InnoDB offline file checksum utility.
|
|
Usage: innochecksum [-c] [-s <start page>] [-e <end page>] [-p <page>] [-v] [-a <allow mismatches>] [-n] [-C <strict-check>] [-w <write>] [-S] [-D <page type dump>] [-l <log>] [-e] <filename or [-]>
|
|
-?, --help Displays this help and exits.
|
|
-I, --info Synonym for --help.
|
|
-V, --version Displays version information and exits.
|
|
-v, --verbose Verbose (prints progress every 5 seconds).
|
|
-c, --count Print the count of pages in the file and exits.
|
|
-s, --start-page=# Start on this page number (0 based).
|
|
-e, --end-page=# End at this page number (0 based).
|
|
-p, --page=# Check only this page (0 based).
|
|
-C, --strict-check=name
|
|
Specify the strict checksum algorithm by the user.. One
|
|
of: crc32, crc32, innodb, innodb, none, none
|
|
-n, --no-check Ignore the checksum verification.
|
|
-a, --allow-mismatches=#
|
|
Maximum checksum mismatch allowed.
|
|
-w, --write=name Rewrite the checksum algorithm by the user.. One of:
|
|
crc32, crc32, innodb, innodb, none, none
|
|
-S, --page-type-summary
|
|
Display a count of each page type in a tablespace.
|
|
-D, --page-type-dump=name
|
|
Dump the page type info for each page in a tablespace.
|
|
-l, --log=name log output.
