Hi David,
Yes its clones to the ceph folder. Its only that module which seems to
complain, which is a bit odd.
I might try and pop onto IRC at some point.
Many Thanks,
Nick

Hi,
The Ceph cluster we are running have few OSDs approaching to 95% 1+ weeks
ago so I ran a reweight to balance it out, in the meantime, instructing
application to purge data not required. But after large amount of data

Hi Ceph users,
I need to have different filesystem trees in different pools, mainly for
security reasons.
So I have ceph users (cephx) with specific access on specific pools.
I have one metadata pool ('metadata') and tree data pools ('data',
'wimi-files, 'wimi-recette-files').
I used file
Running into weird issues here as well in a test environment. I don't have a
solution either but perhaps we can find some things in common..

public/cluster network in 10 Gbps)
- iSCSI Proxy node
Hi Sage,
Thank you for your answer.
So, there is no anticipated problem with how I did ?
Does the 'data' pool performance affects directly my filesystem
performance, even if there is no file on it ?
Do I need to have the same performance policy on 'data' pools than on
the other pools ?
Can I

Hi all,
Just providing an update to this -- I started the mds daemon on a new server
and rebooted a box with a hung CephFS mount (from the first crash) and the
problem seems to have gone away.
I'm still not sure why the mds was shutting down with a Caught signal,
though.
Cheers,
Lincoln

Wido,
just an educated guess:
Did you check the offload settings of your NIC?
ethtool -k IFNAME should you provide that.

any special parameters (or best practice) regarding the offload
settings for the NICs? I got two ports: p4p1 (Public net) and p4p2
(Cluster internal), the cluster internal has MTU 9000 across all the
OSD servers and of course on the SW ports:
ceph@cephosd01:~$ ethtool -k p4p1

That's interesting.
Although I'm running 3.16.7 and that I'd expect the patch to be in already,
I'll downgrade to the working 3.16.0 kernel and report back if this fixes the
issue.
Thanks for the pointer.
