Hi, I have a 7 nodes cluster deployed using cephadm with a mixt of HDD, SSD and NVME
I would like to reconfigure some of the HDD OSDs and put their DB on NVME There are only 6 x18 TB OSDs and there is a dedicate , "empty" 1.6 TB NVME installed for this purpose The cluster is configured as EC 4+2 and is not under heavy use I would appreciate if you could advise what is the best way of achieving that As far as I was able to find, there are these 2 options 1. remove and redeploy OSDs 2. use ceph-volume Option 1 is pretty straight forward but more time consuming For Option2 though I was not able to find any clear instructions The first thing I stumbled one was how to use ceph-volume in a cephadm managed cluster on a host that does not have it ( "cephadm shell --host HOSTNAME -- ceph-volume ls" is complaining about "unrecognized arguments --host") Any help,links,suggestions will be greatly appreciated Steven _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
