%s could not read from block offset devid/blknum %u/%llu. Device may be missing in vset.

If a Veritas File System (VxFS) file system is larger than the Volume Manager volume on which it is being mounted, the mount fails. Before you mount the file system, you are prompted to run the fsck command. fsck also fails with the error message above.

  1. See if the sizes of the volume and the file system match. Run the following commands and check the output:

    # fstyp -v /dev/vx/rdsk/disk_group/volume

    # vxprint -htrg disk_group -v volume

  2. If the volume is smaller than the file system, check against the previous output of the vxprint command to determine whether the space previously used by the volume is free.
  3. If the disk space previously used by the volume is free, grow the volume to occupy the same space as before. Then you can perform the fsck command on the file system.

    Note: If the disk space occupied by the volume originally is reused or overwritten, for example, with another volume or file system, this volume is no longer recoverable.
  4. If you need to free disk space, use the vxresize command to resize the file system and the underlying volume.
