Hi

I have a strange problem with kernel 2.2.19 an lvm-tools 0.9.1_beta7.

I have a existing VG with 2 80GB disks containing one 160GB LV.
I added a additional 80GB disk and wanted to extend the LV. But that
didn't
work.

If I try to extend the LV with:
lvextend -L+78164M /dev/NVolGroup/nVol
then I get:
lvextend -- rounding size 240119808 KB to stripe boundary size 240123904
KB
lvextend -- only 19541 free physical extents in volume group "NVolGroup"

Next try with: lvextend -l+19541 /dev/NVolGroup/nVol
lvextend -- rounding size 240119808 KB to stripe boundary size 240123904
KB
lvextend -- only 19541 free physical extents in volume group "NVolGroup"

Where is the error?
