Description
lfs mirror verify [--only <mirror_id,mirror_id[,...]>] [--verbose|-v] <mirrored file> [<mirrored file2>...]
This command verifies that each SYNC mirror of a mirrored file specified by the path name "mirrored file" contains exactly the same data. It supports specifying multiple mirrored files in one command line.
This is a scrub tool that should be run in regular basis to make sure that mirrored files are not corrupted. The command won't repair the file if it turns out to be corrupted.
Usually administrator should check the file content from each mirror and decide which one is correct and then invoke “lfs mirror resync” to repair it manually.
If --only <mirror_id,mirror_id[,...]> option is specified, then the command will verify the mirrors specified by mirror_ids contain exactly the same data. At least two mirror ids are needed. This option cannot be used when multiple mirrored files are specified.
If --verbose|-v option is specified, then the command will print where the differences are if the data do not match. Otherwise, the command will just return an error in that case.
