Cent OS RAID1
I have dedicated SolusVM slave server with KVM virtualization. When i order the server i got two 500 GB disk's configured to RAID1 array. as per SolusVM documantation DC guy's setup 40GB for / because i only use Windows template only and they leave rest of space to volume group. now my volume group has no more free space. if i order another 1 or 2 disk's can i add them to existing RAID1 and volume group ?

Adding more HDDs to RAID 1 will put them as spare HDDs.
How about getting another node .. set it up with 4x HDDs and RAID 10? Gives the boost and the security .. and happy clients :-)
You could set up a RAID-1 with two drives, and back them up to a third drive which could be used as an external drive. Or you can just add two new drives and continue to use RAID-1 or use RAID-10 (recommended).
I think you meant minimum? You can also do RAID 1 with 4 drives.
Ah yes, my mistake. I edited my post.
I think @HaroldM meant to create a new raid1 with 2hdd and then add the new partition to the lvm, which is doable
Yes, that is possible too, but I am sure if you were to recommend something (for potential client use) you'd give them RAID10 over RAID 1 any day.
is there any way to convert my existing RAID1 to RAID10 by adding another 2 Disks ?
wow. i just wait for this answer. thank you very much. now i know it's possible need to hire sysmin now
