We have ceph (currently 18.2.0) log to an rsyslog server with the following file name format: template (name="DynaFile" type="string" string="/tank/syslog/%fromhost-ip%/%hostname%/%programname%.log") Around May 25th this year something changed so instead of getting the usual program log names we are also getting a lot of diffent logs with weird names.

Merging two ceph clusters

by Nico Schottelius

Good morning, in the spirit of the previous thread, I am wondering if anyone ever succeeded in merging two separate ceph clusters into one? Background from my side: we are running multiple ceph clusters in k8s/rook, but we still have some Nautilus/Devuan based clusters that are hard-to-impossible to upgrade. One of the ideas was to shift over the existing workload of the older clusters into the newer clusters. In the best case the whole process would be possible while keeping everything running in the new and old cluster. One clear challenge is that the two clusters obviously have a different FSID. The pool (names) in the two clusters differ, but the pool IDs are overlapping. If anyone has ever done this or has ideas on how to accomplish this, I would be very interested in hearing your opinion.

Changing A Ceph Cluster's Front- And/Or Back-End Networks IP Address(es)

by duluxoz

Hi All, Quick Q: How easy/hard is it to change the IP networks of: 1) A Ceph Cluster's "Front-End" Network? 2) A Ceph Cluster's "Back-End" Network? Is it a "simply" matter of: a) Placing the Nodes in maintenance mode b) Changing a config file (I assume it's /etc/ceph/ceph.conf) on each Node c) Rebooting the Nodes d) Taking each Node out of Maintenance Mode Thanks in advance Cheers Dulux-Oz
