[DRBD-user] Lars said Dont do that. I did.

In a thread last October (split-brain after trying to verify?) Lars Ellenberg
said:
"You adjusted network parameters (verify-alg), which we still cannot do
while keeping the connection.
So your first "adjust" to add the verify-alg had to disconnect ; then
reconnect with new parameters.
Don't do that while both are Primary."
I found that tidbit while my first online verify was running for three
hours. I'd added verify-alg md5 to my common sections and adjust all on both
nodes (which are Primary/Primary 8.3.7). The verify found some out-of-sync
blocks, so I need to detach/attach on the node that initiated the verify.
If I hear something better to do in the next few hours, I may change my
plan. If not, I guess I'll clone both drbd virtual machines, build some test
disks, modify the clones to use the test disks, new IPs and new hostnames,
attach them to some second-level ESXi hosts and create VMFS filesystems,
recreate the situation and try the detach/attach and see what happens.
Probably it will work fine<g>.
Anyone, any thoughts?
