[Ocfs2-users] kernel BUG at fs/inode.c:250

[Yassine Diallo]

Hello,

I've installed the latest available version of ocfs2 1.2.5.1 by building the
source since no rpm was available for my distro ( suse 10.2) running on
kernel
2.6.18.2-34.

I managed to compile and install the source. The whole ocfs2 stack is
running on my two small nodes and I manage to touch / cp / rm files and
makes them visible on both nodes. However if I start to launch the Oracle
clusterware installation , the OUI get stuck during the process of creating
the OCR files. I receive the following message in dmesg on one of the two
nodes :

I *believe* that it comes back to the following line in the ocfs source file
fs/inode.c

#ifdef INODE_HAS_BLKSIZE
        inode->i_blksize = (u32)osb->s_clustersize;
#endif

I had a look at the current known errors in the forums but could not find
anything back from it. How can I look further ?

thank you for your time
