.SH DESCRIPTION
|
|
.B thin_check

|
|
.B thin_check
|
|
will only return a non-zero exit code if it finds a fatal
|
|
error. An example of a on fatal error is an incorrect data block
|
|
reference count causing a block to be considered allocated when it in
|
|
fact isn't. Ignoring errors for a long time is not advised, you
|
|
really should be using thin_repair to fix them.
