CHECKD is a program to check the filesystem and bittable for consistent
data. CHECKD is also capable of rebuilding the bittable from the
directory information and of scanning for files which use particular
disk addresses. Commands are in the general form:
Keyword [optional arg] structure-name
Command Description
------- -----------
CHECK BITTABLE Check the consistency of the bit table by comparing
the pages marked as assigned against those pointed to
by the file system. Also writes lost page addresses
in a file.
CHECK DIRECTORY Check just directory information on the specified
structure.
LIMIT
UNLIMIT Control whether directories may contain huge amounts
of files or not. Use LIMIT to guarantee that a
particular structure can be used on small and large
systems. Use UNLIMIT to allow directories to grow
large on a structure. Note that if a directory grows
large, the structure will no longer be usable on a
small system.
REBUILD Rebuild bittable from directory information on the
specified structure.
RECONSTRUCT Reconstucts the <ROOT-DIRECTORY> on the specified
structure and then rebuilds the bit table.
CREATE Accepts configuration information for a file
structure and then creates a new file system on the
specified units.
SCAN Read a file o
