<div dir="ltr"><div><div><div><div><br></div>Hi all,<br><br></div>I'm trying to create a simple setup containing 2 servers. One server has a filesystem on /dev/drbd0 mounted as /var/lib/libvirt/. The drbd disk is synchronised to a second 'passive' server. If something goes wrong with the primary a script should be run manually on the secondary to promote it to primary and restart all VM's. I do not intend this to be automatic.<br><br></div>The initial configuration seems to run fine until I reboot the primary server. After the primary reboots the drbd0 resource is set to Secondary/Secondary. I need to manually promote it back to Primary and restart all my services. <br><br>cat /proc/drbd <br>version: 8.4.5 (api:1/proto:86-101)<br>srcversion: 4B3E2E2CD48CAE5280B5205 <br> 0: cs:Connected ro:Secondary/Secondary ds:UpToDate/UpToDate C r-----<br> ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0<br><br><br>How can I prevent this from happening?
