Recently I tried to add another disk using the following procedure: umount /dev/concat/store1 gconcat stop store1 gconcat label store1 ad8 ad10 ad12 ad14 ad4 growfs /dev/concat/store1 ..... it was at this point that I got the incorrect superblock error after adding ad4. Now, even if I try to remove ad4 and label with the original disks (keeping the original order) it still will not mount or fsck. The exact messages are below: schroder# mount /dev/concat/store1 /store mount: /dev/concat/store1 on /store: incorrect super block Geom name: store1 State: UP Status: Total=4, Online=4 Type: AUTOMATIC ID: 1480896172 Providers: 1.

I can be reached via this email address or by my cell phone number below. The data is not life threatening since it is just my home server, but there are several hundred gigs of personal movie clips, family photos and music and whatnot. I would really like to be able to save this data if at all possible (and then make an immediate backup of it). I do believe I will be purchasing some more disks soon for a seperate duplicate machine that can clone this storage box.
