Hi,
This is on SLES 11 SP4 (Pacemaker 1.1.12).
I recently found out, within the crm shell, that there's the "reboot"
option that you can use with standby. It will put the node in standby
node until it gets rebooted (I like it). However when I use it, there's
no indication (anywhere) that the node is indeed in standby node.
All works as expected: resources are moved away and you can't move
resources back into it until it gets rebooted. It's just that I
expected it to appear as "standby" before the reboot occurs.
Here's an example:
crm(live)node# list
sles11a: normal
standby=off
sles11b: normal
standby=off
crm(live)node# standby sles11a
sles11a: normal
standby=on
sles11b: normal
standby=off
ok...
crm(live)node# online sles11a
sles11a: normal
standby=off
sles11b: normal
standby=off
crm(live)node# standby sles11a reboot
sles11a: normal
standby=off
sles11b: normal
standby=off
At this point all resources are moved away from sles11a and you can't
start any on it until it gets rebooted. I even tried: "crm configure
edit" but I don't see any indication of a reboot pending or a flag
somewhere indicating that it's indeed in standby node. Maybe this is
handled outside the CIB I guess.
Thanks for any feedback.
Regards,
Jorge
