Hi all,
In case people have been wondering about the background of the various questions that I
asked on these lists in the last few months:
I've been experimenting with running ZFS-on-NBD as a cloud backup solution (and
potential alternative to S3QL, which I am using for this purpose at the moment).
In case someone is interested, here is the (rather long) write-up:
https://www.rath.org/s3ql-vs-zfs-on-nbd.html
Best,
-Nikolaus

just a few comments
+ using S3 as a block device will always suffer from the fact that it really isn’t a block
device… hiding it behind any other block device interface won’t really help except in very
constrained cases (basically, what you proved again)
+ ZFS aggregates writes, which further complicates fake block device interfaces
+ there is a dev effort to come up with an object-based vdev type, but I’m not aware of
its current status
+ L2ARC is definitely not a write-through cache

Isn't ZFS getting native object storage capability soon? It was showcased
at the last OpenZFS summit.

New subject: ZFS-on-NBD - follow-up
Hi,
Following up on my last post on this topic (since there seemed to be at least some
interest): after evaluating the setup for a few weeks, I have decided that this is not as
good a solution as I had hoped.
In particular, the expected benefits of splitting data between a special vdev backed by a
bucket with small object size and a normal vdev backed by a bucket with much larger object
size did not materialize.
More details (including histograms) are available at
https://www.rath.org/zfs-on-nbd-my-verdict.html
Best,
-Nikolaus
