NAME

       mfsmetarestore - replay LizardFS metadata change logs or dump LizardFS
       metadata image

SYNOPSIS

       mfsmetarestore [-z] -m OLDMETADATAFILE -o NEWMETADATAFILE [CHANGELOGFILE...]

       mfsmetarestore -m METADATAFILE

       mfsmetarestore [-z] -a [-d DIRECTORY]

       mfsmetarestore -g -d DIRECTORY

       mfsmetarestore -v

       mfsmetarestore -?

DESCRIPTION

       When mfsmetarestore is called with both -m and -o options, it replays
       given CHANGELOGFILEs on OLDMETADATAFILE and writes result to
       NEWMETADATAFILE. Multiple change log files can be given.

       mfsmetarestore with just -m METADATAFILE option dumps LizardFS metadata
       image file in human readable form.

       mfsmetarestore called with -a option automatically performs all
       operations needed to merge change log files. Master data directory can
       be specified using -d DIRECTORY option.

       mfsmetarestore -g with path to metadata files, prints latest metadata
       version that can be restored from disk. Prints 0 if metadata files are
       corrupted.

       -v
           print version information and exit

       -?
           print version information and exit

       -a

       -d DATAPATH

       -m METADATAFILE
