[pbs-devel] [PATCH proxmox-backup 1/2] api2/status: fix estimation bug

[Dominik Csapak]

when a datastore has enough data to calculate the estimated full date,
but always has exactly the same usage, the factor b of the regression
is '0'

return 0 for that case so that the gui can show 'never' instead of
'not enough data'
