Hallo,
as I spent the whole afternoon on a similar issue... :-)
Run purge (will also remove ceph packages, I am assuming you don't
care much about the existing stuff),
on all nodes mon/osd/admin remove
rm -rf /var/lib/ceph/
on OSD nodes make sure you mount all partitions, then
Hallo, apologies for my (silly) questions, I did try to find some doc on
rbd-mirror but was unable to, apart from a number of pages explaining
how to install it.
My environment is CenOS7 and Ceph 10.2.5.
Can anyone help me understand a few minor things:
- is there a cleaner way to configure
Hallo David, all,
sorry for hi-jacking the thread but I am seeing the same issue,
although on 10.2.7/10.2.9...
Note that I am using disks taken from a SAN, so the GUIDs in my case are
those relevant to MPATH.
As per other messages in this thread, I modified:

Hallo again, replying to my own message to provide some more info, and
ask one more question.
Not sure I mentioned, but I am on CentOS 7.3.
I tried to insert a sleep in ExecStartPre in
/usr/lib/systemd/system/ceph-osd@.service but apparently all ceph-osd
are started (and retried) at the
Hallo Matthew,
I am now facing the same issue and found this message of yours.
Were you eventually able to figure what the problem is, with
erasure-coded pools?
At first sight, the bugzilla page linked by Brian does not seem to
specifically mention erasure-coded pools...
Thanks for
the instability you mention, experimenting with
BlueStore looks like a better alternative.
Thanks again

Hallo,
I am using 12.2.4 and started using "ceph balancer". Indeed it does
a great job, thanks!
I have few comments:
- in the documentation http://docs.ceph.com/docs/master/mgr/balancer/
I think there is an error, since
ceph config set mgr mgr/balancer/max_misplaced .07
Hallo Simon,
I am also about to buy some new hardware and for SATA ~400GB I was
considering Micron 5200 MAX, rated at 5 DWPD, for journaling/FSmetadata.
Is anyone using such drives, and to what degree of satisfaction?
Thanks

Hallo,
apologies for reviving an old thread, but I just wasted again one
full day as I had forgotten about this issue...
To recap, udev rules nowadays do not (at least in my case, I am
using disks served via FiberChannel) create the links
/dev/disk/by-partuuid that ceph-disk expects.

Hallo!
Discards appear like they are being sent to the device. How big of a
temporary file did you create and then delete? Did you sync the file
to disk before deleting it? What version of qemu-kvm are you running?
I made several test with commands like (issuing sync after each operation):

Hallo,
I am wondering whether I could have the admin socket functionality
enabled on a server which is a pure Ceph client (no MDS/MON/OSD/whatever
running on such server). Is this at all possible? How should ceph.conf
be configured? Documentation pages led me to write something like this:

Hallo,
I am on Jewel 10.2.10 and willing to upgrade to Luminous. I thought
I'd proceed same as for the upgrade to Jewel, by running ceph-ansible on
OSD nodes one by one, then on MON nodes one by one.
---> Is this a sensible way to upgrade to Luminous?
Problem: on first OSD node
using ceph-ansible?
Thanks for your time and help!

Hallo Cephers,
I am stuck with an incomplete PG and am seeking help.
At some point I had a bad configuration for gnocchi which caused a
flooding of tiny objects to the backend Ceph rados pool. While cleaning
things up, the load on the OSD disks was such that 3 of them "commited

I have the same issue as mentioned here, namely

rename pools).

Due to severe maintenance which is going to cause a prolonged

geographical site): my problem is with default.rgw.buckets.data pool,
which is now 100 TB.
Moreover, I'd also like to take advantage of the move to convert
