h5clear clears superblock status flag field, removes metadata cache image, prints
EOA and EOF, or sets EOA of a file. It is not a general repair tool and should not
be used to fix file corruption. If a process doesn't shut down cleanly, the
superblock mark can be left that prevents opening a file without SWMR. Then,
h5clear can be used to remove this superblock mark so that the file can be inspected
and appropriate actions can be taken.
usage: h5clear [OPTIONS] file_name
OPTIONS
-h, --help Print a usage message and exit
-V, --version Print version number and exit
-s, --status Clear the status_flags field in the file's superblock
-m, --image Remove the metadata cache image from the file
--filesize Print the file's EOA and EOF
--increment=C Set the file's EOA to the maximum of (EOA, EOF) + C for
the file <file_name>.
C is >= 0; C is optional and will default to 1M when not set.
This option helps to repair a crashed SWMR file when the stored
EOA in the superblock is different from the actual EOF.
The file's EOA and EOF will be the same after applying
this option to the file.
Examples of use:
h5clear -s file_name
Clear the status_flags field in the superblock of the HDF5 file <file_name>.
h5clear -m file_name
Remove the metadata cache image from the HDF5 file <file_name>.
h5clear --increment file_name
Set the EOA to the maximum of (EOA, EOF) + 1M for the file <file_name>.
h5clear --increment=512 file_name
Set the EOA to the maximum of (EOA, EOF) + 512 for the file <file_name>.
