fsck.ocfs2: Unknown code while performing pass 1

This document (7006199) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 10 Service Pack 3


A basic fsck.ocfs2 with the -f switch fails and produces the following messages and error:

# fsck.ocfs2 -f /dev/sdc
Checking OCFS2 filesystem in /dev/sdc:
label: <NONE>
uuid: 4b 53 8f 5d c2 9e 4a e7 81 de c6 cf b9 da 2e 89

number of clusters: 2097152

/dev/sdc was run with -f, check forced.

Pass 1b: Determining ownership of multiply-claimed clusters
Pass 1c: Determining the names of inodes owning multiply-claimed clusters
fsck.ocfs2: Unknown code while performing pass 1


The problem is caused by an uninitialized variable.
The ocfs2-tools update to version-1.4.0-0.10.1 corrects the problem.
