Hi guys. For some months i had a simple working ceph cluster with 3 nodes and 3 monitors inside. Client, monitors and cluster network was at redundant 10Gbps ports in the same subnet 10.10.10.0/24.
Here is the conf ######### [global] auth client required = cephx auth cluster required = cephx auth service required = cephx auth supported = cephx cluster network = 10.0.0.0/24 filestore xattr use omap = true fsid = 169d99bb-9b62-459e-8e5e-2d101a8c17b2 keyring = /etc/pve/priv/$cluster.$name.keyring osd journal size = 5120 osd pool default min size = 1 public network = 10.0.0.0/24 osd mount options xfs = rw,noatime,inode64 [osd] keyring = /var/lib/ceph/osd/ceph-$id/keyring [mon.1] host = test2 mon addr = 10.0.0.2:6789 [mon.0] host = test1 mon addr = 10.0.0.1:6789 [mon.2] host = test3 mon addr = 10.0.0.3:6789 ########### I want for several reasons to change all the configuration at another subnet, 172.16.0.0/24 I can stop all io traffic to the cluster, scrubbing, snapshots backups and everything that would cause changes.(anything else?) Just to be sure i have scrub deep-scrub off and osd noout. What is the best way to change this setting? I don't mind rebooting if necessary. Apparently just change 10.10.10 to 172.16.0 and restart services one by one (either osds first either mons) didn't worked. Any help? As long as i have osd noout can i just stop all osds, stop mons and then start one by one again? Thanks! Nasos Pan |
