Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it for swap) md2 All remaining space (use it for /) 2) Created two physical LVMs, one on md0, the other on md1. 3) ? This is were I am confused, do I create two LVM volume groups? I was thinking that my primary LVM can be ~1TB and that my other LVM which I snapshot to can also be ~1TB. Anyways, I am very green on this topic as I usually do hardware raids but I don't have that option. Thanks in advance, - aurf
