Hi,
I found that issue is related with "ETag: -0" (ends -0)
This is known bug ?

Hi,
See this one also: http://tracker.ceph.com/issues/6365
But I’m not sure the Inktank patched qemu-kvm is relevant any longer since
RedHat just released qemu-kvm-rhev with RBD support.

Yes, I would recommend increasing PGs in your case.
The pg_num and pgp_num recommendations are designed to be fairly broad to
cover a wide range of different hardware that a ceph user might be
utilizing. You basically should be using a number that will ensure data
granularity across all your OSDs.
Yes I can read it. Oryginal object is 0 size.

Gary,
Yes, Ceph can provide a highly available infrastructure. A few pointers:
- IO will stop if anything less than a majority of the monitors are
functioning properly. So, run a minimum of 3 Ceph monitors distributed
across your data center's failure domains. If you choose to add more

By any chance are you uploading empty objects through the multipart upload api?

Hi Patrick,
Aaron and Nathan are willing to take an active role in editing

Looks like it. There should be a guard against it (mulitpart upload

Hey Loic,
That's great! As for ceph-user I was referring more to a way for
people to drop content or requests on the community at large. For a
chatty discussion about website changes we can just include the
interested parties (message to follow) and others can chime in with
their desire to help
You're right.

Actually, I read that differently. It only says that if there's more
than 1 part, all parts except for the last one need to be > 5M. Which
means that for uploads that are smaller than 5M there should be zero

We're looking at using Ceph's copy-on-write for a ton of users'

is data added in normal 4kB or 64kB sizes, or can you specify block size

Maybe. If your back end network is a supernet and each cluster network is a
subnet of that supernet. For example:
Ceph.conf cluster network (supernet): 10.0.0.0/8
Thanks
Workaround, don't use multipart when obj size == 0 ?

For bobtail at this point yes. You can try the unofficial version with
that fix off the gitbuilder. Another option is to upgrade everything

Hi,
The first unofficial French ceph user meetup took place in Nantes on Friday
29th 2013. There were 8 participants.
Yann from the University of Nantes related his use case of ceph. During his
presentation we talked about hardware choices, about using SSD and problems
he has experienced in his
