Re: Is it ok to add a luminous ceph-disk osd to nautilus still? - ceph-users

2 Mar 2020

ceph-disk is not available in Nautilus.

why scrub first? It is a new disk not having any data yet. Scrubbing is 
verifying pg's not?

I just created a vm on the ceph node where I want to add this osd. Did a 
passthru of the disk and installed a few rpm's with nodeps to get the 
ceph-disk command.

Ensure that it gets scrubbed at least once by Luminous first.  But how 
and why are you doing this ? Why not use Nautilus binaries ?

 If I create and osd with luminous 12.0.3 binaries, can I just add it 
 to an existing Nautilus cluster?

 I sort of did this already, just wondered if there are any drawbacks.
