Hi,
lets assume we have size=3 min_size=2 and lost some osds and now have
some placement groups with only one copy left.
Is there a setting to tell ceph to start recovering those pgs first in
order to reach min_size and so get the cluster online faster?
Regards,
Dennis

Hi all,
On my test Luminous 12.2.4 cluster, with this set (initially so I could use
upmap in the mgr balancer module):
# ceph osd set-require-min-compat-client luminous
# ceph osd dump | grep client
require_min_compat_client luminous
min_compat_client jewel
Not quite sure why min_compat_cli
Hi Guys,
The striping seems to be slightly better than non-striping write, given
that my storage is configured with 4OSS, and 48OSD. each OSD is 8+2 Raid 6
of 24TB capacity.
But still the performance is around 100MB/sec. On a single haswell core,
I'm able to get 1GB/sec with dd buffered IO.

Given what you've shown here, it's probably one of the odder cases CephFS
is subject to, rather than an actual "there's no disk space" error. How far
is the script actually getting? Is it possible your client doesn't have
permission to write to the RADOS pool and isn't finding that out until too

Hi again,
I've been happily using both Hammer and Jewel with SSD journals and

I would like to know how folks are using EC profile in the production
environment, what kind of EC configurations are you using (10+4, 5+3 ?

Hi All,
I'm having issues trying to get a 2nd Rados GW realm/zone up and
running. The configuration seemed to go well, but I'm unable to start the

Hi Josef,
The main thing to make sure is that you have set up the host/vm
running nfs-ganesha exactly as if it were going to run radosgw. For
example, you need an appropriate keyring and ceph config. If radosgw
starts and services requests, nfs-ganesha should too.
With the debug settings you've

How I can do this if ceph-disk will be removed from master?
I really don't understand: why we need LV for new osds.

I am new to Ceph and have built a small Ceph instance on 3 servers. I realize
the configuration is probably not ideal but I’d like to understand an error I’m

ceph-volume has always used LV
Hi, thanks for the quick reply. As for 1. I mentioned that i'm running
ubuntu 16.04, kernel 4.4.0-121 - as it seems the platform
package(nfs-ganesha-ceph) does not include the rgw fsal.
2. Nfsd was running - after rebooting i managed to get ganesha to bind,
rpcbind is running, though i still c

Hi Josef,
1. You do need the Ganesha fsal driver to be present; I don't know
your platform and os version, so I couldn't look up what packages you
might need to install (or if the platform package does not build the
RGW fsal)
2. The most common reason for ganesha.nfsd to fail to bind to a port
is
I think it is not working, I'am having the same problem. I'am on the
ganesha mailing list and they have given me a patch for detailed logging
on this issue, so they can determine what is going on. (Didn't have time
to this though)

Hi,
ij our case, there's only a single active MDS

We also get the health warning in case it happens.
