Seagate Business Storage 4-Bay NAS SRN04D Configuration

February 13th, 2015, 11:48

Had this RAID 5 in a couple of days ago. R-Studio would not detect the RAID configuration, but it built fine in UFS Explorer. So why my question? I want to learn more about this configuration not just accept that it built in UFS. I would like to study the RAID Ext file system. I know that R-Studio gives the parent and child relative sectors when looking at the RAID in Hex (which UFS doesn't) so I want to build it in R-Studio to help me piece together how the file system works and reverse engineers it. Anyone know the default?

UFS gives that too .
If you want to repeat configuration, press raid edit in UFS auto-constracted array , you will see layot , order, stripe size. Repeat it in R-Studio.

I did see that thanks. I tried the parameters in R-Studio but it still does not build. However UFS does not give the offset which may be the issue.

UFS Explorer shows everything except parent sector.

Offset is there, please check carefully.

Hey Dimitri. UFS does give the first sector of the RAID, but I presume there could be different offsets for different drives as using the first sector as the offset still doesn't build it. Could be PEBCAK of course :-)
