Mirror overwritten with old data - can it be recovered?
Posted on 2006-06-08
Ok, situation is this:
Server has two scsi drives which are mirrored.
Disk management shows disk0 (master of mirror set) as missing. We believe this has been the case for about one month. When the master of a mirror set goes offline my understanding is that the server would have rebooted at that point and the server would have rebooted to the slave.
Anyway, the server was shut down for general mtce and when it restarted disk0 came back online and my limited understanding of mirroring tells me that it then reinstated itself as the master of the mirror set and started to resynchronise with the slave.
The problem now is that the data on the master was about one month old and has overwritten the data on the slave which was current. I don't understand exactly how the data is copied or synchronised between the master and slave in a mirror set so my question is this: I am trying to recover the missing data using R-Studio, do I have any hope in recovering the lost data or am I wasting my time?
