Hello list,
i also tested current upstream/luminous branch and it happens as well. A
clean install works fine. It only happens on upgraded bluestore osds.

Hi,
I'm in the middle of upgrading a 12.2.8 cluster to 13.2.4 and I've
noticed that during the Yum/RPM upgrade the OSDs are being restarted.

Hi Wido,
`rpm -q --scripts ceph-selinux` will tell you why.
It was the same from 12.2.8 to 12.2.10: http://tracker.ceph.com/issues/21672
And the problem is worse than you described, because the daemons are
even restarted before all the package files have been updated.

Is this result to be expected from cephfs, when comparing to a native

I upgraded this weekend from 12.2.8 to 12.2.10 without such issues

Hi,
my use case for Ceph is serving a central backup storage.
This means I will backup multiple databases in Ceph storage cluster.
This is my question:
What is the best practice for creating pools & images?
Should I create multiple pools, means one pool per database?
Or should I create a single

An update on our cephfs kernel client troubles. After doing some
heavier testing with a newer kernel 4.19.13, it seems like it also gets
into a bad state when it can't connect to monitors (all back end
processes are on 12.2.8):

it turns out this was a kernel bug. Updating to a newer kernel - has
solved this issue.

Hi
Hi,
I'm pretty new to Ceph - pardon the newbie question. I've done a bit
of reading and searching, but I haven't seen an answer to this yet.
Is anyone using ceph to power a filesystem shared among a network of
Linux, Windows and Mac clients? How have you set it up? Is there a
mature Windows drive
Hi Ketil,
use Samba/CIFS with multiple gateway machines clustered with CTDB.
CephFS can be mounted with Posix ACL support.
Slides from my last Ceph day talk are available here:

Robert,
Thanks, this is really interesting. Do you also have any details on how a
solution like this performs? I've been reading a thread about samba/cephfs
performance, and the stats aren't great - especially when creating/deleting
many files - but being a rookie, I'm not 100% clear on the hardwa
Try lspci -vs and look for
`Capabilities: [148] Device Serial Number 00-02-c9-03-00-4f-68-7e`

Hi Ketil,
I have not tested the creation/deletion but the read/write performance
was much better then the link you posted. Using CTDB setup based on
Robert's presentation, we were getting 800 MB/s write performance for
queue depth =1 and 2.2 GB/s queue depth= 32 from a single CTDB/Samba

Hi,
you could try reducing "osd map message max", some code paths that end up
as -EIO (kernel: libceph: mon1 *** io error) is exceeding
include/linux/ceph/libceph.h:CEPH_MSG_MAX_{FRONT,MIDDLE,DATA}_LEN.
This "worked for us" - YMMV.

Hi all,
just a friendly reminder to use this pad for CfP coordination .
Right now it seems like I'm the only one who submitted something to
Cephalocon and I can't believe that ;-)
