That's fortunate, maybe something can be saved from that.

I see. Extremely expensive to reproduce... 

If you know the file structure and the metadata isn't much ineresting,
a simple perl or python script can scrap the raw device for the data.
I've done it before. I can send you code snippets if you want.

Did you have any success compiling xfs_irecover?

It's a side note but one of my customers is specialised in seismic data
acquisition, and record every data twice on two different RAID-1
systems and always keep at least two copies of everything, plus an
on-tape copy... A commodity 16TB NAS costs much less (10000 € or less)
than the data it holds and makes a nice backup system. NOTHING replaces
a backup. Your system WILL fail someday (well it has now apparently).
