No, with RAID1 (mirroring) I would only have half usable ... here I'm
trying to use RAID5 which means, (as a rough rule of thumb), I should
have (N-1)x(size of disk) for N disks, so for six 500GB disks I should
have (6-1)x500=2500GB usable.
Noting that that is very rough as a 500GB disk is only ~467GB usable
anyway due to the way the manafacturers define disk sizes.
Of course I could be wrong here but I normally don't expect to see a
disk in the spare state in a normal RAID5 array, (but all the arrays I
have seen using Linux Software RAID up to now have had a maximum of 4
disks and this has 6)

Hi, I've been spending the afternoon upgrading my home server and I'm having an issue with creating a RAID5 array to hold the data. Note that the OS is running on another disk and is not included on the RAID5 array and that I am using Software Raid under 10.3.
To go into the RAID5 array I have six 500GB disks. Each of these has a single Linux Raid unformatted primary partition Linux Raid partition ? How did you create those ?
I was expecting to have an array size ~3TB with ~2.5TB usable. Hi, with RAID5 only half of that would be usable, right ?
Kind regards Philippe
