Hello,

I'm (almost) a new user of ceph (couple of month). In my university, we start to
do some test with ceph a couple of months ago.

We have 2 clusters. Each cluster have 100 OSDs on 10 servers :

Each server as this setup :

CPU : 2 x Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Memory : 128GB of Memory
OS Storage : 2 x SSD 240GB Intel S3500 DC (raid 1)
Journal Storage : 2 x SSD 400GB Intel S3300 DC (no Raid)
OSD Disk : 10 x HGST ultrastar-7k6000 6TB
Network : 1 x 10Gb/s
OS : Ubuntu 14.04
Ceph version : infernalis 9.2.0

One cluster give access to some user through a S3 gateway (service is still in
beta). We call this cluster "ceph-beta".

One cluster is for our internal need to learn more about ceph. We call this
cluster "ceph-test". (those servers will be integrated into the ceph-beta
cluster when we will need more space)

We have deploy both clusters with the ceph-ansible playbook[1]

Journal are raw partitions on SSDs (400GB Intel S3300 DC) with no raid. 5
journals partitions on each SSDs.

OSDs disk are format in XFS.

1. https://github.com/ceph/ceph-ansible

We have an issue. Some OSDs go down and don't start. It seem to be related to
the fsid of the journal partition :

> -1> 2016-03-03 14:09:05.422515 7f31118d0940 -1 journal FileJournal::open: 
> ondisk fsid 00000000-0000-0000-0000-000000000000 doesn't match expected 
> eeadbce2-f096-4156-ba56-dfc634e59106, invalid (someone else's?) journal

in attachment, the full logs of one of the dead OSDs

We had this issue with 2 OSDs on ceph-beta cluster fixed by removing, zapping
and readding it.

Now, we have the same issue on ceph-test cluster but on 18 OSDs.

Now the stats of this cluster

>                 1280 active+clean
>                 1024 creating+incomplete

We have install this cluster at the begin of February. We did not use that
cluster at all even at the begin to troubleshoot an issue with ceph-ansible. We
did not push any data neither create pool. What could explain this behaviour ?

Thanks for your help

Best regards,
