Bug #4116

IP Alias VIPs using CARP VIP as their interface are not properly deactivated for temporary CARP disable
100%
Description
When using "Temporarily Disable CARP", IP alias VIPs using a CARP VIP "interface" are still present and the interface flips back to MASTER for the alias VIPs which is unexpected/undesirable. When temporarily disabling CARP mode, the CARP VIP is removed but the aliases using it as an interface are left behind, which may be part of the issue.
When using maintenance mode, the advskew is raised which avoids that specific problem.
Easy to reproduce by adding a CARP VIP to a cluster, then adding an IP Alias VIP using that CARP VIP as its interface, and then test manual/temporary failover from Status > CARP.

The "temporary" button seems to behave OK in my test setup now but maintenance mode still does not appear to work properly when a VIP is defined. Might be still related to this, or it may be part of #3910. Entering maintenance mode is OK but it will never return to MASTER status for an interface with an IP Alias VIP on a CARP VIP. Other interfaces are OK. Feel free to close this in favor of #3910 if it's a better fit there.

confirmed current status as Jim described. Temporary is fine. Maintenance mode gets stuck at advskew 254 only on interfaces where you have an IP alias with a CARP IP parent.
