<DIV><FONT face=Arial size=2>Dear All:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am building an Oracle 10G R2 cluster as outlined
in Jeffrey Hunter's article 'Build your own Oracle 10g Release 2 Cluster on
Linux and Firewire'. However I'm experiencing problems with the OCFS2 filesystem
on the shared drive. After the system boots up and the device is mounted to the
directory /u02/oradata/orcl, the kernel displays the error message "OCFS2: ERROR
(device sda1): ocfs2_meta_lock_update: Dinode # 17 has bad signature
KNODE01 File system is now read only due to the potential of on-disk
corruption. Please run fsck.ocfs2 once the file system is unmounted.".
</FONT><FONT face=Arial size=2>After running fsck.ocfs2 to fix the problem, the
same message appears again. I did notice this happens to dinode # 17 and 23
only. I upgraded ocfs2 to the latest version, 1.2.1.1, but the problem still
appears. I also checked the Maxtor drive using their Powermax disk utility and
it reported the drive is clean. Any help with this problem is
appreciated.</FONT></DIV>

in a Nspire NSP-ED352C external drive enclosure with Firewire (Oxford 911
chipset) and USB interfaces. </FONT></DIV>
