RAID1 size issue with PDC20265

[Alex Ryabtsev]

Hi,

being new to this list and to dmraid, I could not be so sure is my
problem is what Paul Moore describes here
(https://www.redhat.com/archives/ataraid-list/2005-February/msg00004.html - Subject: Re: Some strange behavior with Promise Fasttrak).

I am using dmraid (rc5) within Gentoo (using dmraid initrd) on Promise
integrated PDC20265 controller with patched for RAID support BIOS. It
works pretty well (although I had no chance to check raid1 , which I am
using, functionality). There is only problem that from my two 200G hard
drives I have acceseble 100G only (remember, this is RAID1, so I have to
have 200G). dmraid rc6 looks like does not helps here too much, but for
me even makes things worse - it is changing mapped set name and as far
as I can tell, fdisk show me same 100G, and I have only 3 devices
in /dev/mapper instead of 5 I'm having with rc5.

Is there any advice for my case or I am too unclear here?

Regards,
Alex
