hi,
i'd been already asked, but don't get any answer. what is the maximum

thanks in advance.

Providing you are using either 64bit hardware, or the 'LBD' (large
block device) config, then raid5 arrays can be up to 2^64 -
i.e. enormous - no practical limit.

I don't know what you mean by 'raid5 partition'.  If you mean like a
regular partition of a device, then the partition can be nearly as bit
as the array....

Component devices in a raid5 cannot be larger than 2 terabytes, but I
don't think you can buy devices that big yet.
