 1. Is there any other way of modifying the commit interval? If possible I would like to take the commit interval modification out of the kernel and put it back in user level code.. 2. Are there other things that I should...

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

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

The following 6 patches cleanup the jbd code and kill about 200 lines. First of 4 patches can apply to 2.6.13-git8 and 2.6.13-mm2. The rest of them can apply to 2.6.13-mm2. fs/jbd/checkpoint.c | 179 +++++++++++-------------------------------- fs/jbd/commit.c | 101 ++++++++++-------------- fs/jbd/journal.c | 11 +- fs/jbd/revoke.c | 158
