lizardfs filerepair [-n|-h|-H] FILE...
filerepair deals with broken files (those which cause I/O errors on read operations) to make them partially readable. In case of missing chunk it fills missing parts of file with zeros; in case of chunk version mismatch it sets chunk version known to mfsmaster to highest one found on chunkservers.
Because in the second case content mismatch can occur in chunks with the same version, it’s advised to make a copy (not a snapshot!) and delete original file after "repairing".
This option enables correct-only mode, which will restore chunk to a previous version if possible, but will never erase any data.
- -n, -h, -H
These options are described in lizardfs(1).
