Thanks for the confirmation! May I suggest putting this little nugget in
the docs somewhere? This might help clarify things for others :)

I'm hitting this same issue on 12.2.5. Upgraded one node to 12.2.10 and it
didn't clear.
6 OSDs flapping with this error. I know this is an older issue but are
traces still needed? I don't see a resolution available.
Thanks,

Hi,
Since the "where are the bionic packages for Luminous?" question remains
outstanding, I thought I'd look at the question a little further.
The TL;DR is:
Jewel: built for Ubuntu trusty & xenial ; Debian jessie & stretch
Luminous: built for Ubuntu trusty & xenial ; Debian jessie & stretch

Did you ever get anywhere with this?
I have 6 OSDs out of 36 continuously flapping with this error in the logs.

I'd do it like this:
* create 2 new mons with the new IPs
* update all clients to the 3 new mon IPs
* delete two old mons
* create 1 new mon
* delete the last old mon
I think it's easier to create/delete mons than to change the IP of an
existing mon. This doesn't even incur a downtime for the
That can happen if both a mon and an mds fail at the same time; this
is a common reason to avoid co-locating the mons with the mds.
Or when doing a controlled shutdown: take the mds down first and only
take the mon down once the mds state settled.
(I think it shouldn't take 3 minutes for it to
Oh, I've seen this bug twice on different clusters with Luminous on EC
pools with lots of snapshots in the last few months. Seen it on 12.2.5
and 12.2.10 on CentOS.
It's basically a broken object somewhere that kills an OSD and then
gets recovered to another OSD which then also dies

Hello
I am considering using logical volumes of an NVMe drive as DB or WAL
devices for OSDs on spinning disks.
The documentation recommends against DB devices smaller than 4% of slow
disk size. Our servers have 16x 10TB HDDs and a single 1.5TB NVMe, so
dividing it equally will result in
Hello Andreas,
we had the following experience in recent years:
1 year ago we also completely shut down one 2500+ osds ceph cluster and
had no problems to start the cluster again. ( 5 mon nodes each with 4 x
25 Gbit/s )
A few years ago, we increased the number of osds to more than 600 in
CephFS is prepared for the statx interface that doesn’t necessarily fill in
every member of the stat structure, and allows you to make requests for
only certain pieces of information. The purpose is so that the client and
MDS can take less expensive actions than are required to satisfy a full
Hello
I am experimenting with how Ceph (13.2.2) deals with on-disk data
corruption, and I've run into some unexpected behavior. I am wondering
if somebody could comment on whether I understand things correctly.
In my tests I would dd /dev/urandom onto an OSD's disk and see what
would
It'll cause problems if yours the only one NVMe drive will die - you'll lost
all the DB partitions and all the OSDs are going to be failed

Also, ephemeral instances are working fine ( disks are being created on the

That sounds like cinder is missing something regarding glance. So the
