About VXFEN tunable parameters

VXFEN tunable parameters describes tunable parameters for the VXFEN driver.

VXFEN tunable parameters

vxfen Parameter

Description and Values: Default, Minimum, and Maximum

vxfen_debug_sz 

Size of debug log in bytes 

  • Values

    Default: 65536

    Minimum: 65536

    Maximum: 256K

vxfen_max_delay and vxfen_min_delay 

(See below.) 

In the event of a network partition, the smaller cluster delays before racing for the coordinator disks. The time delayed allows a larger sub-cluster to win the race for the coordinator disks. The vxfen_max_delay and vxfen_min_delay parameters define the delay in seconds. 

vxfen_max_delay 

Specifies the maximum number of seconds that the smaller sub-cluster waits before racing with larger clusters for control of the coordinator disks. 

This value must be greater than the vxfen_max_delay value. 

  • Values

    Default: 60

    Minimum: 0

    Maximum: 600

vxfen_min_delay 

Specifies the minimum number of seconds that the smaller sub-cluster waits before racing with larger clusters for control of the coordinator disks. This value must be smaller than the vxfen_max_delay value. 

  • Values

    Default: 1

    Minimum: 0

    Maximum: 600
