So I couldn't mount my 32TB RAID (where the xfsdump file was). I think you misunderstood what I meant. You appear to have booted into rescue mode, but that's not what I meant. What I meant is good old single user mode. The state you'll get with "telinit 1" or with "s" or "1" as a kernel boot option. For what you want to do not a single reboot is required.
