Hi guys,
In the past few months, I've read some posts about upgrading from
Hammer. Maybe I've missed something, but I didn't really read something
on QEMU/KVM behaviour in this context.
At the moment, we're using:

Hi,
Recently I lost 5 out of 12 journal OSDs (2xSDD failure at one time).
size=2, min_size=1. I know, should rather be 3/2, I have plans to switch to
it asap.
CEPH started to throw many failures, then I removed these two SSDs, and
recreated journal OSD from scratch. In my case, all data on main O

shinjo, thanks for your help,
#1 How small is actual data?
23K, 24K, 165K , I didn't record all of them.
#2 Is the symptom reproduceable with same size of different data?
no, we have some processes to create files, the 0-byte-files became normal
after they were covered by those processes.

Hi @all,
I have a little remark concerning at least the Trusty ceph packages (maybe
it concerns another distributions, I don't know).
I'm pretty sure that before the 10.2.5 version, the restart of the daemons
wasn't managed during the packages upgrade and with the 10.2.5 version it's
the case. I

Hi John,
Thanks for your answer.
The mentioned modification of the pool validation would than allow for
CephFS having the data pools on EC while keeping the metadata on a
replicated pool, right?

Sorry for the confusion. CentOS 7.3 shipped a few hours ago.

Hi Greg
Thanks for following it up.
We are aiming to upgrade to 10.2.5 in early January. Will let you know once
that is done, and what do we get as outputs.

I’m looking at performance and storage impacts of EC vs. Replication.
After an initial EC investigation LRC is an interesting option. Can anyone
tell me the state of the LRC plugin? Is it considered production ready in
the same sense that EC is production ready in Jewel? Or is the LRC plugin
consid
Ok, thanks for your explanation!
I read those warnings about size 2 + min_size 1 (we are using ZFS as RAID6,
called zraid2) as OSDs.
Time to raise replication!

Hi Ceph(FS)ers...
I am currently running in production the following environment:
- ceph/cephfs in 10.2.2.
- All infrastructure is in the same version (rados cluster, mons, mds and
cephfs clients).
- We mount cephfs using ceph-fuse.
Since yesterday that we have ou

Sadly, yes. I had a solution but they didn't account for hard links.
When we decided we wanted to support those instead of ignoring them or

Is this still working?
Since you're using 0.94.9, bug(#12551) you mentioned was fixed.
Can you do the followings to see object appear to you as ZERO size is
