Hey.

I've lost a bit track recently and the wiki changelog doesn't seem to
contain much about how things went on at the RAID5/6 front... so how're
things going?

Is it already more or less "productively" usable? What's still missing?

I guess there still aren't any administrative tools that e.g. monitor
for failed disks or block errors?

Does that RAID5/6 itself work already? Is it possible to replace broken
devices (or such with block errors)? Are things like a completely
failing disk (during fs being online) handled gracefully?
How about scrubbing/repairing... I assume on read it would identify
silent block errors by the checksum[0] and rebuild it if possible,
doing what when it fails? Just giving read errors? Marking the btrfs
RAID failed and remounting the fs read-only?


Cheers & thx,
Chris.

[0] Except of course for the nodatacow case, which, albeit a major
case, unfortunately still seems to lack the important checksumming
support :-(
