Because parameter set for the flags field ends in a 1, this is an indication that a full fsck is required:

flags 4101 mod 0 clean 3c 

In a CVM/CFS environment, a full fsck can only be performed on a file system that is unmounted from ALL  nodes in the cluster.

Resolution

Unmount the file system on all nodes, perform a full fsck, and then mount the file system on all nodes.

 

 

Issue/Introduction

CFS file system fails to mount on a node when full fsck flag is set on the file system.
