So, I had a Storage Server 2008 box (not R2) with SIS enabled on a RAID volume. It was mostly for internal non-important stuff like ISOs and Installation files, so it wasn't being backed up. The RAID is fine, but the Drive containing the OS has died, my thought was just grab a new hard drive and then install Storage Server on it, I did some reading and everything I wrote said that Storage Server 2012 supported SIS as a legacy option, and could read/write to an SIS volume. I installed Storage Server 2012, installed the RAID drivers, I can see the RAID volume just fine, but SIS isn't working, any files that have been "de-duplicated" with SIS give an error when you attempt to access them. I had thought perhaps I just need to tell Storage Server 2012 this is an SIS enabled volume but the sisadmin.exe tool isn't on the server, and I see no options to enable SIS, only de-duplication. If possible I'd really like to get this data, it'd save a lot of trouble re-downloading all the software; ideally I'd like to enable SIS, so I can disable it which would put it back into a normal partition, then I could enable de-duplication which is supposedly more effective.
Does anyone know how to get Storage server 2012 to read my SIS partition, or how to tell it to remove SIS de-duplication, so I can enabled the new de-duplication?
