Hi,
'ceph osd ok-to-stop' is a safety check, nothing more. It basically
checks if PGs would become inactive if you stopped said OSD or if
those PGs would become only degraded. Which OSD does report that it's
unsafe to stop? Can you paste the output of 'ceph osd ok-to-stop
<OSD_ID>'? And with that also 'ceph osd pool ls detail' to see which
pool(s) is/are affected. And 'ceph osd df tree' can also be useful here.
Regards,
Eugen

Hi,
I'm trying to update my cluster (19.2.2 -> 19.2.3), mon and mgr
upgrade goes well but I had some issue with OSD :
Upgrade: unsafe to stop osd(s) at this time (165 PGs are or would
become offline)
Cluster is in health_ok
All pools are replica 3 and pgs active+clean
autoscaler is off following the ceph docs
Does ceph osd ok-to-stop lead to lost data ?
The only rules used in the cluster is replicated_rule :
root@ceph-monitor-1:/# ceph osd crush rule dump replicated_rule
{
"rule_id": 0,
"rule_name": "replicated_rule",
"type": 1,
"steps": [
{
"op": "take",
"item": -1,
"item_name": "inist"
},
{
"op": "chooseleaf_firstn",
"num": 0,
"type": "host"
},
{
"op": "emit"
}
]
}
