[Ocfs2-devel] Hang issue when change the dir attribute in a cluster enviornment

[Chen, Yukun]

Hi All

         On kernel 2.6.6, I get a system hang when change dir attribute.
Steps to reproduce:

         On node 1:

1.       mount to /ocfs2

2.       create dir /ocfs2/foo in mode 0666

 

On node 2:

1.       mount to /ocfs2

2.       chmod 0766 /ocfs2/foo

 

Then, get a system hang on node 2. The error log is as follows:

Oracle Cluster FileSystem x y (build z)
ocfs2: hostname is westvile2
sectbits=9, clusterbits=12, dirbits=17, filebits=9
ocfs2: Adding west1 (node 0) to clustered device (8,34)

It seems there is a lock error when change the dir attribute. Any idea
on it?

Thanx.
