Hello Stefan,
The status was "HEALTH_OK" before i ran those commands.
I removed the OSDs with:
ceph osd out osd.10
ceph auth del osd.10
systemctl stop ceph-osd@10
ceph osd rm 10
umount /var/lib/ceph/osd/ceph-10
ceph osd crush remove osd.10
dd if=/dev/zero of=/dev/sdc
ceph osd out osd.9
ceph auth del osd.9
systemctl stop ceph-osd@9
ceph osd rm 9
umount /var/lib/ceph/osd/ceph-9
ceph osd crush remove osd.9
root@ceph01:~# ceph osd crush rule dump
[
{
"rule_id": 0,
"rule_name": "replicated_ruleset",
"ruleset": 0,
"type": 1,
"min_size": 1,
"max_size": 10,
"steps": [
{
"op": "take",
"item": -1,
"item_name": "default"
},
{
"op": "chooseleaf_firstn",
"num": 0,
"type": "host"
},
{
"op": "emit"
}
]
}
]
Thanks,
Mario
