question migrating replacing

[raqdedicados]

HI Actually we have running two servers,

raq102 master with 3 vms
raq103 slave with 3 vms

Now we are going to install another, raq104 to replace the master node, which things u would take on consideration, and

which steps u will perform to do this ? do i'm right or i will be in trouble ? should i put some special command ?

1- move all the raq102 vms to raq103
2- install proxmox on raq104 new server
3- setup raq104 as master
4- log in to raq103 and attach is as slave to raq104 ? but this will delete me all the vms running on it ?? or you would suggest, setup raq103 as master, and then attach raq104 as slave to it ??
5- distribute the vms between then

i very appreciate your help, this software is very prommising and we are very entusiastic on it ! !!

Thanks

Diego

Hi Diego,

here are the steps:

1. Move all VM´s to raq103
2. Install raq104 from ISO check IP settings and run apt-get update/upgrade
3. Join raq104 to the master: pveca -a -h raq102
4. Wait till all 3 nodes are in sync
5. Make sure that raq102 has no VM´s on it. power off (never turn on again)
6. Force raq104 to be the new master: pveca -m
7. Force raq103 to sync now from the new master: pveca -s -h raq104

Perfect! One question, when i force the resync raq103 slave to raq 104 master, i will loose the vm inside of Raq 103? I ask u coz in the manual says that slave node to join master must be empty.

Thanks !!!!

you read the manual - cool!

under normal conditions, the problem is when you join a node with VM´s to a master with VM´s you will get VMID conflicts. Thats the reason because we point this out in the manual.

but as you do have same VMID´s, this not apply here for this migration.
