Hello,
I have a working NFS - HA - DRBDB v9 with reactor (primary / secondary and one arbiter diskless).
I want to change the secondary by another server (exactly same hardware except the location in datacenter) without losing data and access to NFS for client (no downtime).
My plan :
- evict the secondary node B with IP 192.168.1.X and changes IP adress to 192.168.1.Y
- install new server with IP 192.168.1.X
- initialize DRBD ressource on the new server it’will connect to primary and resync right ?
Or it’s better to change configuration and use another IP ?
I’m worried about reloading the reactor or drbd configuration and crashing the NFS service.
Or there is a better way to acheieve this ?
Thanks
Yathus
