Hello Forum,
My Problem: my server wouldn't come back up after a reboot. It is a 8.2-RELEASE system, running a two-disk ZFS mirror setup. It is a dedicated box in a remote datacenter. I can boot up some linux-based rescue system.
The way I installed FreeBSD on it was with mfsbsd, the zpool was created as such:
That worked perfectly for half a year. Suddenly, it wouldn't come back up after a reboot.
What I want to do now is mount the filesystem and check for misconfiguration. So I once again booted into the linux-based rescue system, dd'd mfsbsd onto the first disk (/dev/sda), booted it up. This FreeBSD-based system is called "prealpha". That's where I am now:
The devices changed name from ad4/ad6 to ada0/ada1 because mfsbsd loads the ahci module now. I want to mount the zpool from ada1, and view/edit some configuration files. After that, I want to restore the mirror setup with with ada0 and ada1 and try to boot again.
How do I do that? Any help would be appreciated, I probably forgot to mention vital details, I am in a bit of a panic right now. Please tell me if you need more details.
