Are Logical Volumes in LVM Separte from each other, like a Partition?


Even though they are on the same Volume Group?

I'm still having a hard time understanding this.

Let's say for example, that I have the following:

Code:
# df -ha

VolGroup00/LogVol2     /tmp

VolGroup00/LogVol5     /opt

VolGroup00/LogVol3     /var
I have three different Logical Volumes where /tmp, /opt and /var live. Are these separate like a partition that one would place on a physical disk?

Keep in mind that they all are on the same Volume Group as well?

yes, they all belong to VolGroup00. Yes, they are more or less partitions, separate from each other and all of them contain a filesystem. But a logical volume may reside on several physical disks.

Thanks for the response.

Right now I'm doing a proof of concept on a host with a third party database (Oracle) and want to make sure that all of the important areas (/tmp, /opt and /var) have their own space, in a sense, before I deploy the real thing.
