[linux-lvm] About Extending LVM size with Hardware Raid

[Vahric MUHTARYAN]

	Okey you mean create a new raid5 with new disks and add it to volume
group okey you right . 

	But My question is , Think that I have raid5 array with 3 disk ( I'm
using ICP Raid controller card )  then I add 4.th disk to my raid array ( I
know clearly that I can extend raid5 ) at this I have more disk space but I
have to intorduce it to system , and I can't imagine How ?! it's easy if I
have free partiton but I can't show this extended array like a free
partition  :( 

Thanks For your answer 
Vahric

Uh... you don't generally extend RAID 5.  But if your hardware
raid solution has unutilized disks (or disks you can add), you can
create a new logical hw raid disk and easily add that disk into existing
volume groups.

If you have left over space on your existing logical disk, that
too can be added quite easily.  You need to provide more info.
