Removing OSD's on a ceph-deployed cluster

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all

 

On a Ceph cluster deployed wit ceph-deploy the instructions in the doku to remove a osd seem outdated to us.

 

We did the following steps:

 

ceph osd out {osd-num}

 

sudo /etc/init.d/ceph stop osd.{osd-num} -> WON’T work as there is no osd.disk declaration in ceph.conf  hast to be replaced by:

-> sudo stop ceph-osd id={osd-num}

 

Then stop ceph-osd does not unmount the osd, so we had to add

-> sudo umount /var/lib/ceph/osd/ceph-{osd-num}

 

ceph osd crush remove osd. {osd-num}

ceph auth del osd. {osd-num}

ceph osd rm {osd-num}

 

 

regards

Andi
