I'm performing a new Ubuntu Server installation, on hardware RAID 10, 6 x 1.72TB SSD, total space to partition is 5.8TB. The server is going to be used for KVM virtualisation.
I've allocated 500MB for /boot ext4
2GB for swap
Leaving 5.8T for / ext4
At 5% reserved blocks for the / partition, this is 290GB of space that I would ideally like to be able to use.
Is 290GB of reserved blocks overkill? I have read up what it's used for, but i'm getting mixed opinions, some say it only needs to be as big as the larges file, others say it's required.
My gut feeling is that the good folks of the linux world know what they're doing and it's set to 5% for a reason, but i'd like to take opinions on this.
