That is always shown, whether softraid is used on the system or not. > Is there a way to debug this? or detect or correct disk corruption so > that this chunk is properly recognized again? The dmesg will give some clues as to what is going on. Hopefully, for Some Reason, the drive just isn't showing up to the machine, the dmesg will show that. Next step, if it is in the dmesg, see if you can get an fdisk and disklabel out of it...does that look sane? > Can the chunk be manually mounted as an ffs volume? it should still > contain a normal ffs filesystem somewhere right? kinda. But rebuilding that would probably be more work than fixing the real problem. > Looking for any way to recover the data in this chunk! Any help > greatly appreciated. I think you need to start with figuring out WHY the volume vanished. Let's hope it's an electrical or mechanical problem. Nick.
