Hi
Correct me if I am wrong: when uploading file to RGW it becomes split
into stripe units and this stripe units mapped to RADOS objects. This
RADOS objects are files on OSD filestore.
Whats going under the hood when I delete RGW object? If RADOS object
consists of multple stripe units belon

Hi, thanks for the explanation:-)
On the other hand, I wonder if the following scenario could happen:
A program in a virtual machine that uses "libaio" to access a file
continuous submit "write" requests to the underlying file system which
translates the request into rbd requests. Say,

You'll leave a big hole, Patrick. It's been great having you along for
the ride.

Have a 20 OSD cluster -"my first ceph cluster" that has another 400 OSDs
enroute.
I was "beating up" on the cluster, and had been writing to a 6TB file in
CephFS for several hours, during which I changed the crushmap to better
match my environment, generating a bunch of recovery IO. After about 5.
Hi,
Another newbie question. Do people using radosgw mirror their buckets
to AWS S3 or compatible services as a backup? We're setting up a
small cluster and are thinking of ways to mitigate total disaster.
What do people recommend?
Thanks,

If we are seeing this rise unnaturally high (e.g >140K - which corresponds with
slow access to CephFS) do you have any recommendations of where we should be
looking - is this related to the messenger service and its dispatch/throttle

Hi,
This is my first ceph installation. It seems to tick our boxes. Will be
using it as an object store with radosgw.
I notice that ceph-mon uses zookeeper behind the scenes. Is there a way to
point ceph-mon at an existing zookeeper cluster, using a zookeeper chroot?
Alternatively, might cep
Sorry to see you go Patrick. You've been at this as long as I have. Best of

Hi Wido,
I see your point. I would expect OMAPs to grow with the number of objects but
multiple OSDs getting to multiple tens of GBs for their omaps seems excessive.
I find it difficult to believe that not sharding the index for a bucket of 500k
objects in RGW causes the 10 largest OSD omaps to

Hi Alfredo,
This is solved, all the listening ports were disabled in my setup, after
allowing the monitor/osd ports.

Hi Ben!
Thanks for your advice. I included the names of our gateways, but did omit
the external name of the service itself. Now, everything is working again.
And yes, this change is worth a note J
