Hello Community,
I'm making some changes and I would like to hear your opinion on the topic.
First, let me share my setup.
I have 3 systems with in a replica 3 arbiter 1 hyperconverged setup (oVirt) which use 1 gbit networks for any connectivity.
I have added 4 dual-port 1 gbit NICs ( 8 ports per machine in total) and connected them directly between ovirt1 and ovirt2 /data nodes/ with LACP aggregation (layer3+layer4 hashing).
As ovirt1 & ovirt2 are directly connected /trying to reduce costs by avoiding the switch/ I have setup /etc/hosts for the arbiter /ovirt3/ to point tothe old IPs .
So they look like:
ovirt1 & ovirt2 /data nodes/ /etc/hosts:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.90 ovirt1.localdomain ovirt1
192.168.1.64 ovirt2.localdomain ovirt2
192.168.1.41 ovirt3.localdomain ovirt3
10.10.10.1 gluster1.localdomain gluster1
10.10.10.2 gluster2.localdomain gluster2
ovirt3 /etc/hosts:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#As gluster1 & gluster2 are directly connected , we cannot reach them.
192.168.1.90 ovirt1.localdomain ovirt1 gluster1
192.168.1.64 ovirt2.localdomain ovirt2 gluster2
192.168.1.41 ovirt3.localdomain ovirt3
Do you see any obstacles to 'peer probe' and then 'replace brick' the 2 data nodes.
Downtime is not an issue, but I preffer not to wipe the setup.
Thanks for reading this long post and don't hesitate to recommend any tunings.
I am still considering what values to put for the client/server thread count.
Best Regards,
Strahil Nikolov
