Can't extend a LV (lvextend: Not enough free physical extents available.)

[himel]

I want to extend the lv on hp-ux, but I can't. One message shown that "lvextend: Not enough free physical extents available". OS Information is given bellow. Please help me ...

All the available capacity in the VG has already been used. To extend the LV, you must first add some more capacity to the VG, either by adding one or more new PVs or by extending the existing PV. Adding new PVs is usually recommended, although extending the existing PV is possible too.

Have the storage administrator present you a new disk/LUN. Use "ioscan -fnNCdisk" to confirm that it is visible to the system. If necessary, run "insf" to create the device nodes for it.

Once the new disk is visible as e.g. /dev/[r]disk/disk99, use pvcreate to initialize it as a LVM PV, and then vgextend to add it to your volume group:

pvcreate /dev/rdisk/disk99
vgextend vg26 /dev/disk/disk99

After this, you should be able to proceed with the lvextend operation as usual.

Thanks a lot. lvextend is working now.
