Hello, Lets say I have a disk (SAN) where 50% of the capacity is allocated to one primary partition of type 8e LVM. That partition is a physical volume named pv_foo in volumegroup vg_bar where the logical volume lv_baz is created occupying all extents in the volume group.
If I then have to increase the size of lv_baz I need more physical extents in vg_bar. I see two possibilities: 1. Creating a new partition on the disk occupying the rest of it, creating a PV on that partition and adding the PV to vg_bar. Finallly lv_baz can be increased. 2. Increasing the size of the one primary partition (delete and recreate, same starting cylinder) on the disk and executing pvresize Additional extents will then be available in vg_bar and lv_baz can be increased in size. Both methods have drawbacks and advantages. 1 creates more clutter but is safer. 2. is possibly more dangerous (partition resize), but causes less clutter. I could also avoid a parition table at all, but prefer to have a parition there for clarity if someone sees an empty partition table and accidentally Which approach do you use and why? _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
