Anthony asked about the 'use case'. Well, I haven't gone into details
because I worried it wouldn't help much. From a 'ceph' perspective, the
sandbox layout goes like this: 4 pretty much identical old servers,
each with 6 drives, and a smaller server just running a mon to break
ties. Usual

What does “traffic” mean? Reads? Writes will have to hit the net regardless
of any machinations.

I need exactly what ceph is for a whole lot of work, that work just
doesn't represent a large fraction of the total local traffic. Ceph is
the right choice. Plainly ceph has tremendous support for replication
within a chassis, among chassis and among racks. I just need
intra-chassis traffic to

I've upgraded ceph to Octopus (15.2.3 from repo) on one of the Ubuntu 18.04
host servers. The update caused problem with libvirtd which hangs when it tries

libvirtd process simply hangs. Nothing seem to happen. The

I've tried to use the tools to find the orphan objects, but these were running

Can you check the apt sources list that exist from your ceph-deploy

That is an interesting point. We are using 12 on 1 nvme journal for our
Filestore nodes (which seems to work ok). The workload for wal + db is
different so that could be a factor. However when I've looked at the IO
metrics for the nvme it seems to be only lightly loaded, so does not
appear to
Hey Cephers,
Can someone help us out with this? Seems that it could be fixed by just
rerunning that job Goutham pointed out. We have a bunch of changes waiting
for this to merge.
Thanks in advance,

I wonder if you should not have chosen a different product? Ceph is
meant to distribute data across nodes, racks, data centers etc. For a
nail use a hammer, for a screw use a screw driver.

Hi Amit,
Yes in the non-ec pool there’re like 600 files .meta but i dont know if its
safe move to data pool.
Does anyone know if there is a way to generate a synthetic .meta only so that
the delete command is capable of deleting the file?

Hi,
Since upgrading from Nautilus 14.2.9 -> Octopus 15.2.3 two weeks ago we are
seeing large upticks in the reported size (both space and object count) for a
number of our RGW users. It does not seem to be isolated to just one user, so
I don't think it's something wrong in the users' usage
Hi
I have a few servers each with 6 or more disks, with a storage workload
that's around 80% done entirely within each server. From a
work-to-be-done perspective there's no need for 80% of the load to
traverse network interfaces, the rest needs what ceph is all about. So
I cooked up a set of

Nautilus - Bluestore OSD's created with everything on disk. Now I have
some spare SSD's - can I move the location of the existing WAL and/or DB

I suspect not - saw emails from 2018, in the negative :(
Failing that - is it difficult to add
I agree, please check for min_size to cover min 1 max 2 configs as we have
done in our software for our users since years. It is important and it can
prevent lot's of issues.

Hi All,
I really like the idea of warning users against using unsafe practices.
Wouldn't it make sense to warn against using min_size=1 instead of size=1.
I've seen data loss happen with size=2 min_size=1 when multiple failures
occur and write have been done between the failures. Effectively
