mfschunktool - checks chunk integrity offline
] [ -r
checks chunk integrity using stored CRC checksums in chunk's
header. It can also 'repair' chunk (fix stored checksums). This tool may be
useful to check last written chunks after possible data corruption (power down
- turn on fast mode (in this mode only last block is tested - usually this
is enough to find corrupted chunks)
- turn on repair mode (if checksums on given chunk don't match then they
will be overwritten by checksums calculated using actual data)
