option -%c requires an operand
- usage:
zinject
List all active injection records.
zinject -c <id|all>
Clear the particular record (if given a numeric ID), or
all records if 'all' is specified.
zinject -p <function name> pool
Inject a panic fault at the specified function. Only
functions which call spa_vdev_config_exit(), or
spa_vdev_exit() will trigger a panic.
zinject -d device [-e errno] [-L <nvlist|uber|pad1|pad2>] [-F]
[-T <read|write|free|claim|all>] [-f frequency] pool
Inject a fault into a particular device or the device's
label. Label injection can either be 'nvlist', 'uber',
'pad1', or 'pad2'.
'errno' can be 'nxio' (the default), 'io', 'dtl', or
'corrupt' (bit flip).
'frequency' is a value between 0.0001 and 100.0 that limits
device error injection to a percentage of the IOs.
zinject -d device -A <degrade|fault> -D <delay secs> pool
Perform a specific action on a particular device.
zinject -d device -D latency:lanes pool
Add an artificial delay to IO requests on a particular
device, such that the requests take a minimum of 'latency'
milliseconds to complete. Each delay has an associated
number of 'lanes' which defines the number of concurrent
IO requests that can be processed.
For example, with a single lane delay of 10 ms (-D 10:1),
the device will only be able to service a single IO request
at a time with each request taking 10 ms to complete. So,
if only a single request is submitted every 10 ms, the
average latency will be 10 ms; but if more than one request
is submitted every 10 ms, the average latency will be more
than 10 ms.
Similarly, if a delay of 10 ms is specified to have two
lanes (-D 10:2), then the device will be able to service
two requests at a time, each with a minimum latency of
10 ms. So, if two requests are submitted every 10 ms, then
the average latency will be 10 ms; but if more than two
requests are submitted every 10 ms, the average latency
will be more than 10 ms.
Also note, these delays are additive. So two invocations
of '-D 10:1', is roughly equivalent to a single invocation
of '-D 10:2'. This also means, one can specify multiple
lanes with differing target latencies. For example, an
invocation of '-D 10:1' followed by '-D 25:2' will
create 3 lanes on the device; one lane with a latency
of 10 ms and two lanes with a 25 ms latency.
zinject -I [-s <seconds> | -g <txgs>] pool
Cause the pool to stop writing blocks yet not
report errors for a duration. Simulates buggy hardware
that fails to honor cache flush requests.
Default duration is 30 seconds. The machine is panicked
at the end of the duration.
zinject -b objset:object:level:blkid pool
Inject an error into pool 'pool' with the numeric bookmark
specified by the remaining tuple. Each number is in
hexadecimal, and only one block can be specified.
zinject [-q] <-t type> [-C dvas] [-e errno] [-l level]
[-r range] [-a] [-m] [-u] [-f freq] <object>
Inject an error into the object specified by the '-t' option
and the object descriptor. The 'object' parameter is
interpreted depending on the '-t' option.
-q Quiet mode. Only print out the handler number added.
-e Inject a specific error. Must be one of 'io',
'checksum', 'decompress', or 'decrypt'. Default is 'io'.
-C Inject the given error only into specific DVAs. The
DVAs should be specified as a list of 0-indexed DVAs
separated by commas (ex. '0,2').
-l Inject error at a particular block level. Default is 0.
-m Automatically remount underlying filesystem.
-r Inject error over a particular logical range of an
object. Will be translated to the appropriate blkid
range according to the object's properties.
-a Flush the ARC cache. Can be specified without any
associated object.
-u Unload the associated pool. Can be specified with only
a pool object.
-f Only inject errors a fraction of the time. Expressed as
a percentage between 0.0001 and 100.
-t data Inject an error into the plain file contents of a
file. The object must be specified as a complete path
to a file on a ZFS filesystem.
-t dnode Inject an error into the metadnode in the block
corresponding to the dnode for a file or directory. The
'-r' option is incompatible with this mode. The object
is specified as a complete path to a file or directory
on a ZFS filesystem.
-t <mos> Inject errors into the MOS for objects of the given
type. Valid types are: mos, mosdir, config, bpobj,
spacemap, metaslab, errlog. The only valid <object> is
the poolname. range cannot be specified when type is 'dnode'
