Trans Metadevice Errors

Device errors can cause data loss. Read errors occurring on a logging device can cause significant data loss. For this reason, it is strongly recommended that you mirror the logging device.

If a device error occurs on either the master device or the logging device while the trans metadevice is processing logged data, the device transitions from the "Okay" state to the "Hard Error" state. If the device is either in the "Hard Error" or "Error" state, either a device error has occurred, or a file system panic has occurred.

Any devices sharing the errored logging device also go the "Error" state.
