read only data is nice for archival (which is why my backups go to CDs/DVDs since 15 years back
and bit-rot detection by md5 sums).

I'm more interested in periodically (or triggered by writes) scan and checksum all/parts
of the files on gluster volumes, and compare those checksums between replicas (wont work
for open files like databases/VM-images). I'll guess that I put my current tools
onto each brick, and whip up some scripts to compare those.

When something materializes, I'm interested in testing.
