Hi,
I appreciate the insistency that the directions be followed. I wholly agree.
The only liberty I took was to do a ‘yum update’ instead of just ‘yum update
ceph-osd’ and then reboot. (Also my MDS runs on the MON hosts, so it got
update a step early.)
As for the logs:

Any other thoughts? (I’ll delete/create the OSDs with ceph-deply otherwise.)

The tool detected bluestore, or rather, it failed to find a journal associated
with /dev/sda1. Scanning a single partition can cause that. There is a flag to
spit out the findings to STDOUT instead of persisting them in /etc/ceph/osd/
Since this is a "whole system" upgrade, then the upgrade documentation
instructions need to be followed:
ceph-volume simple scan
ceph-volume simple activate --all
If the `scan` command doesn't display any information (not even with the
--stdout flag) then the logs at /var/log/ceph/ceph-volume.log need to be
inspected. It would be useful to check any findings in there
Okay, this created /etc/ceph/osd/*.json. This is cool. Is there a command or
option which will read these files and mount the devices?

Hi Paul,
To do better to answer you question, I'm following:
http://docs.ceph.com/docs/nautilus/releases/nautilus/<https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdocs.ceph.com%2Fdocs%2Fnautilus%2Freleases%2Fnautilus%2F&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7C25cea362ad224625423308d71071c968%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995953227727937&sdata=D1Q0Hrg9mq2tTtfTt1kp4Ts3vBc7mertKvYy8vBWNF8%3D&reserved=0>
At step 6, upgrade OSDs, I jumped on an OSD host and did a full 'yum update'
for patching the host and rebooted to pick up the current centos kernel.
If you are at Step 6 then it is *crucial* to understand that the tooling used
to create the OSDs is no longer available and Step 7 *is absolutely required*.
ceph-volume has to scan the system and give you the output of all OSDs found so
that it can persist them in /etc/ceph/osd/*.json files and then can later be
"activated".
I didn't do anything to specific commands for just updating the ceph RPMs in
this process.
It is not clear if you are at Step 6 and wondering why OSDs are not up, or you
are past that and ceph-volume wasn't able to detect anything.

Subject: Re: [ceph-users] Upgrading and lost OSDs
Hi Peter,
Im not sure but maybe after some changes the OSDs are not being recongnized by
ceph scripts.
Ceph used to use udev to detect the OSDs and then moved to lvm, which kind of
OSDs are you running? Blustore or filestore? Which version did you use to
create them?
Cheers!

Hi,
I’m working through updating from 12.2.12/luminious to 14.2.2/nautilus on
centos 7.6. The managers are updated alright:
# ceph -s
cluster:
id: 2fdb5976-1234-4b29-ad9c-1ca74a9466ec
health: HEALTH_WARN
Degraded data redundancy: 24177/9555955 objects degraded (0.253%),
7 pgs degraded, 1285 pgs undersized
3 monitors have not enabled msgr2
...
I updated ceph on a OSD host with 'yum update' and then rebooted to grab the
current kernel. Along the way, the contents of all the directories in
/var/lib/ceph/osd/ceph-*/ were deleted. Thus I have 16 OSDs down from this. I
can manage the undersized but I'd like to get these drives working again
without deleting each OSD and recreating them.
So far I've pulled the respective cephx key into the 'keyring' file and
populated 'bluestore' into the 'type' files but I'm unsure how to get the
lockboxes mounted to where I can get the OSDs running. The osd-lockbox
directory is otherwise untouched from when the OSDs were deployed.
Is there a way to run ceph-deploy or some other tool to rebuild the mounts for
the drives?
peter
