Hi Noah
Thank you for your comments.
My companies policy states that all software needs to go through a
security assessment to be allowed to use in production. As all our tools
are focused on java, a native implementation would be far easier to
handle than a java binding of librados (which

I want to mount ceph fs (using fuse) but /etc/fstab treats it as a local
filesystem and so tries to mount it before ceph is started, or indeed before
the network is even up.
Also, ceph tries to start before the network is up and fails because it can't
bind to an address. I think this is
Hi
I have asked this question in ceph-users, but did not get any
response, so I'll test my luck again, but with ceph-devel =)
Is there any way to copy part of one object into another one if they
reside in different pgs?
There is rados_clone_range, but it requires both objects to be inside one

Hi Sam,
- coll_t needs to include a chunk_id_t.
https://github.com/athanatos/ceph/blob/2234bdf7fc30738363160d598ae8b4d6f75e1dd1/doc/dev/osd_internals/erasure_coding.rst#distinguished-acting-set-positions
That would be for sanity check ? Since the rank of the chunk ( chunk_id_t )
matches the
There are two short sessions for MDS blueprints:
mds: dumpability
mds: reduce memory usage
These are both reasonably self-contained projects that are easy for people
to get involved in but have relatively high payoff in terms of MDS
performance and debuggability. If anyone is interested
The reason for the chunk_id_t in the coll_t is to handle a tricky edge case:
[0,1,2]
[3,1,2]
..time passes..
[3,0,2]
This should be exceedingly rare, but a single osd might end up with
copies of two different chunks of the same pg.
When an osd joins an acting set with a preexisting copy of the
You might try turning osd_max_backfills to 2 or 1.

improvements, but if you have any opinions about what else ceph-deploy

I already tried both values this makes no difference. The drives are not
the bottleneck.

at 1. You can also adjust down osd_recovery_max_active.

Hi,
First I would like to state that with all its limitiation, I have
managed to build multiple
clusters with ceph-deploy and without it, I would have been totally
lost. Things
that I feel would improve it include:
A debug mode where it lists everything it is doing. This will be
helpful
Applied, thanks!

BTW, I was going to add this to the testing branch but it doesn't apply to
the current tree. Can you rebase on top of ceph-client.git #testing?
Thanks!
