Everytime I try to start ocfs2 or mount a filesystem, I get the following error: "mount.ocfs2: Bad magic number in superblock while opening device /dev/emcpowera1" This is a 2 node system, and the other node is working fine. I just had a problem where someone inadvertently changed the kernel on me, but I changed it back, and now it won't mount. I even tried to reinstall the ocfs2 but it didn't seem to work. Any ideas? Thanks in advance, Alison Sanchez ***************************************** [root@tap1d2 init.d]# ./ocfs2 start Starting Oracle Cluster File System (OCFS2) mount.ocfs2: Bad magic number in superblock while opening device /dev/emcpowera1 [FAILED] [root@tap1d2 init.d]# rpm -qa |grep ocfs2 ocfs2console-1.2.4-1 ocfs2-tools-1.2.4-1 ocfs2-2.6.9-42.ELsmp-1.2.5-1 ocfs2-tools-devel-1.2.4-1 ocfs2-tools-debuginfo-1.2.4-1 [root@tap1d2 init.d]# uname -a Linux tap1d2 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux [root@tap1d2 init.d]# -------------- next part -------------- A non-text attachment was scrubbed...

Do: # mounted.ocfs2 -d Does the volume show up?
