LVM Advice

[jay214128]

I have a Fedora 8 system that uses LVM on one of it's drives (/dev/sdb2). One of the logical volumes is getting full (LogVol02). There is an unused, unmounted logical volume (LogVol03) available. I can see two possible options.

1) Mount the unused logical volume (LogVol03) on a new mount point (/home2) and create more space there
2) Delete the LogVol03 logical volume and extend the nearly full volume (LogVol02) into the now available space.

Option 2 seems like the better approach, since it will seem seamless to the system users. I'm looking for suggestions on how I should go about doing this and what I need to look out for. Is it better to use the command line tools (lvm ...) or the GUI (system-config-lvm) to do this?

The logical volume is like a partition - growing a volume successfully is heavily dependent on the ability to change the *filesystem* size.

You can Google for many docs/discussions/tutorials.

Thanks for the additional links.

To close out this thread, here is what I did to increase the logical volume size.

/usr/sbin/lvextend -l +2560 /dev/VolGroup00/LogVol02
/sbin/resize2fs /dev/VolGroup00/LogVol02

I didn't even have to unmount the file system to do this. This worked because I had free physical extents available on the physical volume.
