need to supernet the datacenter network PetaSAN resides on

we currently have a 10.10.21.xx / 24 in the datacenter and need to supernet it by changing the subnet from 255.255.255.0 to 255.255.252.0 and going to a 10.10.24.xxxwill the Ceph cluster just come back up and populate after we change the ips?  I have the following steps outlined

three server cluster residing on latest build of petasan, two 10gig ethernet being used each server

shutdown and disconnect all iscsi

log into console and manually change all ips

reboot all servers and change iscsi paths to new ips

 

I am going to follow these instructions and if there is anything you want to add let me know, again thank you for all you do here, this is an amazing storage environment

 

edit:

cluster_info.json

node_info.json

/etc/network/interfaces

To change /etc/hosts, you need to work through more steps as this file is synced automatically by a background sync service

# stop auto sync service
systemctl stop petasan-file-sync
# manual change hosts file
nano /etc/hosts
# sync the hosts file to all nodes:
/opt/petasan/scripts/util/sync_file.py /etc/hosts
# restart the sync service on current node
systemctl start petasan-file-sync

 

 

again thank you for all you do here, this is an amazing storage environment

Thank you, this is nice to hear  🙂

But unfortunately changing the backend ip is not straightforward.  this specific ip is used by Ceph mons, Gluster and Consul services and changing their ips is not a simple operations, you may read their docs on how to do it. You could also buy support from us if you wish and we would take care of this. Changing other ips, subnets, interfaces, bonds...etc should not be a problem.

 

ok thank you I will take this into consideration
