Output of "cphaconf show_bond" command on VSX cluster shows the second slave as "Not available"
Symptoms

  • When you create a new bond in Gaia Clish with only two physical slaves on VSX cluster, the output of "cphaconf show_bond" command shows the second added slave as "Not available"

    Example:

    • [Expert@Member_1:0]# cphaconf show_bond bond0

Bond name:      bond0
Bond mode:      High Availability
Bond status:    UP 
Configured slave interfaces: 2
In use slave interfaces:     2
Required slave interfaces:   1

Note: No backup slaves. Bond High Availability cannot perform failover.

eth4            | Active          | Yes
eth5            | Not Available   | Yes

    • [Expert@Member_2:0]# cphaconf show_bond bond0

Bond name:      bond0
Bond mode:      High Availability
Bond status:    UP 
Configured slave interfaces: 2
In use slave interfaces:     2
Required slave interfaces:   1

Note: No backup slaves. Bond High Availability cannot perform failover.

eth4            | Not Available   | Yes

Cause

The function that calculates whether the Bond interface is able to perform failover is called before the slave count of the bond interface is increased, making the bond incorrectly believe it has no slaves when the function is invoked.
