Alejandro-
Please provide the folloing information:
1) Include an example of an actual message you are seeing in dmesg.
2) Provide the output of # ceph status
3) Provide the output of # ceph osd tree

Hi all, i have to hot-swap a failed osd on a Luminous Cluster with Blue store (the disk is SATA, WAL and DB are on NVME).

I've issued a:
* ceph osd crush reweight osd_id 0
* systemctl stop (osd I'd daemon)
* umount /var/lib/ceph/osd/osd_id
* ceph osd destroy osd_id

everything seems of, but if I left everything as is ( until I wait for the replaced disk ) I can see that dmesg errors on writing on the device are still appearing.

The osd is of course down and out the crushmap.
am I missing something ? like a step to execute or something else ?

hoping to get help.
best.
