Oh the irony. I have an HP54L microserver that I used to boot BSD from the exact same usb key (sandisk cruzer fit). One day boot hanged badly, cold reboot fubared some data, I had to make a spare boot key which didn't have the ZFS disk config. I failed to reimport the ZFS pool properly, wiping the root nodes off the drive. 3TB of mostly inaccessible data sleeping. I still hope that I find the time and brain resources to write a program to reconstruct the metadata from the fs nodes still on disk. ZFS sources analysis gave some hint about magic numbers and other patterns that could help scan and infer node positions. Anyway, as always, be cautious. And, when too many things are down, don't fiddle. |
