|
|
Force a vdev error.
|
|
.TP
|
|
.B "zinject \-I [\-s \fIseconds\fB | \-g \fItxgs\fB] \fIpool\fB"
|
|
Simulate a hardware failure that fails to honor a cache flush.
|
|
.TP
|
|
.B "zinject \-p \fIfunction\fB \fIpool\fB
|
|
Panic inside the specified function.
|
|
.TP
|
|
.B "zinject \-t data [\-e \fIdevice_error\fB] [\-f \fIfrequency\fB] [\-l \fIlevel\fB] [\-r \fIrange\fB] [\-amq] \fIpath\fB"
|
|
Force an error into the contents of a file.
|
|
.TP
|
|
.B "zinject \-t dnode [\-e \fIdevice_error\fB] [\-f \fIfrequency\fB] [\-l \fIlevel\fB] [\-amq] \fIpath\fB"
|
|
Force an error into the metadnode for a file or directory.
|
|
.TP
|
|
.B "zinject \-t \fImos_type\fB [\-e \fIdevice_error\fB] [\-f \fIfrequency\fB] [\-l \fIlevel\fB] [\-r \fIrange\fB] [\-amqu] \fIpool\fB"
