Hi all,
I just made a test this weekend onto my new 2 XEN hosts:
- Debian Wheezy, Kernel 3.10.7, DRBD Tools 8.4.3, Node A=master, Node
B=secondary, XEN 4.3.0 Guests on LVM
***
root at srv-ldeb-xen001:/var/local/abbeoo/xen.d# /etc/init.d/drbd status
drbd driver loaded OK; device status:
version: 8.4.3 (api:1/proto:86-101)
srcversion: 19422058F8A2D4AC0C8EF09
m:res cs ro ds p mounted
fstype
11:drbd_host11 Connected Primary/Secondary UpToDate/ UpToDate C
***
What I did is to check if synchronization works. I tested as followed:
On Node A:
1) Create a file and save it in Desktop in my XEN Guest System
2) xl destroy host11 (kill my XEN Guest System)
3) drbdadm secondary drbd_host11
Then I continue on Node B
1) drbdadm primary drbd_host11
2) xl create host11.cfg (Start my XEN Guest System)
3) No file on the desktop!!!
It seem that the synchronization doesn't work. When I shutdown Node B and
start Node A again, I see the file again on the desktop.
Can anyone help me out here? Do I make any mistake while starting DRBD at
boot?
Thanks a lot,
Walter
My Nodes are linked and working
