Cluster disk resource 'name ' has failed a file system check. Please check your disk configuration.
A file system check found corruption on the disk. This can happen during an IsAlive check.
Under certain circumstances, the Disk resource DLL runs chkdisk; if the DLL didn't run chkdisk, either run chkdisk or repair the volume by deleting the affected partition and recreating it. Then reinstall the cluster server.
