ndb_print_file obtains information from an NDB Cluster Disk Data file.
ndb_print_file [-v] [-q] file_name+
file_name is the name of an NDB
Cluster Disk Data file. Multiple filenames are accepted,
separated by spaces.
Like ndb_print_schema_file and
ndb_print_sys_file (and unlike most of the
NDB utilities that are
intended to be run on a management server host or to connect to
a management server) ndb_print_file must be
run on an NDB Cluster data node, since it accesses the data node
file system directly. Because it does not make use of the
management server, this utility can be used when the management
server is not running, and even when the cluster has been
completely shut down.
ndb_print_file supports the following options:
-v: Make output verbose.
-q: Suppress output (quiet mode).
-?: Print help message.
This option did not work correctly prior to NDB 7.2.18. (Bug #17069285)
