What about the data that were on the ZILlog SSD at the time of failure, is a copy of the data still in the machines memory from where it can be used to put the transaction to the stable storage pool?
The intent log SSD is used as 'write only' unless the system reboots, in which case it is used to support recovery. The system memory is used as the write path in the normal case. Once the data is written to the intent log, then the data is declared to be written as far as higher level applications are concerned.
If the intent log SSD fails and the system spontaneously reboots, then data may be lost.
