List,
Had a failed disk behind an OSD in a Mimic Cluster 13.2.0, so I tried following
the doc on removal of an OSD.
I did:
# ceph osd crush reweight osd.19 0
waited for rebalancing to finish and cont.:
# ceph osd out 19
# systemctl stop ceph-osd@19
# ceph osd purge 19 --yes-i-really-mean-it
verified that osd.19 was out of map w/ ceph osd tree
Still found this tmpfs mounted though to my surprise:
tmpfs 7.8G 48K 7.8G 1% /var/lib/ceph/osd/ceph-19
Replaced the failed drive and then attempted:
# ceph-volume lvm zap /dev/sdh
# ceph-volume lvm create --osd-id 19 --data /dev/sdh
