Ocfs2 users - Aug 2007 - OCFS file system change to READ-ONLY file system

We have OCFS 1.2.5-2 on Redhat AS 4.5.  This OCFS file
system have ORACLE RAC files put on it.

i t have been happen several times OCFS file system
change to READ-ONLY file system like:

1. ftp file transfer error 

2. when I issue "alter system switch logfile" on
sqlplus

Does there has way to avoid OCFS file system change to
READ-ONLY?

Thanks.

The file system is flipped to read only when the kernel module encounters
some disk meta data which it believe might be corrupt. Usually a message is
printed when this happens indicating precisely which blocks are in question.

Can you please post any messages you get in the system logs when this
happens?

Also, can you run:

	fsck.ocfs2 -fn <device>

against your file system and post the output here.

Thanks,

Is it possible, that they foret to extend OCFS FS to 10 nodes? As I 
remember, default setting have smaller # of nodes (in disk slots)?
