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 ;-)

Hi folks,
My ceph cluster is used exclusively for cephfs, as follows:

root@node1:~# grep ceph /etc/fstab
node2:6789:/ /ceph ceph

"rados df" shows me the following:

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 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

Try lspci -vs and look for

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

Hi Ketil,
use Samba/CIFS with multiple gateway machines clustered with CTDB.
CephFS can be mounted with Posix ACL support.

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

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):

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

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

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.

Hello list,
i also tested current upstream/luminous branch and it happens as well. A
