Hi,
I've been running btrfs on Fedora for a while now, with bedup --defrag
running in a night-time cronjob.
Last few runs seem to have gotten stuck, without possibility of even
killing the process (kill -9 doesn't work) -- all I could do is hard
power cycle.
Did something change recently? Is bedup simply too out of date? What
should I use to de-duplicate across snapshots instead? Etc.?
Thanks,
Konstantin

Thanks, good to know.
Tried duperemove -- it looks like it builds a database of its own
checksums every time it runs... why won't it use BTRFS internal
checksums for fast rejection? Would run a LOT faster...

I think the reason is duperremove does extent based deduplication.
Where Btrfs checksums are 4KiB block based, not extent based. And so
many 4KiB CRC32C checksums would need to be in memory, that could be
kinda expensive. And also, I don't know if CRC32C checksums have
essentially no practical chance of collision. If it's really rare,
rather than "so improbable as to be impossible" then you could end up
with "really rare" corruption where incorrect deduplication happens.
There was a patch late last year I think to re-introduce sha256 hash
as the checksum, but as far as I know it's not in btrfs-progs yet. I
forget if that's file, extent or block based.

Yeah, duperemove doesn't use them because of the memory limitations.
Theoretically it's possible to take the the CRC checksums of the
individual blocks and then combine them to get a checksum of the blocks
as a whold, but it really isn't worth it for that (it would take just
about as long as the current hashing.
As for the collision properties of CRC32C, it's actually almost trivial
to construct collisions. The reason that it is used in BTRFS is because
there is a functional guarantee that any single bit error in a block
_will_ result in a different CRC, and most larger errors will also. In
other words, the usage of CRC32C in BTRFS is for error detection and
because it's ridiculously fast on all modern processors. As far as the
possibility of incorrect deduplication, the kernel does a bytewise
comparison of the extents submitted before actually deduplicating them,
so there's no chance (barring hardware issues and/or external influence
from a ill-intentioned third-party) of it happening. Because of this,
you could theoretically just call the ioctl on every possible
combination of extents in the FS, but that would take a ridiculous
amount of time (especially because calls involving the same byte ranges
get internally serialized by the kernel), which is why we have programs
like duperemove (while the hashing has to read all the data too, it's
still a lot faster than just comparing all of it directly).

I'm pretty sure that that patch never made it into the kernel (the
original one was for the kernel, not the userspace programs, and it
never got brought in because the argument for it (better protection
against malicious intent) was inherently invalid for the usage of
checksums in BTRFS (if someone can rewrite your data arbitrarily on
disk, they can do so for the checksums also)), and that it was block
based (and as such less useful for deduplication than the CRC32C that we
are currently using).
