.SH DESCRIPTION
The
.B mdbx_chk
utility intended to check an MDBX database file.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-v
Produce verbose output, including summarize space and page usage statistics.
If \fB\-vv\fP is given, be more verbose, show summarized B-tree info
and space allocation.
If \fB\-vvv\fP is given, be more verbose, include summarized statistics
of leaf B-tree pages.
If \fB\-vvvv\fP is given, be even more verbose, show info of each page
during B-tree traversal and basic info of each GC record.
If \fB\-vvvvv\fP is given, turn maximal verbosity, display the full list
of page IDs in the GC records and size of each key-value pair of database(s).
.TP
.BR \-n
Open MDBX environment(s) which do not use subdirectories.
.TP
.BR \-q
Be quiet; do not output anything even if an error was detected.
.TP
.BR \-w
Open environment in read-write mode and lock for writing while checking.
This could be impossible if environment already used by another process(s)
in an incompatible read-write mode. This allow rollback to last steady commit
(in case environment was not closed properly) and then check transaction IDs
of meta-pages. Otherwise, without \fB\-w\fP option environment will be
opened in read-only mode.
.TP
.BR \-d
Disable page-by-page traversal of B-tree. In this case, without B-tree
traversal, it is unable to check for lost-unused pages nor for double-used
pages.
.TP
.BR \-s \ subdb
Verify and show info only for a specific subdatabase.
.TP
.BR \-c
Force using cooperative mode while opening environment, i.e. don't try to open
in exclusive/monopolistic mode. Only exclusive/monopolistic mode allow complete
check, including full check of all meta-pages and actual size of database file.
.TP
.BR \-i
Ignore wrong order errors, which will likely false-positive if custom
comparator(s) was used.
.SH DIAGNOSTICS
Exit status is zero if no errors occur. Errors result in a non-zero exit status
and a diagnostic message being written to standard error
if no quiet mode was requested.
