[linux-lvm] merging 2 logical volumes in same volume group

[Bipin Butala]

i have two logical volumes in the same volume group and was
wondering if/how it would be possible to merge them into a single
logical volume, without having to migrate the data.

i attempted to extend the filesystem at the time of creation but
ran into the error
  "not enough physical extents to create"
i couldn't find much documentation regarding this error.
any suggestions or ideas are greatly appreciated.

here are some outputs.

[root at fido-1]# ls /dev/fido_vg/
group  lv1-fido  lv2-fido

[root at fido-1]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hdg1" of VG "fido_vg" [55.91 GB / 412 MB free]
pvscan -- ACTIVE   PV "/dev/hde1" of VG "fido_vg" [55.91 GB / 416 MB free]
pvscan -- ACTIVE   PV "/dev/hdf1" of VG "fido_vg" [57.24 GB / 0 free]

[root at fido-1]# lvscan

lvscan -- 2 logical volumes with 225.01 GB total in 1 volume group
