[Ocfs2-devel] Error message shows when create and rmdir

[Ling, Xiaofeng]

Try this on 2.6.6 for svn 1303, this also exist on prev version.

Two node with /ocfs mount to the same disk.
1.node 0: mkdir /ocfs/a
2.node 1: rmdir /ocfs/a
after a while, when the journal commited.
It shows:
(18503) commit_thread: flushed 1 transactions, releasing 3 locks
(18503) commit_thread: after optimization, 3 locks to release
(18503) ERROR at /home/xling/ocfs/ocfs2/src/bitmap.c, 408:
bitmap->validbits = 
0 but start = 277 and num = 1!

Do you get the last message on node 0 or node 1? I'm guessing node 1, as it
looks like the commit thread is dropping the last reference on the inode
(which is fine in and of itself). So you're probably in delete_inode dumping
the data for the directory. Can you reproduce this at will?

Yes,  seems it can be reproduced each time.
