[Pacemaker] Migration of "lower" resource causes dependent resources to restart

[Vladislav Bogdanov]

Hi Andrew, all,

Pacemaker restarts resources when resource they depend on (ordering
only, no colocation) is migrated.

I mean that when I do crm resource migrate lustre, I get

LogActions: Migrate lustre#011(Started lustre03-left -> lustre04-left)
LogActions: Restart mgs#011(Started lustre01-left)

I only have one ordering constraint for these two resources:

order mgs-after-lustre inf: lustre:start mgs:start

This reminds me what have been with reload in a past (dependent resource
restart when "lower" resource is reloaded).

Shouldn't this be changed? Migration usually means that service is not
interrupted...

Best,
Vladislav
