Hi Alvaro:
From the code , I see unsigned need = monmap->size() / 2 + 1; So
for 2 mons , the quorum must be 2 so that it can start election.
That's why I use 3 mons. I know if I stop mon.0 or mon.1 , everything
will work fine. And if this failure happens, it must be handled by
human ? Is the

if the network between mon.0 and mon.1 is cut off, it is easy to reproduce.

Z,
You are forcing a byzantine failure, the paxos implemented to form the
consensus ring of the mon daemons does not support this kind of failures,
that is why you get and erratic behaviour, I believe is the common paxos
algorithm implemented in mon daemon code.

Hi!
Having to interrupt my bluestore test, I have another issue since upgrading
from Jewel to Luminous: My backup system (Bareos with RadosFile backend) can no
longer write Volumes (objects) larger than around 128MB.
(Of course, I did not test that on my test cluster prior to upgrading the

It's possible, but the digest error mea
I would also recommend keeping each pool at base 2 numbers of PGs. So with
the 512 PGs example, do 512 PGs for the data pool and 64 PGs for the
metadata pool.

Also please search the ML door min_size=1. Curiously you're doing it with

Hi,
we have a 144 OSD 6 node ceph cluster with some pools (2 repl and EC).
Today I did an CEPH (10.2.5 -> 10.2.7) and kernel update and rebooted
two nodes.
on both nodes some OSDs dont get mountet and on one node I get some
dmesg like:
attempt to access beyond end of device

Hello,
How to view latest OSD epoch value in luminous. Normally this can be found
by below command.
#ceph -s | grep osd
or
#ceph osd stat
Need to know how to find this from v12.1.0
Thanks

Sorry to bring up an old post but on Kraken I am unable to repair a PG that is

Hi!
Thanks for the super-fast response!
That did work somehow... Here's my commandline (As Bluestore seems to still
require a Journal, I repurposed the SSD partitions for it and put the DB/WAL on
the spinning disk):

Hi!
Thanks for the hint, but I get this error:
[ceph_deploy][ERROR ] ConfigError: Cannot load config: [Errno 2] No such file
or directory: 'ceph.conf'; has `ceph-deploy new` been run in this directory?
Obviously, ceph-deploy only works if the cluster has been managed with
ceph-deply all along
Hello,
We are using cache-tier in Read-forward mode (replica 3) for accelerate
reads and journals on SSD to accelerate writes. We are using only RBD. Based
on the ceph-docs, RBD have bad I/O pattern for cache tier. I'm looking for
information about other possibility to accelerate reads on RBD wi
Good to know. Frankly, the RGW isn’t my major concern at the moment, it seems
to be able to handle things well enough.
It’s the RBD/CephFS side of things for one cluster where we will eventually
need to support IPv6 clients but will not necessarily be able to switch
everyone to IPv6 in one go.
