On large FS like 100gb default value of "Reserved block count" takes 5% of usable disk, can this value be safely changed to 1% and not affect a performance ? Is a reservation size of 1gb enough for 100gb disk ? And when we have even larger filesystem like 1Tb default "Reserved block count" is 50GB, is it an absolutely minimum must have reserved number of space for disk performance, or it's just a legacy concept which can be adjusted?
Thanks in advance
