If groups and volumes are basically synomous, he gives up all the benfits of groups. In fact, he gives up most of the benefits of logical volumes, since each PV has to be in one group, and each VG is one LV, you're left with one LV per PV - might as well just use partitions directly. -- Ray Morris support@bettercgi.com On 10/29/2009 06:45:39 PM, Abraham P�rez wrote: > Hi everyone, > > I'm looking for some whitepapper or similar document to find any kind > of > best practices using LVM. > > For example, usually i make only one volume group in each server and > inside > it I create different logical volumes for different purposes, but > talking > with one colleague, we discover that he makes one volume group for > each > logical volume (more or less)... so my final question is: in > performance > terms, what configuration is more efficient and why? > > Please excuse my writen english, but I don't use it very often. > > Thanks for your attention, > Abraham P�rez > ------quoted attachment------ > _______________________________________________ > linux-lvm mailing list > linux-lvm@redhat.com > https://www.redhat.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
