Dear list,
I'm looking for some guide or pointers to how people upgrade the
underlying host OS in a ceph cluster (if this is the right way to
proceed, I don't even know...)
Our cluster is nearing the 4.5 years of age and now our ubuntu 18.04 is
nearing the end of support date. We have a mixed cluster of u18 and u20
nodes, all running octopus at the moment.
We would like to upgrade the OS on the nodes, without changing the ceph
version for now (or per se).
Is it as easy as installing a new OS version, installing the ceph-osd
package and a correct ceph.conf file and restoring the host key?
Or is more needed regarding the specifics of the OSD disks/WAL/journal?
Or is it necessary to drain a node of all data and re-add the OSDs as
new units? (This would be too much work, so I doubt it ;-)
The problem with searching for information about this, is that it seems
undocumented in the ceph documentation, and search results are flooded
with ceph version upgrades.
Cheers
/Simon
