lizardfs-filerepair - repair broken files


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 a missing chunk it fills the missing parts of the file with zeros; in case of a chunk version mismatch it sets the chunk version known to mfsmaster to the highest one found on the chunkservers.


Because in the second case content mismatch can occur in chunks with the same version, it is advised to make a copy (not a snapshot!) and delete the original file after “repairing”.


-n, -h, -H These options are described in lizardfs(1).
