Resolved.
Apparently it took the OSD almost 2.5 hours to fully boot.
Had not seen this behavior before, but it eventually booted itself back into
the crush map.

Attempting to adjust parameters of some of my recovery options, I restarted a
single osd in the cluster with the following syntax:

The osd restarts without issue, status shows running with the PID.

Hey Patrick,
I work for Cisco.
We have a 200TB cluster (108 OSDs on 12 OSD Nodes) and use the cluster for
both OpenStack and VMware deployments.
We are using iSCSI now, but it really would be much better if VMware did
support RBD natively.
We present a 1-2TB Volume that is shared between 4-8 ES

Hi All
I have a few questions pertaining to management of MONs and OSDs. This is
in a Ceph 2.x context only.
---
1) Can MONs be placed in something resembling maintenance mode (for
firmware updates, patch reboots, etc.). If so how? If not how addressed?

The fundamental problem seems to be the same in each case, related to a
missing master_zone in the zonegroup. Like yours, our cluster has been
running for several years with few config changes, though in our case,
the 10.2.3 radosgw simply doesn't start at all, logging the following error:

Which version of ceph did you use before upgrading to 10.2.3 ?

Hello,
I have a Ceph Cluster with 5 Server, and 40 OSD. Aktual on this Cluster
are 85GB Free Space, and the rsync dir has lots of Pictures and a Data
Volume of 40GB.
The Linux is a Centos 7 and the Last stable Ceph. The Client is a Debian
8 with Kernel 4 and the Cluster is with cephfs mounted.

do you try to restart osd to se the memory usage?

Hi Orit,
The radosgw service has been configured about two years ago using the
documentation on the ceph.com website. No changes to configuration has been
done since. The service was working fine until the 10.2.3 update recently. I
have been updating ceph to include every major release and prac

Adding the parameter "--iodirect=1" to the fio command line, it does not
get stuck anymore.
This is how it looks now my script:
for operation in read write randread randwrite; do
for rbd in 4K 64K 1M 4M; do
for bs in 4k 64k 1M 4M ; do

Hi,
I work with Tomasz and I'm investigating this situation. We still don't
