5% available capacity - can be changed?

Hi all,

Is there any way to change minimum of available space needed by Centera from 5% ?

I need to enable regeneration buffer with minimum value 1 but I getting error (listing below). In this case I do prefer have regeneration buffer active even if there would be some issues with replication or performance.

Config# set capa reg

Limit in disks per cube [0]: 1

Issue the command?

(yes, no) [no]: y

Command failed: Setting capacity regenerationbuffer limit. Can not set the regenerationbuffer size to 1 disks. The new

regenerationbuffer would result in less than 5% available capacity.

Config# show cap av

Number of nodes:                           16

Number of nodes with storage role:         16

Total Raw Capacity:             61,047,662 MB  (100%)

System Buffer:                   2,033,783 MB    (4%)

Regeneration Buffer:                     0 KB    (0%)
