Hello, I've tried to upgrade our ceph cluster to pacific release (version
16.2.0 and then planned to move to each version 1 by 1) but it seems that on
our cluster, it's failing
I've installed it (long time ago...) via cephadm on version v15 (I guess it was
a v15.2.8 underneath at this time).
I remember having an issue with ceph mgr which leads to use
ceph-base:latest-octopus to fix (next version wasn't released at this time and
it was crashing the cluster by filling the logs)
the cluster state is OK:
cluster:
id: adc48d6a-61bf-11eb-9212-2f70acf7224f
health: HEALTH_OK
services:
mon: 3 daemons, quorum server36,server38,server37 (age 3h)
mgr: server36.xujjng(active, since 2h), standbys: server37.fyglah
osd: 52 osds: 52 up (since 4h), 52 in (since 4h)
rgw: 2 daemons active (2 hosts, 1 zones)
data:
pools: 11 pools, 489 pgs
objects: 1.28M objects, 4.8 TiB
usage: 15 TiB used, 65 TiB / 81 TiB avail
pgs: 489 active+clean
io:
client: 3.2 MiB/s rd, 24 MiB/s wr, 2.73k op/s rd, 1.81k op/s wr
So I tried "ceph orch upgrade start --ceph-version 16.2.0) and the first time
it deployed a new ceph mgr with 16.2.0 version and got stuck here.
After waiting several hours, I stop and restarted and nothing happened.
I've then manually upgraded the whole cluster except the 2 rgw and
grafana/prometheus/alertmanager/nodeexporter
I retried and I see nothing happening, in the different logs (in debug)
(cephadm, logs of active mgr, ceph -W cephadm --watch-debug, ...)
I also tried with 16.2.1 now as it seems 16.2.0 wasn't working but I have the
same effect
here's what I see for ceph -W cephadm --watch-debug:
2021-07-09T14:13:14.642077+0000 mgr.server36.xujjng [INF] Upgrade: Started with
target docker.io/ceph/ceph:v16.2.1
and nothing
in mgr docker logs, I see (roughly) the same line and then debug stuff not
related :
::ffff:127.0.0.1 - - [09/Jul/2021:15:08:33] "GET /metrics HTTP/1.1" 200 1423923

TiB / 81 TiB avail; 2.0 MiB/s rd, 30 MiB/s wr, 2.75k op/s
I don't see anything in cephadm logs
status is not very good also:
{
"target_image": "docker.io/ceph/ceph:v16.2.1",
"in_progress": true,
"services_complete": [],
"progress": "",
"message": ""
}
Do you know where I could find some log / info in order to see why it doesn't
start?
thanks!
Sylvain
