NAME

6       lizardfs-filerepair - repair broken files
7

SYNOPSIS

9       lizardfs filerepair [-n|-h|-H] FILE...
10

DESCRIPTION

12       filerepair deals with broken files (those which cause I/O errors on
13       read operations) to make them partially readable. In case of missing
14       chunk it fills missing parts of file with zeros; in case of chunk
15       version mismatch it sets chunk version known to mfsmaster to highest
16       one found on chunkservers.
17
18           Note
19           Because in the second case content mismatch can occur in chunks
20           with the same version, it’s advised to make a copy (not a
21           snapshot!) and delete original file after "repairing".
22

OPTIONS

24       -c
25           This option enables correct-only mode, which will restore chunk to
26           a previous version if possible, but will never erase any data.
27
28       -n, -h, -H
29           These options are described in lizardfs(1).
